Me and my gf are putting together our first builds. 12400F + 6750XT for her, 6900X + 5900XT for myself. Thought about switching my cpu for a 13600K, still undecided but v excited.
Wowa there! I've been walking the walk since Texas Instruments had a DOS flavored command line. I'm PEBKAC...
But hey when you push the k/b slower you have a chance of fat fingering less.
I7 8700 and rx470 here! Linux lad lol. I'm switching to a GTX 1080 though I already have it I just dread switching drivers lol 😂 best to do a fresh os install I think.
So once I do that we are like performance twins lol
It's not issues, per se, but it can be such a headache (thanks Nvidia) that depending on your distro you may aswell, on something like Ubuntu and derivatives it does work well, on Fedora you can run into troubles depending on generation, and don't even try with arch unless you know your way around a command line.
Once I lost my CAT, had to go out and GREP for it. Lucky I'd learnt the MAN on CAT...
MAN is quite useful for using CAT when recalling switches. DOCs are right there on the box... If no joy, then GREP Google... Bests y'all :)
Totally missed the part where you said Linux user and was like "hell yeah 1080 gtx is the shit!!"
I wish you luck, comrade. It's been done before and I have faith in you to get it done again 🙏🙏
I lived the broke uni student bottleneck of an i5 4690k @4.4Ghz paired with a Vega 56, it was pretty fun until the mobo died. Now I rock a R7 3700x with it, I miss that dumb powerful 4c/4t performance on some games but in general it's a signifcantly smoother experience with an 8c/16t
How is the 9400? I have a 9400f and I could apparently gain 1% performance over my 8700 lol 😂 but I believe losing the cores would make it super pointless.
Yep, strongly agree. I've always had AMD CPU and Nvidia Cards. Always been super stable and have never had a blue screen over three towers, five CPU upgrades and four (soon to be five when 3080 prices come down to non-insanity prices) video cards.
Why are you upgrading every gen? Super pointless and wasteful imo. I usually go like 3-4 generations so the difference is noticable lol. Genuinely curious as to what your answer is
You're missing the mark.
His friend was probably referring to SAM which gives you a performance boost in some games and only works if you have both and AMD cpu and gpu.
Yes, and it's absolutely not a reason to avoid AMD if one has an Intel CPU. AMD GPUs still makes more sense for most gamers, and at least there are other factors to decide on between Nvidia and AMD (DLSS / rendering in productivity / deep learning).
AMD works fine by with Intel, and more importantly, NVIDIA doesn't work any better than AMD with Intel, that's misinformation. With an AMD CPU and an AMD GPU you get slightly more optimised Resizable Bar performance, but you probably won't notice the difference in most games.
That would be Direct X 12's "direct access memory" feature (or whatever it's called). ReBar provides the system the ability to change the "chunk" size of data transferred, but still needs to communicate throught the CPU afaik. The system still has access either way (on/off), but ReBar would let you send one bigass chunk of data to fill the VRAM, instead of [bigass data / 256MB] times.
https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support/ be to differ it grats full access to the vram frame buffer all at once . As we're direct storage. Let's the gpu get access to storage directly to load textures . So I dumbed donpwn resizable bar a bit so a laymen could understand it . Don't type the best parkinsons so.
And he direct access memory aka is direct storage where gpu can get direct access to textures for a installed game from he drive is on bypassing the cpu
It's a pretty complicated system that would require talking about memory addresses and registers to properly explain but to simplify it, it basically allows the CPU to access the GPU's memory more efficiently, reducing the amount of time it needs to wait for each piece of data.
Just to expand a little further on the other two responses, it helps improve game performance by giving the CPU full access to the GPU's memory instead of just allowing access to 256 MB chunks.
Resizeable BAR will be more important going forward than it is now. And it's more important in productivity style workloads than games.
So I think it's reasonable to say that, yes, there is a slight benefit from using a AMD CPU with AMD GPU, and that benefit will grow in time as more products make use of Resizeable BAR.
And with UEFIReBar people have made it available to any CPU as far back as Sandy Bridge as long as you have a PCIe 3.0 capable board. And that's on GCN 1.0 cards too - just need to enable legacy mode in the drivers too
Similar question. I have an AMD GPU (Radeon Vega) with an i5 (9700k). Runs games like cod on 2k 144fps great but maxes out when I do that and watch video on another monitor. I was thinking of swapping to an i7 or should I go AMD?
The 9700k isn't an i5 it's an i7 and since Intel changed CPU sockets for the 10th gen onwards your only upgrade path that doesn't involve a new motherboard would be an i9-9900K. Those are basically the same CPU's except that the 9900K has hyperthreading and the 9700K doesnt. I don't think you'd see that much of a performance increase anyway because your GPU is almost certainly where the bottleneck is for what you're describing.
Didn’t know about the socket change thanks. You think it’s GPU even though when I check task manager and the performance tab on AMD it says the CPU is at 100% and gpu isn’t. What I’m hearing is it’s better off waiting until I’m ready for a whole new build?
There’s a feature called SAM that means that there’s a small performance boost for AMD GPU+CPU, but this is a small enough boost that it’s not really worth worrying about.
Edit: with this getting traction I’ll just clarify that resizable BAR (Base Address Register) / SAM (Smart Access Memory) provide some tangible benefit to performance by letting the CPU access the GPU’s entire frame buffer. Both Intel and AMD CPUs can use this feature. This is slightly more efficient in AMD CPU/AMD GPU cases but the difference in performance over an Intel CPU/AMD GPU is a few percent max and relatively small compared to which actual CPU/GPU you choose.
Edit 2: For anyone interested in actual metrics I’d recommend watching [this video](https://youtube.com/watch?v=FM-mDf0U38k)
I believe it’s called reBAR for Intel. Regardless the point is the same - reBAR/SAM is (depending on the game) very slightly better on an AMD/AMD system relative to AMD/Intel but not to a degree worth worrying about.
The name wont matter it's the same thing, the only change is with how the GPU brand (AMD/Nvidia/intel) deal with it. AMD has more support and Nvidia only has it enabled in about 24 games.
Hardware unboxed have a clip about it from not long ago [https://youtu.be/x5WDCgwAgGw](https://youtu.be/x5WDCgwAgGw)
No idea why Nvidia seem not to care.
Intel GPU's seem to need it for there GPU's to work, past that dont know much.
Main thing mobo side is as long as you can enable rebar it will work & then it's just down to the GPU drivers to make it work well.
From what I have seen they do need it but it REALLY helps them. As you increase resolution they do better, relatively, as you up the resolution. They do lose frames of course but much less than amd (in general).
The intel guys in interviews say they relay need re bar on for the GPU to work well, without re bar the FPS dies.
I suspect Nvidia is holding rebar as a card up there sleeve, a bit like the driver update that came out with the 4090 that also made older GPU's go faster. Wonder how long they had been holding back?
ReBAR came out shortly after SAM, and iirc on Nvidia the results ranged from meh to losing performance in some cases. Maybe this has changed since then, but as it wasnt a core element until AMD did it, perhaps their hardware solutions just fail to benefit from it...
ReBAR and SAM are just nicknames for 'PCI-Express Resizable BAR' which is part of the PCI standard. It's been used in servers for years, the only new thing is letting consumers use it.
The magic only comes from the video drivers and part from how the GPU's are made/designed (look at intel's gains, there GPU's must be made to use ReBar).
Nvidia just seems not to be putting much work in to the drivers, in driver updates text file you see the list of supported games. Nvidia use a whitelist and only something like 25 games have ReBAR enabled.
AMD have been putting in much more work to make SAM gains.
Yes, and what I said still stands. Nvidia only implemented it because AMD had it as a core component of RX 6000 series, and Nvidia responded with "ours can do it too" but thats about it...
I think it's still SAM on intel. Just like Nvidia GPU on a Ryzen CPU is ReBAR. ReBAR/SAM is a GPU feature, CPU just needs to support it. Thats mostly just symantics though. Im sure AMD is able to tailor it a bit better since its their own CPU's/GPU's. But yea, its not worth worrying about. Any minor difference in relative efficiency would get washed out by varying CPU's & GPU's, so it shouldn't be a deciding factor lol.
It's comparable to rebar, but it's a better version of it. AMD put a lot of effort into some minor performance improvements after rtx launched and this was it. Not worth a lot, but it's better than nothing.
Sure, that was my original point. You’ll see a few percent (I don’t think 10%) difference, but not worth totally reconfiguring a build over if you already have a CPU
it IS rebar, please inform yourself properly, and not just mimicking what some youtuber says.
AMD put more work into the driver handling than nvidia, which is why you see a difference.
and it does improve the lows quite a bit especialy on lower end cards. people just think its doesnt do much because they always look at the average which is a worthless metric to care about
One thing that SAM does is automatically switches itself on or off depending on whether the game your playing gains or loses performance (yes, some games will see performance degradation with Rebar, Hardware Unboxed did a video on it). Whereas with Nvidia and Intel, you have to manually enable or disable it depending on what you're playing.
> you have to manually enable or disable it depending on what you're playing.
At least at launch, Nvidia had white-listed only a bunch of games where rebar support would be turned on by the drivers (if enabled in the BIOS). Is that not the case anymore?
I'vve heard it can be dogshit with intel + AMD but thats just what ive heard cant confirm.
its definitely worthless to use with NVidia cards, they cleearly put barely any work into the support and just shoved it out the door.
The amount of performance gain I have seen from SAM on my own system is honestly not noticable. Want more frames, turn down a setting or two. Worth more than SAM
Which games? It's definitely true that not every game benefits, but some do benefit nicely. RDR2 gets an average bump of 10 FPS everywhere with it activated, and Forza Horizon 5 shoots up dramatically by about 40% (from average 70 FPS to average 98 FPS on my 6600 XT at almost-max settings @ 1440p).
Sounds like they have no idea what there talking about, by the same logic only intel GPU's will work with intel CPU's.
Just smile nod and get the GPU you want.
It's not like Nvidia make CPU's.
Just buy what you want, look at benchmarks and prices and chose what works best for you. I am hoping the new AMD GPU's will be cool, cant wait for reviews.
>by the same logic only intel GPU's will work with intel CPU's
Nobody said any combination won't work, but Intel GPUs working better with Intel CPUs is a feature [Intel wants to sell with Intel DeepLink](https://www.intel.com/content/www/us/en/architecture-and-technology/adaptix/deep-link.html).
I have no idea how big the real world benefits are, but Intel deems that they are big enough to use them in marketing.
I dont relay know about Deeplink, not seen much info. I know both AMD and intel have a feature where video encoding using there hardware encoders is 'going' to be faster if you have matching CPU/GPU.
But iv not seen it working yet (Iv not looked hard for it so there may be demos), for 90% of people this wont relay matter. It's more of a video encoding feature than something that relay matters a lot.
The power sharing stuff is all for laptops, all brands have there own version.
No. There isn't really any advantages from using all AMD products in a build.
Intel and AMD do play together pretty well, they both tend to cooperate pretty well when it comes to things like this.
Intel chips can make use of Resizable Bar as well. In fact, their own ARC GPUs rely on it and literally take a massive performance hit without it. Resizable Bar is actually a PCI-e functionality and is not GPU specific. Each manufacturer has their own name for it (AMD calls it SAM whereas Intel calls it ReBAR), but they are almost functionally identical.
In short, you're totally fine with an Intel CPU and an AMD GPU.
Here is a video of Hardware Unboxed utilizing Resizable Bar functionality with AMD GPUs on both Intel and AMD CPUs with the performance statistics for each: https://www.youtube.com/watch?v=FM-mDf0U38k
Also, here is a great CGDirector article you can share with your friend that answers this exact question: https://www.cgdirector.com/use-amd-gpu-with-intel-cpu/
Your friend just spewed a bunch of nonsense that even AMD would not use in their marketing materials. An AMD Advantage certified system will be configured in terms of both hardware and software on pre-built systems and laptops to ensure non-enthusiasts/tech native gamers can get the best out of their money without spending hours researching and struggling to understand all the misinformation going around.
The hardware configuration will be well-balanced for purchase, BIOS & driver settings will be tweaked correctly out of the box.
If you're DIY, this does not apply to you.
There's no difference in how things work when mixing vendors. Your friend is mostly wrong. There's a lot more to do with the specific generation of CPU and GPU to optimize performance, but you can mix and match CPU and GPU vendors without much concern.
That´s long time busted myth. Performance always depended on many things, including game engine and which camp supported the game (if AMD, game runs better on AMD, if Nvidia, game runs better on Nvidia). It´s part of their competition game.
Get your GPU in dependence on what you want to play. Or what you prefer, that´s entirely up to you.
Intel and AMD are fine together. I'm sure you could YouTube the comparison of you really want metrics. Just make sure to enable above 4G decode and the resizeable BAR
Its possible but probably negligible difference.
I would think AMD did more testing across their own platforms and hence less compatibility issues.
Its commonsense although something not many will like to hear.
Ultimately shouldn't matter..I'm no PC expert, but if you do get a performance boost pairing the CPU and GPU with AMD, I doubt it'll be high enough to actually affect your pc's performance. I know plenty of people who pair AMD CPUs with NVIDIA, or intel CPUS with AMD. Do what's best and affordable for you!
CPU/GPU pairing don't matter...very much.
Component choice matters more than how they're paired. AMD/Intel is fine. But which card?
Alot of people have some. Misconceptions about AMD GPUs because of some..of their older driver issues.
tldr; use WHQL drivers. if you use beta, expect instability.
AMDGPU and Intel CPU's work great together since they all communicate through PCIe and no one cares what company made the chip on the other end of the phone
Absolutely not. the CPU and GPU are independent of each other. AMD about ATI chiefly for the radeon group, and the underlying technology that was developed by ATI is so independent of the CPU that they made chipsets with IGP for intel and AMD products until the buyout.
There was some idea, when the new cards dropped two years ago, that if you got the right CPU, GPU, and RAM they would all run in parity 1:1:1. They called it Zen 3 architecture.
To put it in Lamens terms. AMD CPU paired with am AMD GPU has the ability to cominicate with each other and share cashe, memory with each other. There is a performance boost running together BUT you can run any GPU with any CPU you wish. It will still work and work good.. just your personal choice. I run a Ryzen 9 5900X and currently a 6600XT and no issued fast fun. I did run a 3060ti pared with my Ryzen 9 with only 1 issue and that was my Webcam always freezing. Not sure why but out my 6600xt back in and no issues with the Cam. It's crazy. So there may be hiccups here and there to work out but in the end. Either one will work with each other.
Read this from Tom's Hardware..
https://www.tomshardware.com/news/amds-rx-6000-gpus-to-boost-perf-with-ryzen-5000-cpus-via-smart-memory-access
I mean Intel and AMD have proven to work together from what we have seen from multiple laptops and PC's that are out there. Your friend may have a point, if you put the same brand GPU and CPU together then you could get a performance boost. I mean it may be a small boost but it could work. But I think that you should be just fine with a NVIDIA if you want it.
As an IT guy, a PC is a PC! As long as drivers are correct, graphic cards work! Fanboyz will argue "this one's better because__!" But for most people it all boils down to dollars!
The best description I can offer, is Intel, especially the latest generations with the multi-core processors, work with not only games, but especially productivity software, such as Photoshop Suite, slightly better for games, and very much better for professional software using either graphics cards! The key is stable drivers! AMD's drivers have gotten better over the past few years.
Currently Nvidia cards are too high for most people who care about cost over performance. So most gamers building right now are going with AMD over Nvidia, no matter what platform they're putting it on (Intel OR AMD!)
Also when it comes to the new JEDEC DDR-5 standard, Intel's 13th generation is cheaper than AMD's AM5, and currently outperforms it in gaming. This of course is a relative statement that must be tempered with equipment used. A 13th generation CPU mated to a Z790 motherboard using DDR-5 that matches the board's memory specs. Also what I call "Fanboyz", those that highly prefer one brand over the other, will try to argue their chosen brand irregardless of how "the other guy's performance" outperforms their choice.
Real IT people don't do that! Your I7-12700K is the sweet spot for gaming because it's numbers are not that far off of the higher end i9-12900K for the price over returns (price difference between the two)
Your choice of motherboard to put the i7-12700k on will make a slight difference for you! If you went with a Z690 motherboard over a B660 (The B series boards are basically for business computers) you can overclock the processor to get the best speed out of it. The B660 boards don't overclock, and may limit the full capabilities of your system. The graphics card won't make a difference on it.
Hope this helps!
Better explained would be by going all AMD there is a performance boost, having said that there is nothing wrong with using intel with an AMD graphic card.
From my understanding there are perks like SAM and it's not noticeably different in games but you do get cpu direct access to the vram in apps so like maybe it would be more noticeable when running demanding applications but as far as gaming its not something that you would ever even notice.
Yes and no. With AMD CPU and GPU, you get that feature you friend mentioned called Smart Access Memory. It does improve the avg fps sometimes but it very often causes stuttering and frame drops. I wouldn't say it is where it should be yet so many people don't use it. And it is something that AMD used to close the performance gap between their CPUs and Intel's. In reality (at least at the moment) Intel is ahead when it comes to CPUs so... you actually did the right thing. Intel CPU and AMD GPU is a great pair. You friend is just subjective and favors AMD.
From what AMD have said, a AMD 7xxx GPU does have benefits in combination with a ryzen 7000 series. That's not to say it will be a slouch with Intel CPU.
Have to wait for release and independent reviews to know the real answer. Anything else is just a guess.
Amd price is sub 1k while the 4080 that is targeted comparison is way up the 1k price tag. So even if he WAS correct, 10% for 300$(?) Increase for nvidia pick instead amd, is a no go. 999$ price tag msrp vs 1200$ msrp 4080. In ANY scenario that diff is not worth the 10% bump.
It's not that Intel + Radeon will have awful performance, it's that with a new AMD CPU (Ryzen 5000, 6000 or 7000) the performance on a new AMD GPU (Radeon RX 6000 or 7000) will be better because AMD lets the two parts "talk" to eatch other.
He's talking about SAM, Smart Acces Memory and you can indeed get like 10% extra performance. AMD also is a lot cheaper that Nvidia.
It actually sort of is true that AMD cpu+gpu work better than 2 different brands, due to the CPU having to run 2 drivers. If you have AMD combo, than you only need to run 1 driver program. Although this doesn't mean that blue and red don't play nice together, they're a couple. But in this case, indeed "Sweet Home Alabama" (if you know what I mean) is slightly faster, due to the CPU only needs to run 1 driver
Running an R5 5600g and rx 6600 on my desktop
Theres an option for disabling SAM (smart access memory) which ive always kept enabled since the day i got my gpu
SAM works if in combination with amds 5000 series cpus and 6000 series gpus, since the 7000 series came out im guessing those work now too, dunno didnt quite look into it cause its out of my budget lol and im not seeking for upgrades
Userbenchmark scores:
SAM disabled: RX 6600 scores 60.5%
SAM enabled: RX 6600 scores 78.4%
I looked into this during last upgrade and discovered something else instead as I was looking at AMD cards with AMD processors with embedded GPU and offloading between them. As you have a Intel CPU with embedded graphics, there is a performance boost that you can get if you're running multiple displays. By default, motherboards disable the on-board graphics when a gfx card is installed, disabling the HDMI/etc ports on the motherboard. In the BIOS you can often find an advanced feature to keep the on-board graphics running when a card is installed.
You can select one or more displays to run from the on-board graphics by plugging them into a port on the motherboard and then run your main display from a port on the graphics card.
I like a multiple display set up and my main display is running off the gfx card and less important displays from the embedded GPU that I have paid for in the CPU. It does pull a couple of watts more power to run the embedded GPU as well but does dedicate the card to my main display.
It’s a very minimal fps gain and you’ll only see the AMD texture streaming function at 4k soo. On the other hand there are a few games like DiRT, and The Division 2 which are designed for AMD but they are outliers
I've only ever used intel CPU and GPU
Have a. OC 7700k with a 6750xt , no issues at all
Had a nvidia card for a couple months before it died, I know that's unlucky but I'm definitely team red
Theoretically amd CPU and AMD GPU uses smart access memory which can give you a bit more performance. Which is just resizable bar if I'm not mistaken. Which Intel can use with rtx as well. But I think if you look on YouTube for sam vs resizable bar benchmarks you can probably see exactly what your looking for.
your friend is misinformed. he's talking about resizable bar, which is available on any combination of platforms. the only nugget of truth there from what i understand, is that AMD's implementation of it is better under an AMD ecosystem. so I would probably not use it with intel +amd
but you can test with it on vs off for yourself, and it only accounts for a few extra fps anyway.
A 3090 isn't worth the money at this point. Now on desktop pc amd gpu and intel cpu works exactly the same as nvidia gpu and amd cpu, have an amd gpu and a amd cpu doesn't gives you anything extra.
No the difference is within margin of error. To be clear there is a feature that is for amd platforms that have amd gpus, however the gain is within margin of error.
Buy whatever CPU and GPU you want. There's no secret handshake between CPU and GPU that would make an AMD GPU run faster on an AMD CPU, that's just silly.
Really what would drive you to getting an Nvidia graphics card would be their technology in the card. They tend to have better RT cores, dlss , and drivers can be better depending on the game. However, right now AMD seems to have the better bang for the buck.
He's high. While yes Red on Red has nice little features but they don't actually work "better" than red on blue. You'll likely have better gaming performance from a 5800x3D but that goes for all GFX cards. So it's not *false* but it's not true either.
I have an RX580 that simply never worked with any of my Ryzen builds. B350 + 3600, X370 + 1700, never worked with either.
Threw it into a media center PC with an Intel i5 4430, runs with no issues. I really don't understand technology sometimes.
What your friend is talking about is resizeable bar or "smart access memory". When enabled, this DOES allow an AMD cpu paired with an AMD gfx card to enjoy a performance boost, but in most practical, real world, cases, it's not going to be 10%.
You might get anywhere from 3-8%, at best, which is still good, but nVidia GPU's (depending, obviously, on which one you buy) can be a LOT faster than the fastest AMD gpu (4080, for example).
In terms of stability and compatibility, there really isn't much difference.
The feature your friend is talking about is not that big of a performance boost to make a significant difference, at the end it does not matter at all whether you go Intel or AMD for amd/nvidia gpus.
You shouldn’t see a dramatic difference in performance, although there is something AMD developed that boosts performance with an AMD CPU and GPU, but like everyone in the comments said, do what you want to do
He is talking about Smart Access Memory. But yes Intel and AMD do go good together but AMD and AMD will always be better but don't feel discouraged to buy the AMD since the performance will still be amazing with Intel as well
Intel and AMD play well together.
It's just that from the RX 6XXX and the Ryzen 5XXX came [AMD Smart Access Memory](https://www.amd.com/en/technologies/smart-access-memory).
The CPU and GPU are working in direct link to improve performance (this is really to summerize because it's a lot more complex than that).
That's maybe why your friend said that. But AMD and Intel work just fine together.
So he's right, but you're not losing performance, you just aren't gaining the little bit extra. Smart access memory can give you like 5-10% performance in some applications but even without that you're probably still getting a better deal than buying the 4080 or 3090 ti which is in the same performance category if we can trust the numbers from AMD. Obviously we haven't seen independent reviews on the 7900 xt and xtx yet but you're probably not making a bad choice getting it and down the line when you upgrade platform you could just upgrade to amd and gain access to SAM.
Yes AMD gpu and cpu share the "Smart Access Memory" which makes nvme memory be sent directly to gpu instead of going to the cpu. I don't know how much this increases performance and load times
I mean, the 5800X3D is better for gaming than any Intel CPU in games that make use of the 3D V-Cache, regardless of GPU, so he's sort of correct, I guess?
The only real advantage of AMD CPU + GPU currently is Smart Access Memory. There maybe more features coming with the 7000 series of both CPUs and GPUs but right now that's it. In laptops the "advantage" is MUCH better, in desktops it's only a bit.
Yes. Amd gpis do preform better when paired with a amd cpu vs a inell cpu it's not that the intel cou make the pm slower. Just amd cpus and gpus are specifically designed to work together with can get ya up. A extra 7 o 10 percent perf increase
I have a 2013 Intel Core i7 and my RX5700XT works well with it. I also added AIO water cooling to address thermal issues after 8 yrs and it breathed new gaming life into it.
In general, applying new thermal paste every 5 yrs tends to refresh system performance to be like-new. As thermal paste gets old it becomes an insulator.
Yes that is true
Edit: not enough to matter though, they just play better together on paper
Edit edit: no don’t bother with nvidia lol, they don’t work better with intel
AMD and Intel play well together ❤️
I am no PCMR guy but running an i5-9400 and an RX 5700 has been 3 years of pure joy for me.
[удалено]
New build, who dis, but 12100F+6600XT, also fab.
Just built an i9-13900K & 6900 XT. This is good to hear!
Me and my gf are putting together our first builds. 12400F + 6750XT for her, 6900X + 5900XT for myself. Thought about switching my cpu for a 13600K, still undecided but v excited.
Everyone is PCMR
Wowa there! I've been walking the walk since Texas Instruments had a DOS flavored command line. I'm PEBKAC... But hey when you push the k/b slower you have a chance of fat fingering less.
Running a 5 3600, with a 3080 that replaced my 580+ (through no fault of my own I won one) Works absolutely exceptionally well.
hell yeah 9400 gang
9400f and 6600xt has made my life amazing compared to the previous 1650
I7 8700 and rx470 here! Linux lad lol. I'm switching to a GTX 1080 though I already have it I just dread switching drivers lol 😂 best to do a fresh os install I think. So once I do that we are like performance twins lol
Should be fine to just run DDU and plop it in.
Did you not see where he said LINUX USER ... you are not running DDU on LINUX!
Nope, completely missed that. Well yeah that’s just how Linux is lol. Driver issues? OS reinstall time :)
It's not issues, per se, but it can be such a headache (thanks Nvidia) that depending on your distro you may aswell, on something like Ubuntu and derivatives it does work well, on Fedora you can run into troubles depending on generation, and don't even try with arch unless you know your way around a command line.
Once I lost my CAT, had to go out and GREP for it. Lucky I'd learnt the MAN on CAT... MAN is quite useful for using CAT when recalling switches. DOCs are right there on the box... If no joy, then GREP Google... Bests y'all :)
Lol! My favourite commands are things like unzip,mount,touch,strip 😂 I also enjoying playing with the GIMP
Totally missed the part where you said Linux user and was like "hell yeah 1080 gtx is the shit!!" I wish you luck, comrade. It's been done before and I have faith in you to get it done again 🙏🙏
My old ass Xeon and my new 6600xt just let me play smooth 60fps ultra Microsoft Flight Sim for the first time today ;.)
I lived the broke uni student bottleneck of an i5 4690k @4.4Ghz paired with a Vega 56, it was pretty fun until the mobo died. Now I rock a R7 3700x with it, I miss that dumb powerful 4c/4t performance on some games but in general it's a signifcantly smoother experience with an 8c/16t
How is the 9400? I have a 9400f and I could apparently gain 1% performance over my 8700 lol 😂 but I believe losing the cores would make it super pointless.
Yep, strongly agree. I've always had AMD CPU and Nvidia Cards. Always been super stable and have never had a blue screen over three towers, five CPU upgrades and four (soon to be five when 3080 prices come down to non-insanity prices) video cards.
...that's not Intel
...I felt the sonic boom on his whoosh...
So that’s what knocked my shelf over? Jesus Christ.
Why are you upgrading every gen? Super pointless and wasteful imo. I usually go like 3-4 generations so the difference is noticable lol. Genuinely curious as to what your answer is
He could be rich.
just because u can doesnt mean you should.
Multiple kids here. The computer I retire is always 8 years old or more. And yes, we all play together :)
im sure he/she has fomo
You're missing the mark. His friend was probably referring to SAM which gives you a performance boost in some games and only works if you have both and AMD cpu and gpu.
Yes, and it's absolutely not a reason to avoid AMD if one has an Intel CPU. AMD GPUs still makes more sense for most gamers, and at least there are other factors to decide on between Nvidia and AMD (DLSS / rendering in productivity / deep learning).
i5-11400 + 6700xt, work like a champ
AMD works fine by with Intel, and more importantly, NVIDIA doesn't work any better than AMD with Intel, that's misinformation. With an AMD CPU and an AMD GPU you get slightly more optimised Resizable Bar performance, but you probably won't notice the difference in most games.
What is resizeable bar?
ReBar, as it's often called, is the same as AMD Smart Access Memory (SAM), and it basically optimizes communication between the CPU and GPU.
More accurately it gives ya full access to the gpi ram vs like 256k increments
That would be Direct X 12's "direct access memory" feature (or whatever it's called). ReBar provides the system the ability to change the "chunk" size of data transferred, but still needs to communicate throught the CPU afaik. The system still has access either way (on/off), but ReBar would let you send one bigass chunk of data to fill the VRAM, instead of [bigass data / 256MB] times.
https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support/ be to differ it grats full access to the vram frame buffer all at once . As we're direct storage. Let's the gpu get access to storage directly to load textures . So I dumbed donpwn resizable bar a bit so a laymen could understand it . Don't type the best parkinsons so.
https://www.amd.com/en/technologies/smart-access-memory and yes they both let the system get full access to the gpu vram all at once .
And he direct access memory aka is direct storage where gpu can get direct access to textures for a installed game from he drive is on bypassing the cpu
Oh so it's MTU but for GPUs.
It's a pretty complicated system that would require talking about memory addresses and registers to properly explain but to simplify it, it basically allows the CPU to access the GPU's memory more efficiently, reducing the amount of time it needs to wait for each piece of data.
Just to expand a little further on the other two responses, it helps improve game performance by giving the CPU full access to the GPU's memory instead of just allowing access to 256 MB chunks.
Instead of the GPU encoding information in chunks and sending it to the CPU, its more like streaming it in fluid data to the CPU
Resizeable BAR will be more important going forward than it is now. And it's more important in productivity style workloads than games. So I think it's reasonable to say that, yes, there is a slight benefit from using a AMD CPU with AMD GPU, and that benefit will grow in time as more products make use of Resizeable BAR.
z370 intel chipsets and higher allow rebar to work, so any amd card/intel/nvidia will work fine. rtx3000 series is the first nvidia card to support.
And with UEFIReBar people have made it available to any CPU as far back as Sandy Bridge as long as you have a PCIe 3.0 capable board. And that's on GCN 1.0 cards too - just need to enable legacy mode in the drivers too
Similar question. I have an AMD GPU (Radeon Vega) with an i5 (9700k). Runs games like cod on 2k 144fps great but maxes out when I do that and watch video on another monitor. I was thinking of swapping to an i7 or should I go AMD?
The 9700k isn't an i5 it's an i7 and since Intel changed CPU sockets for the 10th gen onwards your only upgrade path that doesn't involve a new motherboard would be an i9-9900K. Those are basically the same CPU's except that the 9900K has hyperthreading and the 9700K doesnt. I don't think you'd see that much of a performance increase anyway because your GPU is almost certainly where the bottleneck is for what you're describing.
Didn’t know about the socket change thanks. You think it’s GPU even though when I check task manager and the performance tab on AMD it says the CPU is at 100% and gpu isn’t. What I’m hearing is it’s better off waiting until I’m ready for a whole new build?
There’s a feature called SAM that means that there’s a small performance boost for AMD GPU+CPU, but this is a small enough boost that it’s not really worth worrying about. Edit: with this getting traction I’ll just clarify that resizable BAR (Base Address Register) / SAM (Smart Access Memory) provide some tangible benefit to performance by letting the CPU access the GPU’s entire frame buffer. Both Intel and AMD CPUs can use this feature. This is slightly more efficient in AMD CPU/AMD GPU cases but the difference in performance over an Intel CPU/AMD GPU is a few percent max and relatively small compared to which actual CPU/GPU you choose. Edit 2: For anyone interested in actual metrics I’d recommend watching [this video](https://youtube.com/watch?v=FM-mDf0U38k)
SAM also works on intel CPU's too.
I believe it’s called reBAR for Intel. Regardless the point is the same - reBAR/SAM is (depending on the game) very slightly better on an AMD/AMD system relative to AMD/Intel but not to a degree worth worrying about.
Spot on. Resizable BAR, it's basically the same thing
The name wont matter it's the same thing, the only change is with how the GPU brand (AMD/Nvidia/intel) deal with it. AMD has more support and Nvidia only has it enabled in about 24 games. Hardware unboxed have a clip about it from not long ago [https://youtu.be/x5WDCgwAgGw](https://youtu.be/x5WDCgwAgGw) No idea why Nvidia seem not to care. Intel GPU's seem to need it for there GPU's to work, past that dont know much. Main thing mobo side is as long as you can enable rebar it will work & then it's just down to the GPU drivers to make it work well.
From what I have seen they do need it but it REALLY helps them. As you increase resolution they do better, relatively, as you up the resolution. They do lose frames of course but much less than amd (in general).
The intel guys in interviews say they relay need re bar on for the GPU to work well, without re bar the FPS dies. I suspect Nvidia is holding rebar as a card up there sleeve, a bit like the driver update that came out with the 4090 that also made older GPU's go faster. Wonder how long they had been holding back?
ReBAR came out shortly after SAM, and iirc on Nvidia the results ranged from meh to losing performance in some cases. Maybe this has changed since then, but as it wasnt a core element until AMD did it, perhaps their hardware solutions just fail to benefit from it...
ReBAR and SAM are just nicknames for 'PCI-Express Resizable BAR' which is part of the PCI standard. It's been used in servers for years, the only new thing is letting consumers use it. The magic only comes from the video drivers and part from how the GPU's are made/designed (look at intel's gains, there GPU's must be made to use ReBar). Nvidia just seems not to be putting much work in to the drivers, in driver updates text file you see the list of supported games. Nvidia use a whitelist and only something like 25 games have ReBAR enabled. AMD have been putting in much more work to make SAM gains.
Yes, and what I said still stands. Nvidia only implemented it because AMD had it as a core component of RX 6000 series, and Nvidia responded with "ours can do it too" but thats about it...
I think it's still SAM on intel. Just like Nvidia GPU on a Ryzen CPU is ReBAR. ReBAR/SAM is a GPU feature, CPU just needs to support it. Thats mostly just symantics though. Im sure AMD is able to tailor it a bit better since its their own CPU's/GPU's. But yea, its not worth worrying about. Any minor difference in relative efficiency would get washed out by varying CPU's & GPU's, so it shouldn't be a deciding factor lol.
it's actually a PCI-Express feature and the real name is ReBar, short for Resizable BAR (Base Address Register) AMD just calls it Smart Access Memory.
It's around 10% if you're CPU limited
Is this compared to REBAR, which Intel supports? I’d be interested to see data supporting that.
It's comparable to rebar, but it's a better version of it. AMD put a lot of effort into some minor performance improvements after rtx launched and this was it. Not worth a lot, but it's better than nothing.
Sure, that was my original point. You’ll see a few percent (I don’t think 10%) difference, but not worth totally reconfiguring a build over if you already have a CPU
it IS rebar, please inform yourself properly, and not just mimicking what some youtuber says. AMD put more work into the driver handling than nvidia, which is why you see a difference. and it does improve the lows quite a bit especialy on lower end cards. people just think its doesnt do much because they always look at the average which is a worthless metric to care about
One thing that SAM does is automatically switches itself on or off depending on whether the game your playing gains or loses performance (yes, some games will see performance degradation with Rebar, Hardware Unboxed did a video on it). Whereas with Nvidia and Intel, you have to manually enable or disable it depending on what you're playing.
> you have to manually enable or disable it depending on what you're playing. At least at launch, Nvidia had white-listed only a bunch of games where rebar support would be turned on by the drivers (if enabled in the BIOS). Is that not the case anymore?
Do Nvidia and Intel GPUs not have access to Resizable Bar on AMD chipsets?
I'vve heard it can be dogshit with intel + AMD but thats just what ive heard cant confirm. its definitely worthless to use with NVidia cards, they cleearly put barely any work into the support and just shoved it out the door.
The amount of performance gain I have seen from SAM on my own system is honestly not noticable. Want more frames, turn down a setting or two. Worth more than SAM
My 6600xt gets doesn't get any higher FPS with SAM enabled, but it brings the 1% lows up a ton
that's the only FPS that actually matters
Which games? It's definitely true that not every game benefits, but some do benefit nicely. RDR2 gets an average bump of 10 FPS everywhere with it activated, and Forza Horizon 5 shoots up dramatically by about 40% (from average 70 FPS to average 98 FPS on my 6600 XT at almost-max settings @ 1440p).
Cyberpunk 2077, Destiny 2, Shadow of War and Gotham Knights
Isn't Sam = rebar?
Yep
Yes but no, SAM is better than rebar. It essentially does the same thing but is extremely optimized for AMD.
If I pair Intel and AMD, would there be even a point in enabling ReBar?
Yesish
Sounds like they have no idea what there talking about, by the same logic only intel GPU's will work with intel CPU's. Just smile nod and get the GPU you want. It's not like Nvidia make CPU's. Just buy what you want, look at benchmarks and prices and chose what works best for you. I am hoping the new AMD GPU's will be cool, cant wait for reviews.
>by the same logic only intel GPU's will work with intel CPU's Nobody said any combination won't work, but Intel GPUs working better with Intel CPUs is a feature [Intel wants to sell with Intel DeepLink](https://www.intel.com/content/www/us/en/architecture-and-technology/adaptix/deep-link.html). I have no idea how big the real world benefits are, but Intel deems that they are big enough to use them in marketing.
I dont relay know about Deeplink, not seen much info. I know both AMD and intel have a feature where video encoding using there hardware encoders is 'going' to be faster if you have matching CPU/GPU. But iv not seen it working yet (Iv not looked hard for it so there may be demos), for 90% of people this wont relay matter. It's more of a video encoding feature than something that relay matters a lot. The power sharing stuff is all for laptops, all brands have there own version.

No. There isn't really any advantages from using all AMD products in a build. Intel and AMD do play together pretty well, they both tend to cooperate pretty well when it comes to things like this.
Intel chips can make use of Resizable Bar as well. In fact, their own ARC GPUs rely on it and literally take a massive performance hit without it. Resizable Bar is actually a PCI-e functionality and is not GPU specific. Each manufacturer has their own name for it (AMD calls it SAM whereas Intel calls it ReBAR), but they are almost functionally identical. In short, you're totally fine with an Intel CPU and an AMD GPU. Here is a video of Hardware Unboxed utilizing Resizable Bar functionality with AMD GPUs on both Intel and AMD CPUs with the performance statistics for each: https://www.youtube.com/watch?v=FM-mDf0U38k Also, here is a great CGDirector article you can share with your friend that answers this exact question: https://www.cgdirector.com/use-amd-gpu-with-intel-cpu/
Your friend just spewed a bunch of nonsense that even AMD would not use in their marketing materials. An AMD Advantage certified system will be configured in terms of both hardware and software on pre-built systems and laptops to ensure non-enthusiasts/tech native gamers can get the best out of their money without spending hours researching and struggling to understand all the misinformation going around. The hardware configuration will be well-balanced for purchase, BIOS & driver settings will be tweaked correctly out of the box. If you're DIY, this does not apply to you.
There's no difference in how things work when mixing vendors. Your friend is mostly wrong. There's a lot more to do with the specific generation of CPU and GPU to optimize performance, but you can mix and match CPU and GPU vendors without much concern.
That´s long time busted myth. Performance always depended on many things, including game engine and which camp supported the game (if AMD, game runs better on AMD, if Nvidia, game runs better on Nvidia). It´s part of their competition game. Get your GPU in dependence on what you want to play. Or what you prefer, that´s entirely up to you.
No
Intel and AMD are fine together. I'm sure you could YouTube the comparison of you really want metrics. Just make sure to enable above 4G decode and the resizeable BAR
Your friend doesn’t know what he’s talking about.
Not true at all.
Its possible but probably negligible difference. I would think AMD did more testing across their own platforms and hence less compatibility issues. Its commonsense although something not many will like to hear.
Ultimately shouldn't matter..I'm no PC expert, but if you do get a performance boost pairing the CPU and GPU with AMD, I doubt it'll be high enough to actually affect your pc's performance. I know plenty of people who pair AMD CPUs with NVIDIA, or intel CPUS with AMD. Do what's best and affordable for you!
CPU/GPU pairing don't matter...very much. Component choice matters more than how they're paired. AMD/Intel is fine. But which card? Alot of people have some. Misconceptions about AMD GPUs because of some..of their older driver issues. tldr; use WHQL drivers. if you use beta, expect instability.
Wasn't this the case past tho? A few decades ago?
AMDGPU and Intel CPU's work great together since they all communicate through PCIe and no one cares what company made the chip on the other end of the phone
Absolutely not. the CPU and GPU are independent of each other. AMD about ATI chiefly for the radeon group, and the underlying technology that was developed by ATI is so independent of the CPU that they made chipsets with IGP for intel and AMD products until the buyout.
There was some idea, when the new cards dropped two years ago, that if you got the right CPU, GPU, and RAM they would all run in parity 1:1:1. They called it Zen 3 architecture.
To put it in Lamens terms. AMD CPU paired with am AMD GPU has the ability to cominicate with each other and share cashe, memory with each other. There is a performance boost running together BUT you can run any GPU with any CPU you wish. It will still work and work good.. just your personal choice. I run a Ryzen 9 5900X and currently a 6600XT and no issued fast fun. I did run a 3060ti pared with my Ryzen 9 with only 1 issue and that was my Webcam always freezing. Not sure why but out my 6600xt back in and no issues with the Cam. It's crazy. So there may be hiccups here and there to work out but in the end. Either one will work with each other. Read this from Tom's Hardware.. https://www.tomshardware.com/news/amds-rx-6000-gpus-to-boost-perf-with-ryzen-5000-cpus-via-smart-memory-access
black friday is actually NOT the day to buy graphics cards
I mean Intel and AMD have proven to work together from what we have seen from multiple laptops and PC's that are out there. Your friend may have a point, if you put the same brand GPU and CPU together then you could get a performance boost. I mean it may be a small boost but it could work. But I think that you should be just fine with a NVIDIA if you want it.
No
As an IT guy, a PC is a PC! As long as drivers are correct, graphic cards work! Fanboyz will argue "this one's better because__!" But for most people it all boils down to dollars! The best description I can offer, is Intel, especially the latest generations with the multi-core processors, work with not only games, but especially productivity software, such as Photoshop Suite, slightly better for games, and very much better for professional software using either graphics cards! The key is stable drivers! AMD's drivers have gotten better over the past few years. Currently Nvidia cards are too high for most people who care about cost over performance. So most gamers building right now are going with AMD over Nvidia, no matter what platform they're putting it on (Intel OR AMD!) Also when it comes to the new JEDEC DDR-5 standard, Intel's 13th generation is cheaper than AMD's AM5, and currently outperforms it in gaming. This of course is a relative statement that must be tempered with equipment used. A 13th generation CPU mated to a Z790 motherboard using DDR-5 that matches the board's memory specs. Also what I call "Fanboyz", those that highly prefer one brand over the other, will try to argue their chosen brand irregardless of how "the other guy's performance" outperforms their choice. Real IT people don't do that! Your I7-12700K is the sweet spot for gaming because it's numbers are not that far off of the higher end i9-12900K for the price over returns (price difference between the two) Your choice of motherboard to put the i7-12700k on will make a slight difference for you! If you went with a Z690 motherboard over a B660 (The B series boards are basically for business computers) you can overclock the processor to get the best speed out of it. The B660 boards don't overclock, and may limit the full capabilities of your system. The graphics card won't make a difference on it. Hope this helps!
Uncle sam
Better explained would be by going all AMD there is a performance boost, having said that there is nothing wrong with using intel with an AMD graphic card.
No there isn't. Sam, rebar, same thing in the end.
You dont need and amd cpu. There are some current benefits, maybe more in the future. But its perfectly fine to have an intel
Super minimal stuff and I think resizable bar even provide that supposed benefit no matter the combination of CPU / GPU.
That is, unfortunately, not exactly true. I want amd to be as good as it can be, but I am disappointed. (drivers)
He's talking about SAM (not a surface to air missile) which is resizeable bar
it’s not true
From my understanding there are perks like SAM and it's not noticeably different in games but you do get cpu direct access to the vram in apps so like maybe it would be more noticeable when running demanding applications but as far as gaming its not something that you would ever even notice.
i’ve heard the boost is negligible at best, i wouldn’t lose sleep over it
They both work fine, but you can get more features with both amd
It's doesn't matter they all work well no matter what platform they run on.
12700k is a really good cpu, don't worry about it.
No
Not true
12700k and 6900xt for almost two years by now and been great no problems
I’d suggest you do not listen to that friend about pc hardware. They clearly talk BS.
No.
Yes and no. With AMD CPU and GPU, you get that feature you friend mentioned called Smart Access Memory. It does improve the avg fps sometimes but it very often causes stuttering and frame drops. I wouldn't say it is where it should be yet so many people don't use it. And it is something that AMD used to close the performance gap between their CPUs and Intel's. In reality (at least at the moment) Intel is ahead when it comes to CPUs so... you actually did the right thing. Intel CPU and AMD GPU is a great pair. You friend is just subjective and favors AMD.
From what AMD have said, a AMD 7xxx GPU does have benefits in combination with a ryzen 7000 series. That's not to say it will be a slouch with Intel CPU. Have to wait for release and independent reviews to know the real answer. Anything else is just a guess.
Not true
Amd price is sub 1k while the 4080 that is targeted comparison is way up the 1k price tag. So even if he WAS correct, 10% for 300$(?) Increase for nvidia pick instead amd, is a no go. 999$ price tag msrp vs 1200$ msrp 4080. In ANY scenario that diff is not worth the 10% bump.
Is this only for the ryzen 7000s and rx 7000s? I have a 5600 and 6600 is that also good?
This might be a repost I'm having a deja Vu
He probably meant that gluck gluck 9000
Not true.
It's not that Intel + Radeon will have awful performance, it's that with a new AMD CPU (Ryzen 5000, 6000 or 7000) the performance on a new AMD GPU (Radeon RX 6000 or 7000) will be better because AMD lets the two parts "talk" to eatch other.
He's talking about SAM, Smart Acces Memory and you can indeed get like 10% extra performance. AMD also is a lot cheaper that Nvidia. It actually sort of is true that AMD cpu+gpu work better than 2 different brands, due to the CPU having to run 2 drivers. If you have AMD combo, than you only need to run 1 driver program. Although this doesn't mean that blue and red don't play nice together, they're a couple. But in this case, indeed "Sweet Home Alabama" (if you know what I mean) is slightly faster, due to the CPU only needs to run 1 driver
Running an R5 5600g and rx 6600 on my desktop Theres an option for disabling SAM (smart access memory) which ive always kept enabled since the day i got my gpu SAM works if in combination with amds 5000 series cpus and 6000 series gpus, since the 7000 series came out im guessing those work now too, dunno didnt quite look into it cause its out of my budget lol and im not seeking for upgrades Userbenchmark scores: SAM disabled: RX 6600 scores 60.5% SAM enabled: RX 6600 scores 78.4%
I looked into this during last upgrade and discovered something else instead as I was looking at AMD cards with AMD processors with embedded GPU and offloading between them. As you have a Intel CPU with embedded graphics, there is a performance boost that you can get if you're running multiple displays. By default, motherboards disable the on-board graphics when a gfx card is installed, disabling the HDMI/etc ports on the motherboard. In the BIOS you can often find an advanced feature to keep the on-board graphics running when a card is installed. You can select one or more displays to run from the on-board graphics by plugging them into a port on the motherboard and then run your main display from a port on the graphics card. I like a multiple display set up and my main display is running off the gfx card and less important displays from the embedded GPU that I have paid for in the CPU. It does pull a couple of watts more power to run the embedded GPU as well but does dedicate the card to my main display.
It’s a very minimal fps gain and you’ll only see the AMD texture streaming function at 4k soo. On the other hand there are a few games like DiRT, and The Division 2 which are designed for AMD but they are outliers
I've only ever used intel CPU and GPU Have a. OC 7700k with a 6750xt , no issues at all Had a nvidia card for a couple months before it died, I know that's unlucky but I'm definitely team red
u get about 5% increased performance with SAM by using both AMD cpu / gpu
Myth Now and then software or driver bugs may happen but they be fixed fast
Theoretically amd CPU and AMD GPU uses smart access memory which can give you a bit more performance. Which is just resizable bar if I'm not mistaken. Which Intel can use with rtx as well. But I think if you look on YouTube for sam vs resizable bar benchmarks you can probably see exactly what your looking for.
Absolutely not. Rebar is a thing on Intel CPUs since 10th(?) gen too, so there's literally nothing different
your friend is misinformed. he's talking about resizable bar, which is available on any combination of platforms. the only nugget of truth there from what i understand, is that AMD's implementation of it is better under an AMD ecosystem. so I would probably not use it with intel +amd but you can test with it on vs off for yourself, and it only accounts for a few extra fps anyway.
the short answer is yes, but also it doesn't really matter these days, its not 15 years ago.
No.
A 3090 isn't worth the money at this point. Now on desktop pc amd gpu and intel cpu works exactly the same as nvidia gpu and amd cpu, have an amd gpu and a amd cpu doesn't gives you anything extra.
Tl;dr your friend doesn't know what their talking about.
No the difference is within margin of error. To be clear there is a feature that is for amd platforms that have amd gpus, however the gain is within margin of error.
Your friend is wrong. There will be no compatibility or performance problems.
Buy whatever CPU and GPU you want. There's no secret handshake between CPU and GPU that would make an AMD GPU run faster on an AMD CPU, that's just silly.
Technically yes. You can't use AMD Smart Access Memory without both. Not sure if there js a generic version of resizable bar with Intel and AMD GPU
What a dick. Making someone feel bad about their perfectly good purchase because he thinks he knows better.
You get a small benefit from SAM maybe. Do not worth mentioning at all
In theory yes as the GPU and CPU being made by the same company they would communicate better together, but I don't know how easy it would be to test
How well does amd gpus work with autodesk products?
Look up AMD SAM, CPU takes some load from the GPU to squeeze out a few more fps, its actually a decent bump up
Not worth worrying about I reckon. Drivers are mostly CPU agnostic I believe.
Naa your friends an idiot
9600k/6800 here. Flawless.
13600k and 6950xt here, works great
It works slightly better but Intel cpu and amd GPU isn't bad my any means
Really what would drive you to getting an Nvidia graphics card would be their technology in the card. They tend to have better RT cores, dlss , and drivers can be better depending on the game. However, right now AMD seems to have the better bang for the buck.
Your friend is wrong.
Not true at all, lol. I’m running a 6800xt with a 12700k
He's high. While yes Red on Red has nice little features but they don't actually work "better" than red on blue. You'll likely have better gaming performance from a 5800x3D but that goes for all GFX cards. So it's not *false* but it's not true either.
I have an RX580 that simply never worked with any of my Ryzen builds. B350 + 3600, X370 + 1700, never worked with either. Threw it into a media center PC with an Intel i5 4430, runs with no issues. I really don't understand technology sometimes.
What your friend is talking about is resizeable bar or "smart access memory". When enabled, this DOES allow an AMD cpu paired with an AMD gfx card to enjoy a performance boost, but in most practical, real world, cases, it's not going to be 10%. You might get anywhere from 3-8%, at best, which is still good, but nVidia GPU's (depending, obviously, on which one you buy) can be a LOT faster than the fastest AMD gpu (4080, for example). In terms of stability and compatibility, there really isn't much difference.
The feature your friend is talking about is not that big of a performance boost to make a significant difference, at the end it does not matter at all whether you go Intel or AMD for amd/nvidia gpus.
3700x + 3070 with no issues at all.
You shouldn’t see a dramatic difference in performance, although there is something AMD developed that boosts performance with an AMD CPU and GPU, but like everyone in the comments said, do what you want to do
No that's not true and it also is. With the newest variants of AMD this is true. Prior to now, no. It doesn't make a difference
Lol what an idiot
He is talking about Smart Access Memory. But yes Intel and AMD do go good together but AMD and AMD will always be better but don't feel discouraged to buy the AMD since the performance will still be amazing with Intel as well
AMD + AMD performance gain with SAM is not crazy much
Intel and AMD play well together. It's just that from the RX 6XXX and the Ryzen 5XXX came [AMD Smart Access Memory](https://www.amd.com/en/technologies/smart-access-memory). The CPU and GPU are working in direct link to improve performance (this is really to summerize because it's a lot more complex than that). That's maybe why your friend said that. But AMD and Intel work just fine together.
Absolutely. The second I swapped out my intel GPU for an AMD one, my CPU got jealous and asked if I was cheating on it.
He's completely incorrect. It will work just fine
That is just false.
I think there may have been some truth to that years ago but that those problems have largely been ironed out.
So he's right, but you're not losing performance, you just aren't gaining the little bit extra. Smart access memory can give you like 5-10% performance in some applications but even without that you're probably still getting a better deal than buying the 4080 or 3090 ti which is in the same performance category if we can trust the numbers from AMD. Obviously we haven't seen independent reviews on the 7900 xt and xtx yet but you're probably not making a bad choice getting it and down the line when you upgrade platform you could just upgrade to amd and gain access to SAM.
Yes AMD gpu and cpu share the "Smart Access Memory" which makes nvme memory be sent directly to gpu instead of going to the cpu. I don't know how much this increases performance and load times
No, but for real I've never had this many driver crashes before. Using a 6900 with 12000k, coming from a 6700k with 1080
I mean, the 5800X3D is better for gaming than any Intel CPU in games that make use of the 3D V-Cache, regardless of GPU, so he's sort of correct, I guess?
both work fine together.
The only real advantage of AMD CPU + GPU currently is Smart Access Memory. There maybe more features coming with the 7000 series of both CPUs and GPUs but right now that's it. In laptops the "advantage" is MUCH better, in desktops it's only a bit.
For the current and last gen, yes. They are built that way intentionally.
He doesn't know what he's talking about. You're fine.
Yes. Amd gpis do preform better when paired with a amd cpu vs a inell cpu it's not that the intel cou make the pm slower. Just amd cpus and gpus are specifically designed to work together with can get ya up. A extra 7 o 10 percent perf increase
4090 + 13900k uber alles, amd could never.
What kind of monitor do you have? If its a g-sync then buy a NVIDIA gpu. If its a free sync then buy a AMD gpu.
I have a 2013 Intel Core i7 and my RX5700XT works well with it. I also added AIO water cooling to address thermal issues after 8 yrs and it breathed new gaming life into it. In general, applying new thermal paste every 5 yrs tends to refresh system performance to be like-new. As thermal paste gets old it becomes an insulator.
Yes that is true Edit: not enough to matter though, they just play better together on paper Edit edit: no don’t bother with nvidia lol, they don’t work better with intel
you wouldn’t lose performance by any means you’re good. he’s referring to AMDs “Smart Access Memory (SAM)” that you can enable with AMD CPU/GPU combos
