What do AMD GPUs do better than Nvidia GPUs?

[_Cereal_]

good thread to spot the fanboys (from both sides), personally I am using NV card now but i really liked the sharpening feature on my old 5700 XT card, always thought the image looked crisper on AMD cards but might just be my eyes/monitor,
unless we are only specifically talking about the higher end cards i will have to say Vram, 3070 is already struggling on Doom eternal even at 1440p (since the raytracing update) so i dont think is something that anyone looking into buying a GPU should ignore, specially when they go easily for over 500 quid, AMD seems to be ahead of the curve and most of their cards will 100% age better because of this (3090 and 3080TI being exceptions for obvious reasons)

Nope, not just you. I upgraded from a 1080ti to a 6900 xt last week and the image is definitely sharper / colours "pop" more on the 6900 xt.

I am currently sitting on the fence and cant decide whether to get 6700xt or 3070 at this point. Obviously the RTX element of the 3070 is a more robust solution for Ray Tracing but the more VRAM and comparable rasterised performance in games cant be ignored + the fact the 6700XT is around 2-300 cheaper at present.

Either way its a decent improvement in noise, heat and performance from the VII across the board.....but what to do!

300 quid difference i would absolutely go AMD, if anything put 300 on top of that 6700xt price and look for a 6800 xt instead?

Trying not to be too hasty on purchasing as the pricing is all over the place as we all know and the 6700xt prices seem to be slowly lowering at present. Also would hate to buy and then Gibbo does another forum deal for £500 or so on a 6700xt. Holding out and going that 6800xt route might be an option if prices come down a little. This will be the biggest GPU spend I have ever done so quite nerve racking lol

Seeing as AMDs raybtracing isn’t hardware based would it not also make sense that this can improve more than Nvidias ray tracing without needing to upgrade?

I did think the same thing but my knowledge on the topic isn't extensive being honest

I have all 3, Radeon 7, 6800xt Nitro+ and 6700xt Nitro+... trust me get the 6800xt. Performance improvements are also not across the board, in games yes.. In other areas not in the slightest in fact it's massively slower in opencl compute than a 7, 7 was a compute card re-purposed all the good compute stuff is just not there in Navi.

I noticed this day one with my 6800xt when I was compiling some opencl and my system tanked and was just a bit more laggy than its normal snappy self. You never noticed it on VII because of the mental amounts of memory bandwidth. I'll be honest this has got a lot better since I updated drivers a while back.

Either way I'm sure fp32 and fp64 (double precision) is still way faster on VII than it is 6800xt. Certainly fp64 loads are at least twice as fast.

Going from a VII to a 6700 XT makes no sense tbh, they're very close in performance; tho I do understand you can sell the VII for a lot more. A 3070 makes slightly more sense because it's faster than that again, but also has a bunch of other features you wouldn't get from a 6700 XT (or other AMD GPUs). Personally I got a 6800, and while I got it for MSPR and can use the extra vram more than the RTX, I'd still go Nvidia if I could do it over again. I was cheap, decided not to pay over MSRP at launch (wanted the 3080) and played the waiting game - oopsie daisy. Didn't get completely screwed, clearly, but still didn't feel as good as it should've.

Say what? AMD's implementation is hardware based in a similar way to NV's. There is a one RA (Ray accelerator) per compute unit at the end of the graphics pipeline this capture of one of the amd slides shows this:



And a quote from amd engineering labs re RDNA 2:

"Measured by AMD engineering labs 8/17/2020 on an AMD RDNA 2 based graphics card, using the Procedural Geometry sample application from Microsoft’s DXR SDK, the AMD RDNA 2 based graphics card gets up to 13.8x speedup (471 FPS) using HW based raytracing vs using the Software DXR fallback layer (34 FPS) at the same clocks. Performance may vary. RX-571"

So yes RDNA2 has one RA per compute unit so a 6800xt has 72 RA's.

I thought I had watched in other places that is wasn’t.

It's weird as you are the 2nd person to say the 6700xt is not that much faster than the VII but in reviews it seems pull away quite considerably where you are looking at 30 FPS improvement at 1440p in things like BF5, Doom Eternal and across techpowerups review it was 35+ FPS faster across the board of all of their tests. Of course on top of that you have the lower power consumption (not tricky of course lol) and noise with something like the TUF version + there is ray tracing support and SAM being so I have a 5600x for a potential extra boost. Also comes VERY close to the 3070 of course without RT on.

It's faster in games there is no doubt, but in my experience.. 6800xt... Going from a 7 its the only option if you stick AMD and dont hate your wallet.

I wouldn't trust where you saw that then.

The wallet does have limited stretch in it lol. Like most I think at the moment.

Think it's just time to hunker down and hope that prices stabilise a bit for a while then. Not as though my machine is slow at present of course

What I can tell you is that the nitro+ cards are soooooo much quieter than 7, I mean its ridiculous. They are quieter under load than 7 is idle

The 6800xt does have two more heat pipes than the 6700xt does. The 6800xt is also quite a lot faster, noticeably so in everything really. My 6700xt is still in it's box and the 7 is in the wifes machine 6800xt in mine.

I did notice with cyberpunk that AMD RT performance improved with every patch & driver update, starting off at a basically unplayable ~11-15fps when it was first added, to a consistent passable 30 with no other settings changed

Ha nice to know from an owner of both cards, the VII can get a bit loud when she fancies it but I am running undervolted so it's not too bad at all overall.

Yeah the dream would be a nitro+ 6700/6800 as look really, really lovely but I missed the boat completely on the forum deal

A 6700xt nitro went for £500 in a wanted thread a few days back, need to keep a look out and see if any more pop up as unlikely as that will be I should imagine. You get bored of looking at yours let me know

Not looking to eBay my VII which limits my £££ to spend but it's probably going to a local forum member for sensible money as would rather help him out than feed the mining crazy

I guess it is one of the those things, the AMD driver techs are still hugely in the infancy with RT vs. NV who have invested monster amounts of time and money into RTX and the results definitely show. Be interesting to see where things in six months

There is some evidence that ray tracing on AMD (it is hardware based though) has improved since launch. I doubt if it will be improved enough to catch-up with NVIDIA however.

Not that anyone cares about raytracing though
