6800xt v 3080 VR specific benchmarks

[Shortyuk]

Hi All,

 

Thought this might be of interest, while not DCS specific (or at all) its the only VR specific benchmark's I have seen so far comparing the two GPUS.

It looks like the 3080 performs better in general (11 out of 15 VR games tested), which sort of mirrors the 4K performance results as VR tends to render beyond 4K resolution.

 

Would’ve been nice to see the actual DCS results, though.

Hm, so sounds like the 3090 is still the top of the heap, the 6800xt is AMD's best right?

[Lurker]

AMD is releasing the 6900XT which should be much cheaper than the 3090. I would really like to see a 6800XT benchmark in DCS World. Im considering that card, but now that I've seen real world benchmarks, it appears that it is indeed behind the 3080, despite being better in synthetic benchmarks or "on paper".

Wrong :) 6900XT is the fastest card and, with DCS, it perform better then 3090, there is a leak of a user in the forum (Aurelius)

 

SAM adds about 2 to 5% depending upon some preset parameters. (On average, it is about 2.4%.) In beta DCS as of tonight, the RX 6900 XT is 2.3% faster in VR with the G2 than the 3090. Granted, not much, but then the 6900 XT is likely to be $700 or so cheaper! Even if Nvidia improves their drivers and the 3090 pulls ahead by say, 4%, that is 4% for $700.

 

No, because if you install the 6900 XT on an Intel 10900K + Z490 board system, you will get equal FPS performance with respect to the RTX 3090 but with slightly better visuals for at least $750 less. (Actually, right now, it is most likely going to be closer to $1000 less.)

 

Excellent question Exil. We have one 6800 XT in the lab, but we do not primarily use our GPUs for gaming of course (we use them for ML computation and ANN simulation). One of the guys was goofing off after hours with it and DCS, but I do not recall off the top of my head how it performed. I do have personal experience with DCS and the Reverb G2 in conjunction with the 6900 XT. What I can say without drawing heat from AMD's legal department is that a full AMD system (Ryzen 9 5950X - X570 board - 6900 XT) performs better and ever so slightly faster in VR than an Intel 10900K - Z490 - RX 3090 platform. This time around AMD has not only caught up to but slightly surpassed Intel.

I sold an unopened 3080 I bought and am planning to buy 6900XT, hopefully for the same price I got from the 3080. My understanding is that the 6900XT is really fast and can be overclocked pretty well and should be quite good for an obsolete game engine like DCS. Note that most of the 3080/6800 tests use DX12 games. I imagine that would make them more 3080 friendly.

 

My optimistic hopes are that by the middle of 2021 I can buy a 6900XT for only $300 more than retail price and maybe in spring 2022 my HP Reverb G2 that I pre-ordered in August arrives... I heard AMD already made 7 6900XT cards and 8th one is being made and will be boxed by the end of the year.

Id take that information posted with a pinch of salt.

Yes of course, but stop thinking that nvidia is the only choice for best performance. Consider also that the user in question has already proved reliable in the past

[Harlikwin]

Yeah, its not like I can buy any of these cards at this point, so I have time to let the actual reviews roll in. But it sounds like you need a PCIE 4 board/AMD proc for the 6900xt to work well, which, in my context I don't have. I'd like to see the XT in Z390 board.

From what I am seeing today the Red team is probably the way to go on a new build.

Seeing some reports with another sim folks being able to run without reprojection kicking in.

If I were to build a new rig today I would be giving AMD a very strong and hard look.

[Harlikwin]

Problem is im not looking at building from scratch. Im just looking at the vidcard.

[tigger6]

 

lol

 

I meant middle of 2021 of course. I'm not that optimistic.

 

And stop laughing! Baking silicon wafer is no child's play. I tried baking them in my oven a dozen times now and nothing useful is coming out. Always looks like a pizza and my kids eat it. Maybe I should put less flour in.

 

Locally there are great news about the 6800xt custom design cards. You will be able to preorder them! Like - they don't know if or when they would ship, nobody has seen one yet, and the official statement is that you'd have to be an optimist to think you'll see them this year..

[Lurker]

Same here. Too bad no one dedicated to testing in DCS has demonstrated how the 6800XT performs vs the 3080 so far. I have a decent rig, a 9600K I can easily push to 5Ghz, a good SSD drive, 32GB or RAM, and I need a card that can consistently perform well in VR.

 

One thing that's drawing me back to 3080 is that I dont' ONLY game in DCS, I will be deep in Cyberpunk 2077 when it ships, and I do like the way it looks using Ray Tracing. (Cyberpunk will not be supporting Raytracing with AMD cards)

[Lurker]

I also got a few emails asking about 6900 XT performance on the Intel 10900K - Z490 platform vs the RTX 3090. I can't tell you yet with exact details about that because neither one of our 6900 XT cards is being used for gaming much. (We do artificial neural network simulation) That said, I am going to take an intelligent guess and say that if you plug the 6900 XT into a top line Intel system, it will be within the RTX 3090 by plus/minus two or three percent, and in conjunction with the Reverb G2.

 

(No, ... I am not testing either card with the Facebook Quest 2 because I don't like how they have helped to fuel conspiracy theories that are flat out bull#$@!.)

 

Do you have any information regarding how the 6800XT performs compared to the 3080RTX? I think that the NDA should be lifted on the reference 6800XT cards now?

[Lurker]

Sorry Lurker, ... no I do not. We have one RTX 3080 in our lab, but I have not personally used it, nor does that machine have DCS installed on it. I thought one of the other guys had used it with DCS, but I found out that he did not. Sorry.

 

No worries. Someone is bound to do a test at some point in the future I guess.

Let's not forget Nvidia itself stated in the 1st place that 3090 it's not a gaming GPU while RX6900XT is.

RTX3090 it's basically a titan and it's not meant for gaming.

Yeah I have an EVGA 3090 FTW3 Ultra, and whilst I don't necessarily regret the purchase I would advise folks that it is really not

worth the cost to get it for what we do. I would go either 3080 or with one of the new Ryzen offerings, 6800xt or 6900xt. If you are concerned about the only 10 GB of vram of the 3080's then either the Ryzen offerings or wait for maybe a new 3080 variant like a Ti.

there we compared those two with a pimax.

Nicely done!!!

I’m not sure testing on a device that is cpu bottlenecked is helpful...

Are you referring to JayRoc's tests? Those shouldn't be CPU bottlenecked at all having a 5900/5600 processor.

I dont know what Pimax they used, but when I do DCS with my 8KX, the CPU has a walk in the park, and the 3090 really work to make up the cost of it.

My apologies, I misread the article

As written, it was a Pimax 8KX. We did way more testing than showed there. There are some results that dont fit and we have to verify them, but nothing shows at this moment that

the 5600x nor the 5900x are limiting the performance. Next week we will test a lot more...different RAM setups and older hardware for comparison.
