Ashes of the Singularity Revisited: A Beta Look at DirectX 12 & Asynchronous Shading
by Daniel Williams & Ryan Smith on February 24, 2016 1:00 PM ESTDirectX 12 Single-GPU Performance
We’ll start things off with a look at single-GPU performance. For this, we’ve grabbed a collection of RTG and NVIDIA GPUs covering the entire DX12 generation, from GCN 1.0 and Kepler to GCN 1.2 and Maxwell. This will give us a good idea of how the game performs both across a wide span of GPU performance levels, and how (if at all) the various GPU generational changes play a role.
Meanwhile unless otherwise noted, we’re using Ashes’ High quality setting, which turns up a number of graphical features and also utilizes 2x MSAA. It’s also worth mentioning that while Ashes does allow async shading to be turned off and on, this option is on by default unless turned off in the game’s INI file.
Starting at 4K, we have the GeForce GTX 980 Ti and Radeon R9 Fury X. On the latest beta the Fury X has a strong lead over the normally faster GTX 980 Ti, beating it by 20% and coming close to hitting 60fps.
When we drop down to 1440p and introduce last-generation’s flagship video cards, the GeForce GTX 780 Ti and Radeon R9 290X, the story is much the same. The Fury X continues to hold a 10fps lead over the GTX 980 Ti, giving it an 18% lead. Similarly, the R9 290X has an 8fps lead over the 780 Ti, translating into a 19% performance lead. This is a significant turnabout from where we normally see these cards, as 780 Ti traditionally holds a lead over the 290X.
Meanwhile looking at the average framerates with different batch count intensities, there admittedly isn’t much remarkable here. All cards take roughly the same performance hit with increasingly larger batch counts.
Finally at 1080p, with our full lineup of cards we can see that RTG’s lead in this latest beta is nearly absolute. The 2012 flagship battle between the 7970 and the GTX 680 puts the 7970 in the lead by 12%, or just shy of 4fps. Elsewhere the GTX 980 Ti does close on the Fury X, but RTG’s current-gen flagship remains in the lead.
The one outlier here is the Radeon R9 285, which is the only 2GB RTG card in our collection. At this point we suspect it’s VRAM limited, but it would require further investigation.

You don't have enough data to know this.Once the second generation of DX12 cards come out, then you can analyze the jumps and get a better idea. Ideally you'd wait for three generations of post-DX12 GPUs to get the full picture. As it is, all we know is that AMD's DX12 driver is better than their DX11 driver... which ain't saying much.

except we have 3 generations of DX12 cards already on AMD's side, starting with the hd7970, which still holds its own quit well.and we've had multiple DX12 and vulkan benchmarks already and in every one of them the 290 and 390 in particular beat the crap out of nvidia's direct competition. in fact they often beat or match the card above them as well
as for drivers. AMD's dx11 drivers are fine. they just didn't invest bucketloads of money in game specific optimizations like nividia did, but instead focused on fixed the need for those optimizations in the first place. nvidia's investment doesn't offer long term benefits (a few months, then people move on to the next game) and that level of optimization in the drivers is impossible and even unwanted in low level API's.
basically nvidia will be losing its main competitive advantage this year.

I think what he meant was we don't have enough test cases to conclude mature dx12 performance. The odds are pointing to AMD having faster gpus for dx12. But until multiple games are out, and preferably one or two "dx12" noted driver, we're speculating. I thought this was clear from the article?It's a stretch calling 3 generations of dx12 released cards too. I guess if we add up draft revisions there are 50 generations of AC wireless.
You could state that because AMDs arch is targeting dx12, it looks to give an accross the board performance win in dx12 next gen games. But again we only have 1 beta game as a test case. Just wait and it will be a fact or not. No need to backfill the why

Right, they didn't invest bunchload in optimizing current game, they just payed a single company to make a benchmark game using their most strong point in DX12, super mega threaded (useless) engine. Not different than nvidia using super mega geometry (uselessly) complex scenes helped by tessellation.Perfect marketing: most return with less investments.
Unfortunately a single game with a bunchload of ASYN compute thread added just for the joy of it is not a complete DX12 trend: what about games that are going to support Voxel global illumination that AMD HW cannot handle?
We'll see where the game engine will point to. And if this is another faux-fire that AMD has started up these years seeing they are in big trouble.
BTW: it is stupid to say that 390 "beat up the crap aout of anything else" that is using a different API. All you could see is that a beefed up GPU like Hawaii consuming 80+W with respect to the competition manage finally to pass it as it should have do at day one. But this was only because of the use of a different API with different capacities that the other GPU could not benefit from.
You can't say it is better if with current standard API (DX11) that beefed up GPU can't really do better.
If you are so excited by the fact that a GPU 33% bigger than another is able to get almost 20% more in performance with a future API and best conditions at the moment a complete new architecture is going to be launched by both red and green teams, well, you really demonstrates how biased you are. Whoever has bought a 290 (then 390) card back in the old days during all these month has been biting dust (and loosing Watts) and the small boost at the end of these cards life is really a shallow thing to be exited for.

I like what AMD has done with "future proofing" their cards and drivers for DirectX12. But people buy graphics cards to play games TODAY. I'd rather get a graphics card with solid performance in what we have now rather than get one and sit down playing the waiting game.1) It's not like NVidia's DX12 performance is "awful", you'll still get to play future games with relatively good performance.
2) The games you play now won't be obsolete for years.
3) I agree with what others have said; AOS is just one game. We DON'T know if NVidia cards won't get any performance gains from DX12 under other games/engines.

You do not buy a new gfx card to play games TODAY, but for playing TOMORROW, next month, quarter and then for a few years (few being ~two), until the performance in new games regresses to the point when you bite the bullet and buy a new one.Most people do not have unlimited budget to upgrade every six months when a new card claims performance crown.

It's unlikely that the gaming market will be flooded by DX12 games within six months. It's unlikely to happen within a few years, even. Look at how slow DX10 adoption was.anubis44 - Thursday, February 25, 2016 - link
I think you're quite wrong about this. Windows 10 adoption is spreading like wildfire in comparison to Windows XP --> Vista. DX10 wasn't available as a free upgrade to Vista the way DX12 is in Windows 10.Despoiler - Thursday, February 25, 2016 - link
Just about every title announced for 2016 is DX12 and some are DX12 only. There are many already released games that have DX12 upgrades in the works.Space Jam - Wednesday, February 24, 2016 - link
Nvidia leading is always irrelevant. Get with the program :pNvidia's GPUs lead for two years? Doesn't matter, AMD based on future performance.
DX11 the only real titles in play? Doesn't matter, the miniscule DX12/Vulkan sample size says buy AMD!
