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 ESTClosing Thoughts
Wrapping up our second look at Ashes of the Singularity and third overall look at Oxide’s Nitrous engines, it’s interesting to see where things have changed and where they have stayed the same.
Thanks to the general performance optimizations made since our initial look at Ashes, the situation for multi-GPU via DirectX 12 explicit multi-adapter is both very different and very similar. On an absolute basis it’s now a lot harder to max out a multi-GPU configuration; with reasonable quality settings we’re CPU limited even up to 4K, requiring we further increase the rendering quality. This more than anything else handily illustrates just how much performance has improved since the last beta. On the other hand it’s still the most unusual pairing – a Radeon R9 Fury X with a GeForce GTX 980 Ti – that delivers the best multi-GPU performance, which just goes to show what RTG and NVIDIA can accomplish working together.
As for the single GPU configurations, I’m not sure things as they currently stand could be any more different. NVIDIA cards have very good baseline DX11 performance in Ashes of the Singularity, but they mostly gain nothing from Ashes’ DX12 rendering path. RTG cards on the other hand have poorer DX11 performance, but they gain a significant amount of performance from the DX12 rendering path. In fact they gain so much performance that against traditional competitive lineups (e.g. Fury X vs. 980 Ti), the RTG cards are well in the lead, which isn’t usually the case elsewhere.
Going hand-in-hand with DX12, RTG’s cards are the only products to consistently benefit from Ashes’ improved asynchronous shading implementation. Whereas our NVIDIA cards see a very slight regression (with NVIDIA telling us that async shading is not currently enabled in their drivers), the Radeons improve in performance, especially the top-tier Fury X. This by itself isn’t wholly surprising given some of our theories about Fury X’s strengths and weaknesses, but for Ashes of the Singularity performance it further compounds on the other DX12 performance gains for RTG.
Ultimately Ashes gives us a very interesting look at the state of DirectX 12 performance for both RTG and NVIDIA cards, though no more and no less. As we stated at the start of this article this is beta software and performance is subject to change – not to mention the overall sample size of one game – but it is a start. For RTG this certainly lends support to their promotion of and expectations for DirectX 12, and it should be interesting to see how things shape up in March and beyond once the gold version of Ashes is released, and past that even more DirectX 12 games.

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!
