48% reference vs reference
33% AIB vs AIB

and this is a game that received a driver before Pascal launch....

lol how do you preach about maxwell vs pascal in dx12 and not know the results from literally the only game out that exists and uses async
even in the review that started this thread,by oc club, 1070 is 11% faster than TX in Hitman, 1080 is 41% over 980Ti. So it's 15-20% more than the usual dx11 difference.

I admit this is a very interesting result for a game that touts high usage of async compute. Thanks for the graph.

frankly Hitman dx12 results I gathered from different reviews made me buy my 1080, if that was still within 20-25% of 980Ti like in dx11 I wouldn't have done it.

That's a bone stock 980 Ti right?

Just +30% to the frames and you're only about 3 frames behind a stock 1080 even under DX12.

IDK what happened to the dx11 chart I posted. my point was 1080 gains in dx12 async, 980ti does not.




on second thought 1070 shows no gain in dx12 too. strange. must be a case for pure cpu bottleneck then.

anyway, in just about every review hitman dx12 shows 1080 widen the gap over gm200 cards.

the real test for Pascal will be the upcoming dx12 titles for sure.

DirectX 12 is not only async,the 1070 is a cutdown 1080,why it does not gain anything?

I think what we are seeing over there is DX12 with it's lower cpu overhead rather async compute.

In fact,look at the 4K benchmarks,DX11 vs DX12 on 1080 is 1 FPS difference.

Not to mention that as far im aware,all Pascal has of new regarding async is pre-emption,wich should just make the card not lose performance when facing async like Maxwell.

Honestly we need toggles like the one in Doom to be able to claim things about async,as of now most games lump async and DX12 toghether and those are two different things.

In that DX11 chart even the Zotac 1080 is just 12% faster than a stock 980 Ti, and there's less than 1 FPS difference between the 1070 and 1080, does that seem normal to you? I'd say it looks like a pretty clear case of CPU bottlenecking to me.

That CPU bottleneck is gone under DX12, and the 1080 is simply performing as it should be instead of being artificially constrained.

Yeah "problem" here is; They used a reference 980 Ti, like in most 1070 and 1080 reviews. A custom 980 Ti is ~20% faster than reference, out of the box. A custom 1080/1070 is only slightly faster than FE.
Add 20% performance to those 980 Ti numbers, it would be ahead of 1070 and not far behind 1080 FE.

If you add the 20% to Hitman 1440p DX12 results, the 980 Ti would be at 47/51 fps instead of 39/42.6 fps, pretty much the same or even slightly more than a custom 1070.

Custom 980 Ti vs Custom 1080 would be within the 20-25% you are talking about.. I'm not impressed tbh.

custom 980ti vs custom 1080, 33% difference, and that's a pretty fast 980ti with 1405/7200, my 6G Gaming ran 1354/7010 with 81.4 asic

That really is not very fast for a 980 Ti. It's out of the box boost clocks for custom cards, and look how close it is to 1080 FE. The custom 980 Ti is pretty much on par with custom 1070.

The custom 980 Ti has ~23% better performance than the reference card marked in red.
The best custom 1080 is only ~8% better than FE.

GM204 scales better with OC, if you added ~100 MHz on both chips, the 980 Ti would be even closer to 1080 FE performance.

Yes, 1080 is faster. But 980 Ti is one year old. Launch price was the same. Worst shrink I've seen I think, it did not offer end users much better performance for the money. I guess it will get better when AMD launches Vega.

I'll probably grab a Vega 10 or 11 when they hit.
