More specifically, NV haven't mentioned the full architecture of Pascal as it is NDA. Like Arctic Islands. The assumption is that knowing the move to DX12 would have brought a more basic API and having seen AMD utilise Mantle to reasonable effect, NV aren't exactly going to have sat on their laurels. With Maxwell, the drive was clearly to knock down CUDA's compute (which is great at parallelism) to focus on power efficiency with faster clocks. That gave the 980ti enormous headway for DX11 which is still the current and ruling API. Nvidia'a DX11 Maxwell focus, compared to GCN's DX12 advantage wasn't a fantastic move by AMD. Latest figures show despite Fiji parts being readily available, they are not selling as well as Maxwell parts.
I have no idea how Pascal will fare against Polaris. Perhaps Polaris (or whatever the arch is called) will have enough tweaks to finally and resoundingly become the gold standard in gfx architecture. Maybe Pascal will be a Maxwell Volta bastard son and simply hold on till Volta arrives proper?
What is for sure is that this single, DX12 bench isn't any revelation. If Async isn't a dev's priority (for whatever reason) then GCN loses it's edge. If Nvidia buy into some AAA titles before Pascal is out (with assumed parallelism) they'll be sure to 'persuade' lower focus on Async.
Roll on Summer - another round of gfx wars
It already started with Rise of the Tomb Raider
The last PC UE4 build still didn't have Async either but the console version does.
