Maxwell (NX) vs GCN (PS4/XBOne): Real World Teraflop Performance Comparison.

I don't know why you think that GPUs inside PS4 and XOne are GCN 1st gen. PS4's GPU (due to number of ACEs) looks like 290X/390X cut in half with 2CUs disabled and XOnes is like 7790/260X with 2 CUs disabled (or 360)...they are all 2nd gen GCN.

So you already have pretty good benchmark for 2nd Gen GCN vs Maxwell - 390X vs 980Ti:

DX12 are Ashes and Hitman.

Now, it is hardly even debatable that nVidia generally has more efficient architectures (looking at 1070@150W vs 480@150W is pretty much all that is needed), it's just that difference when it's DX12 or Vulkan (which is best we can hope for to see in terms of benchmarks) is not as big as DX11 tests where nVidia usually smokes AMD.

Still, theres quite a bit of time left for NX speculation, and for the sake of science is my responsability to give everyone the most accurate analysis I can (not saying that my analysis will be anything more than BS, but I can still try). I'll analyse this data and update the OP accordingly. Hopefully by tomorow.

PS - To everyone, I wouldn't mind having a few more benches especially from Vulkan.
