And yet even in this benchmark, which would appear to be well-suited to AMD's hardware, the Fury X is still neck and neck with the 980 Ti. The real issue the benchmark highlights, to me anyway, is not that AMD's DX12 performance is so good, but that their DX11 performance (particularly in this example) is so bad. I don't see how you can look at this one benchmark and draw the conclusion that AMD has a better architecture for the future, when their premier card is still tied with Nvidia's (likewise for the 980 and 390X).

Edit: And if anyone is curious, here are the Gen 3/Gen 2 results for the 3DMark API test on a 290X: (Gen 2 / Gen 3)

DX11 ST: 1,298,473 / 1,265,204
DX11 MT: 1,324,209 / 1,311,353
Mantle: 18,476,350 / 18,917,266
DX12: 17,774,164 / 20,542,867

So Mantle and DX12 are faster, but somehow DX11 is slower in Gen 3.

Forceman's Law: Any AMD/Nvidia GPU thread, no matter what the topic, will eventually include a post referencing the GTX 970.
