Ah current games like? Warhammer, AoTs, Hitman, Farcry Primal, Battlefront . . .? Doom with Vulkan? Dues Ex? BF 1? Plenty of games that AMD does better and still some unknowns with upcoming big titles. Still Nvidia has GP 104 out unless AMD cuts some prices pretty low Nvidia will dominate on the high end.
Lets see I don't think they will have any discernible advantage in DX12 only games AMD has worked on will they get anything out of, its going to be the same old same old, nV wins some, AMD wins some, no overall advantage.
