VEGA-64 at a cheaper price, lower power consumption (coming in 2018), better drivers, and more GAMES that properly utilize it would make a really great product.
*However, NVidia will be coming out with a Volta product that adds in better ASync Compute etc so competition is going to heat up between quite similar GPU architectures in 2018.
(Gamers Nexus did a review of the Titan V100 that has a Volta GPU in it. It also has tensor cores that don't get utilized for gaming but in his quick gaming tests it appears it has good ASync Compute as it managed to get up to 2x the FPS as a GTX1080 at a lower frequency... I won't bore you with the details but normally things don't scale CUDA vs FPS etc so it's a good SUGGESTION at the very least that gaming Volta for DX12/Vulkan especially is on track... probably other features in there too, and frankly I think AMD and NVidia GPU's are going to get incredibly CLOSE in architecture especially considering that the PS4, XBOX ONE and likely PS5 etc will be based on a GCN architecture so I think we'll just fine-tune that)
