RYZEN fully supports ALL DX12 features. Including a few that Intel and NVidia. DX12's Explicit Multi-adaptor allows scalable performance increases far better than Crossfire allows.
RYZEN would perform far better with 2x RX 480 than using 1 GTX 1080. Especially the Ashes benchmark. Of course that would also show Intel in a bad light too.
Tom's Hardware used to run the Chessbase FritzMark test. I find the absence of that test troublesome.
So allow me to provide it for you. ChessBase reported on the results and RYZEN THOROUGHLY CRUSHES ALL INTEL 8 CORE 16 THREAD CPU.

Where is the Super Pi results? They too would should Intel in a good light unless of course RYZEN crushed i7 again.
