16-Way NVIDIA GeForce vs. AMD Radeon Comparison - August 2017
Deus Ex: Mankind Divided with low quality settings is another stellar showing for the current Radeon Linux driver code with the RX 580 and R9 Fury being rather close in performance and both ahead of the GTX 980 Ti.
Though at ultra image quality settings the results recede a bit but overall the AMDGPU+RadeonSI Gallium3D stack running admirably compared to where it was at just a few years ago.
