31-Way NVIDIA GeForce / AMD Radeon Linux OpenGL Comparison - End-Of-Year 2016
With Metro Last Light Redux at 1080p, the R9 Fury only performs around the speed of a GTX 760 and short of a GTX 680... And that's with the open-source AMD stack already performing much better than AMDGPU-PRO with this game.
Though when pushing the cards harder by Metro Last Light Redux at 4K, the Radeon R9 Fury is at least running with the GeForce GTX 980.
Portal was tested mostly as a test of comparing well to the older NVIDIA/AMD GPUs in this comparison.
