16-Way NVIDIA GeForce vs. AMD Radeon Comparison - August 2017
Civilization VI on Linux remains in fairly rough shape. For the benchmark mode there is a major bottleneck and basically puts all the newer graphics cards on both drivers in the same light.
Xonotic is an open-source cross-platform game that continues to perform very well with the Radeon driver and hardware. The R9 Fury at 4K can run ahead of the GTX 1080 while the RX 580 are solidly ahead of the GTX 1060 and GTX 980.
With GpuTest's triangle test that is largely limited by vRAM performance, the R9 Fury is in line with the GTX 1080 Ti. It will be interesting to see where the RX Vega clocks in with its HBM2 memory.
