AMD Radeon RX 590 Linux Benchmarks, 18-Way NVIDIA/AMD Gaming Comparison
The Radeon RX 590 really couldn't handle Rise of the Tomb Raider well at 4K even with the lowest quality settings, but was interesting to see in this game its performance meeting the Radeon R9 Fury.
The open-source OpenGL Tesseract game is one of the scenarios where the RadeonSI driver stack performs really well still compared to the NVIDIA Linux driver. With Tesseract, the RX 590 performance was just behind the GeForce GTX 1070.
