AMD Radeon RX 5700 / RX 5700XT Linux Gaming Benchmarks
Tesseract is an open-source OpenGL game that traditionally has performed quite well on RadeonSI against NVIDIA under Linux and does remain that way with Navi.
For Counter-Strike: Global Offensive at 5K, the Radeon RX Vega 64 was matching the Vega 64 while the RX 5700XT did manage to match the GeForce RTX 2080.
Deus Ex: Mankind Divided's performance on Linux came up short and illustrated a RadeonSI shortcoming with the RX 5700 ending out below a Vega 56.
