Michael Larabel over at Phoronix keeps plugging away at testing the performance of PC hardware under Linux, and he's presented the open-source community with quite a holiday present: a comparison of OpenGL gaming performance of 31 different AMD and Nvidia graphics cards. In almost all cases, the Nvidia cards deliver superior performance to their standard AMD adversaries,
For a scene with so much red, it didn't seem to run very well on AMD graphics hardware
We must note that testing was performed with open-source AMD and proprietary Nvidia drivers. Had the Nvidia cards been tested with the open-source Nouveau driver, the results likely would have been different. All told, Michael tested using twelve games plus Unigine Heaven and Phoronix's in-house Linux graphics performance benchmarking tool.
Games tested run the gamut from popular e-sports title Counter-Strike: Global Offensive and recent AAA-title Deus Ex: Mankind Divided to the more obscure Xonotic. The test rig was based around an Intel Xeon E3-1280v5 four-core CPU based on the Skylake architecture running at 4 GHz. This comparison was strictly OpenGL—no Vulkan testing was included. Despite the overall Nvidia sweep, the results are complicated and quite application-specific. If you want to play TuxRacer on your GeForce or Radeon, take the time and check out the results.
