NVIDIA GeForce GTX 1660 Linux Benchmarks
Deus Ex: Mankind Divided remains one of the most demanding Linux OpenGL games. The GeForce GTX 1660 here was running between the RX 580 and RX 590 atop the RadeonSI Gallium3D driver.
In this game, the GeForce GTX 1660 series delivers double the performance-per-Watt of the Radeon RX 580/590.
With the HITMAN OpenGL Linux game port the GeForce GTX 1660 had a tough time hitting the 60 FPS average at 1440p with medium quality settings while the Radeon RX 580 was performing much stronger -- in fact, the AMD GPUs with RadeonSI Gallium3D were performing well ahead of the NVIDIA competition.
