Radeon RX 550 Linux Benchmarks: $89 Polaris GPU On Open-Source
The NVIDIA line-up remains much faster with OpenArena on the NVIDIA driver than DRM-Next + Mesa 17.2-dev on Radeon GPUs.
The Tesseract performance is certainly high for this open-source game but the GTX 1050 is a much stronger alternative for those not concerned by their graphics driver's license.
With Unigine Superposition, the RX 550 was the slowest card tested.
