18-Way GPU Linux Benchmarks, Including The Radeon RX 460 & RX 470 On Open-Source
The R9 290 was back into its regressed state with Tesseract and the RX 460 continued performing around the same speed as the R7 260X.
Hopefully with AMD's Vega the performance-per-Watt will be more competitive with modern AMD GPUs.
BioShock Infinite performs very poorly on the open-source Radeon driver stack. However, with the very latest Mesa Git code in the past few hours, the performance should now be much better. Stay tuned for some follow-up tests.
