The OpenGL Speed & Perf-Per-Watt From The Radeon HD 2000/3000 Series Through The R9 Fury
The Radeon HD 3850 was able to run Counter-Strike: Global Offensive, but only at a 6 FPS average... The Radeon HD 3650 was obviously too painful to even watch for testing. These results at 2560 x 1600 show how the performance has evolved of Radeon GPUs going back nearly ten years. Sadly though, the Radeon R9 Fury results on the open-source driver stack was a letdown. Even with using the latest RadeonSI Gallium3D Git code and using DRM-Next with PowerPlay enabled, the open-source driver is still running into evidently some re-clocking problems or other bottleneck with the Fiji GPU.
Eventually the R9 Fury open-source Linux driver support will improve, but ignoring that, it's incredible to see how the performance has evolved going up to the R9 290. The R9 290 was 17x faster than the HD 3850 for CS:GO.
For a look at the performance-per-Watt:
There's a 10x improvement in the performance-per-Watt when going from the Radeon HD 3850 to Radeon R9 290. From the Radeon HD 4870 (RV770) to Radeon R9 290 was a 4.7x improvement.
