The OpenGL Speed & Perf-Per-Watt From The Radeon HD 2000/3000 Series Through The R9 Fury
At least here, the Radeon R9 Fury doesn't run into any odd re-clocking / performance issues. The R9 Fury is 47x faster than the Radeon HD 3650 for this very demanding synthetic OpenGL benchmark. The performance-per-Watt, however, for this test when going from the HD 3650 to R9 Fury was 10x.
Under OpenArena, the R9 Fury on this latest Linux driver was still problematic. However, the results from the other GCN graphics cards are certainly interesting for the evolution of Radeon graphics.
And then the more demanding, newer OpenArena release that still runs on old HD 3000 series hardware:
