Radeon Linux 4.6 + Mesa 11.3 vs. NVIDIA Linux Performance & Perf-Per-Watt

The Tesseract numbers are still a disappointment for this current open-source AMD stack on this system compared to the NVIDIA proprietary driver.

There's finally a red win, when testing the synthetic Furmark OpenGL performance test.

At least the open-source AMD driver stack and the tested hardware doesn't perform too bad in the synthetic OpenGL GpuTest cases, but it's a pity that Radeon/AMDGPU + RadeonSI doesn't universally run that well for Linux games.

For reference, here is the system power draw and GPU core temperature over the course of all the 1080p Linux OpenGL tests ran for this article:
