When jumping up to ultra image quality settings, the open driver stack was at 70% the speed of the binary blob.

Lastly with ultimate image quality settings for XOnotic, the driver difference was at 73%.

Plot3D shows the binary driver still being significantly faster.

The AMD Kaveri Linux test results today don't show much of a performance change when using the latest driver components provided by Mesa 11.2 and Linux 4.5. Unlike our other tests with discrete GPUs, DRI3 didn't appear to have much of an impact on the A10-7850K OpenGL graphics performance. From the tests ran for this article, the A10-7850K Kaveri on the open-source driver was generally running 70~80% the speed of the proprietary AMD Linux driver.

Stay tuned for more tests still being carried out at Phoronix.
