AMD's RadeonSI Gallium3D Is Improving, But Catalyst Is Much Better

Written by Michael Larabel in Display Drivers on 31 October 2013 at 03:08 PM EDT. Page 5 of 5. 21 Comments.

For the GpuTest OpenGL workloads, the RadeonSI open-source performance was a small fraction of the speed of the closed-source Catalyst driver.

When testing the R600 Gallium3D driver earlier this week compared to the Catalyst driver for Radeon HD 5000/6000 series graphics cards, the results showed the open-source driver competing with Catalyst. For the Radeon HD 7000 series hardware and newer, this is far from the case. The benchmarks today showed that overall the AMD Radeon R9 270X graphics card was running at a fraction of the speed of the closed-source Catalyst driver on Ubuntu Linux. While testing today was just from one graphics card, in early November will be more test results but they show basically the same findings as today with the R9 270X.
