New AMD GPU Performance To Be Boosted By Linux 4.5; How It Compares To The Binary Blob

Last week I posted some AMD proprietary vs. open-source AMD Linux driver benchmarks using the very latest code. Left out of that earlier comparison was the R9 Fury series with Fiji GPU as well as newer graphics cards using the Tonga GPU. These graphics cards are supported by the AMDGPU DRM driver rather than the long-standing Radeon DRM driver. As I've been mentioning a lot this week, Linux 4.5 will bring the PowerPlay power management / re-clocking support to AMDGPU. In this article are showing benchmarks of the Fiji and Tonga GPUs under Linux 4.4 and Linux 4.5 DRM-Next along with the Catalyst 15.9 driver as shipped by Ubuntu 15.10.

With R600g Now Supporting OpenGL 4.1, See How The Open-Source Performance Compares To AMD Catalyst

There are two reasons for doing some end-of-the-year Radeon R600 Gallium3D driver testing with pre-GCN graphics cards. First, since the pre-GCN (HD 6000 series and older) support is being dropped by the new Radeon Software driver. Secondly, the R600g open-source driver finally supports OpenGL 4.1 for select GPUs. In this article is a look at the AMD Catalyst Linux driver with the last official release for HD 6000 series hardware compared to the very latest open-source Radeon graphics stack on Ubuntu Linux with a variety of interesting OpenGL Linux game tests.

Radeon DRM Linux 4.4 + Mesa 11.1 + DRI3 vs. AMD's Proprietary Driver

On Friday I posted benchmarks showing Nouveau's re-clocked performance relative to NVIDIA's proprietary driver for showing the performance potential of NVIDIA's GeForce GTX 600/700 series with the performance state code there beginning to work. That article was followed by AMDGPU driver tests on Linux 4.4 against Catalyst for the newest AMD GPU tech that uses this newer Direct Rendering Manager driver. The third test now is comparing the Radeon DRM performance on Linux 4.4 against AMD's binary blob when using older AMD GCN GPUs as well as a Northern Islands GPU for reference.
