Testing of the latest Linux 3.6 kernel that's presently under development has revealed some additional OpenGL performance improvements with Intel graphics, at least concerning the latest-generation "Ivy Bridge" processors.

Recently I showed benchmarks of the Radeon Gallium3D driver for a mature Radeon HD 4870 graphics card over the past two years to look at the performance improvements made to this open-source Linux graphics driver. Up today are benchmarks of an old Radeon X1950PRO (R500 class) ATI graphics card when using the original "R300g" Gallium3D driver and testing every major Mesa release going back to Mesa 7.8 with the classic R300 driver.

With the upcoming release of Mesa 8.1, here's a look at how the AMD Radeon "R600" Gallium3D driver performance has changed over the past two years. This article has benchmarks of each major Mesa release going back to Mesa 7.9 of 2010 back when the R600 classic DRI driver was still in early development but the only viable choice for using accelerated open-source graphics on AMD Radeon HD 2000 series graphics cards and newer. For the most part, the open-source Radeon Linux graphics performance has advanced greatly in terms of OpenGL performance over the past two years, but it's not without some outstanding regressions.

Having now delivered Mesa 8.1 benchmarks looking at the hardware drivers for AMD R600g, Nouveau, R300g, Intel Ivy Bridge, and Intel Sandy Bridge, here are some benchmarks when on LLVMpipe.

A few days back I published benchmarks showing Intel's Ivy Bridge hardware regressing with Mesa 8.1. While those problems are still outstanding, the good news is that Intel's previous-generation Sandy Bridge hardware appears unaffected. Overall, Sandy Bridge is performing well with the soon-to-be-released Mesa 8.1 library for open-source Linux graphics drivers.

In recent days there have been updated Mesa 8.1 development benchmarks put out looking at the R600 Gallium3D, R300 Gallium3D, and Nouveau Gallium3D open-source drivers. Those results for the different drivers show that Mesa 8.1 is generally faster than the current Mesa 8.0 stable series, but that does not appear to be the case for Intel at the moment. It looks like there are some active regressions that are lowering the Intel Ivy Bridge graphics performance with their Mesa 8.1-devel driver.

Due to the extreme pace at which Chris Wilson has been releasing SNA architecture updates for Intel's open-source X.Org driver, here are another set of benchmarks of Intel Sandy Bridge HD 3000 graphics when comparing UXA and SNA using yesterday's Git code following the xf86-video-intel 2.20.2 driver release.

After delivering Mesa 8.0 vs. 8.1-devel benchmarks for the R600 Gallium3D driver that supports ATI/AMD Radeon hardware from the HD 2000 through HD 6000 series (along with similar Nouveau Gallium3D benchmarks), here is a look at the upcoming Mesa release when using the R300 Gallium3D driver with ATI Radeon X1000 series graphics cards.

Here are some recent benchmarks comparing Intel's SNA and UXA 2D acceleration architectures offered by their open-source Intel Linux graphics driver.

After last week sharing results for AMD Radeon R600g Gallium3D on Mesa 8.0 and 8.1-devel, here are benchmarks for several NVIDIA GeForce graphics cards comparing the OpenGL Gallium3D performance with Nouveau on Mesa 8.0 stable and Mesa 8.1-devel.
