Running Mesa 9.2-devel + LLVM 3.3 SVN With The R600 Back-End: The last time I extensively tested the AMD Radeon Gallium3D LLVM shader compiler back-end was last April. Since then the R600 LLVM back-end has matured quite a lot with new features and was merged into upstream LLVM. In the past few days I carried out some new tests on several different graphics cards using Mesa Git master of the R600 Gallium3D open-source graphics driver.
Mesa 9.0 vs. Mesa 9.1-devel On Intel Sandy Bridge: For those Intel "Sandy Bridge" CPU owners with integrated HD 2000/3000 graphics, here are some benchmarks showing the performance of the current Mesa 9.1-devel Git code compared to the stable Mesa 9.0 release. There are a few performance improvements to be found for this open-source Intel Linux graphics driver.
Mesa 9.1-devel LLVMpipe With LLVM 3.1/3.2: With a number of commits made to the mainline Mesa repository recently that concern the LLVMpipe Gallium3D driver for pushing OpenGL onto the CPU, here are benchmarks of the very latest Mesa Gallium3D development code from and AMD FX-8350 Vishera Eight-Core CPU when using both LLVM 3.1 and LLVM 3.2 SVN.
AMD Catalyst vs. Linux 3.7 + Mesa 9.1-devel Gallium3D Performance: In this article is a large OpenGL performance comparison looking at the frame-rates in different Linux games for different AMD Radeon Linux graphics cards when running the stock Ubuntu 12.10 operating system (Mesa 9.0 + Linux 3.5), the Catalyst Linux driver (fglrx 9.0.2) as found in the Ubuntu Quantal archive, and then when running the very latest Radeon Git code: The Linux 3.7 kernel, Mesa 9.1-devel, and xf86-video-ati 7.0.99 Git.
Mesa 8.1-devel On Radeon Gallium3D: Earlier this week I shared a pleasant surprise in Mesa 8.1 Radeon Gallium3D with some significant performance improvements to be found in the current Mesa Git code-base for the "R600g" driver in some OpenGL games. In this article is a more diverse look at the current state of Mesa 8.1 development for R600 Gallium3D and comparative benchmarks from every major release going back to Mesa 7.10.
