April 20, 2012 -- In what will certainly be controversial and disappointing to some Radeon Linux desktop users, AMD will soon announce that they will effectively be discontinuing support for several Radeon product families from their proprietary Catalyst driver. After that point, for future Linux distribution updates, the open-source Radeon Linux driver will be your only option for accelerated graphics. This is likely happening with the Windows Catalyst driver too, but at least there they have a better-maintained legacy driver process.
April 16, 2012 -- It's been a few months since last running any AMD Fusion tests under Linux, so here's a look at the AMD A8-3870K "Llano" APU performance under both the latest Catalyst driver and the open-source Radeon Gallium3D stack with Ubuntu 12.04. Besides the open-source driver being handily beaten by the Catalyst binary driver, the power efficiency is also a disappointment.
April 14, 2012 -- There is another new open-source Linux graphics driver entering development and it has already showed signs of success with basic 2D acceleration working. This new open-source driver is for Qualcomm's Snapdragon / Adreno and who is leading the development of this driver is also quite interesting.
April 13, 2012 -- Nouveau, the reverse-engineered open-source graphics driver for NVIDIA's entire range of graphics processors, is reaching a stable state where it's exiting the "staging" area of the Linux 3.4 kernel and being considered part of the standard, stable kernel configuration. How though is the Nouveau driver working out compared to NVIDIA's official, closed-source Linux graphics driver? Here are some new benchmarks from ten different graphics cards and other information on the state of Nouveau.
March 23, 2012 -- Following recent advancements in the open-source Radeon Linux driver like 2D color tiling support, I've carried out some new benchmarks of the open-source Radeon Gallium3D driver compared to AMD's official Catalyst driver. This time around, the open-source driver is seeing tests against AMD's binary blob when various performance-optimizing tweaks are enabled to see where the performance stands today.
March 21, 2012 -- In continuation of the Using The New Radeon Gallium3D 2D Color Tiling article from January, here's updated benchmarks of the latest Radeon Linux driver code with this performance-boosting feature enabled.
March 19, 2012 -- Recently I showed off some Intel DRM benchmarks from the Linux 3.3 kernel along with what will be in the Linux 3.4 kernel via drm-next. These results indicated some performance improvements on the side of Intel Sandy Bridge hardware, but how do the new kernel and Linux 3.4 impact the discrete Radeon graphics? Here's some benchmarks covering that side of the graphics table.
March 14, 2012 -- With the release of the Linux 3.3 kernel being imminent and the Linux 3.4 kernel drm-next already offering lots of changes, here are some Intel Sandy Bridge benchmarks comparing the Linux 3.2 kernel to a near-final Linux 3.3 kernel and then the drm-next kernel that's largely a 3.3 kernel but with the DRM driver code that will work its way into Linux 3.4.
March 09, 2012 -- After first being introduced on Windows years ago, and then FreeBSD and ReactOS support added last year, this week finally marked the release of TitaniumGL for Linux. TitaniumGL is self-described as a "freeware driver architecture" and carries a goal to support OpenGL on graphics cards with broken, bad, or missing OpenGL hardware drivers. Here are some benchmarks of TitaniumGL compared to NVIDIA's binary GPU driver and the Mesa/Gallium3D LLVMpipe software rasterizer.
February 24, 2012 -- 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.
