The year began with Intel launching their "Sandy Bridge" processors. While the CPU performance was very impressive for these latest-generation Intel processors, the graphics performance under Linux was a problem. The drivers were not ready in time. Well, they actually were technically available, but in Git source form and not easy for Linux desktop customers. There were also some initial hurdles in the Sandy Bridge Linux graphics support. However, over the past year, the Intel OSTC developers working on the open-source graphics support have dramatically improved the situation. As this article recaps the performance over the past year, Sandy Bridge is now rocking under Linux and Ivy Bridge is ready to go.

What happens if you build Mesa/Gallium3D with LLVM's Clang compiler or the LLVM DragonEgg plug-in with GCC? It has been asked before, so here is an answer.

It's been a while since last looking at the state of power management for Radeon GPUs, but here's an updated look at the various options surrounding power management for modern ATI/AMD graphics processors and their effectiveness. Various drivers, graphics cards, and tuning options are compared.

For those that are thinking about trying out the Sandy Bridge New Acceleration (SNA) architecture option for 2D graphics acceleration by the xf86-video-intel X.Org Linux driver, here are some benchmarks from the recent xf86-video-intel 2.17 release.

Earlier this month I showed the Intel graphics performance hasn't improved much in the Linux 3.2 kernel (but there might be a boost when RC6 is flipped on), but how is this new kernel shaping up for NVIDIA hardware owners wishing to use the open-source and reverse-engineered Nouveau driver? In this article are some benchmarks of the Nouveau DRM driver from recent Linux releases.

As reported earlier this week, HiZ support is now ready for Intel Sandy Bridge graphics under Linux with the Mesa driver. A set of more than three dozen patches were published that finalize this support for Sandy Bridge (Gen6) while the Ivy Bridge (Gen7) support is almost there but there are some performance regressions still being worked out by Intel's OSTC developers.

Back in September I provided the most comprehensive AMD Radeon Linux graphics comparison that took 28 graphics cards from all supported ATI/AMD Radeon product families and tested them under Linux using the latest Catalyst driver as well as the open-source Mesa/Gallium3D driver. In this article is a similar comparison on the NVIDIA side as I take most of the GeForce graphics cards at my disposal and try them under the NVIDIA binary Linux driver and the community-developed open-source "Nouveau" driver. Not only is the OpenGL performance looked at for multiple generations of NVIDIA hardware, but the thermal and power consumption is compared too. In certain OpenGL workloads, the open-source Linux driver is now faster than NVIDIA's own driver for select graphics cards in a fair comparison, but overall the NVIDIA blob still reigns supreme.

While KVM may be very fast for Linux virtualization, one of the areas where VMware and VirtualBox are superior is when it comes to the ability to provide hardware-accelerated 2D/3D support to guest virtual machines that ultimately is passed onto the host and its graphics card / driver. In this benchmark is a look at the gaming performance of Oracle's VM VirtualBox 4.1 when using their "Chromium" driver to enable guest Linux OpenGL acceleration.

A few days back when testing the Linux 3.1 kernel with Intel's Sandy Bridge hardware and then the Intel RC6 power-savings support, I also ran some updated benchmarks of SNA, the new Intel acceleration architecture available from their graphics driver.

In September the 2011 Linux Graphics Survey came to an end, but due to Oktoberfest, AMD Bulldozer Linux testing, OpenBenchmarking.org developments, and other matters, I didn't have time to look at the survey results until this weekend when getting ready for the Ubuntu Developer Summit. Here's the 2011 results looking at what Linux desktop end-users are running when it comes to graphics cards and drivers as well as their key concerns.
