Up for publishing today is a multi-card multi-driver comparison spanning several generations of discrete ATI/AMD Radeon graphics cards looking at the Radeon OpenGL performance as found by default in Ubuntu 12.04, as found when updating to the latest "Git" development code, when tweaking the latest development code for maximum performance, and finally when using the proprietary AMD Catalyst Linux display driver.

As the Intel Ivy Bridge benchmarks being delivered on Phoronix and coming up in the coming days are frequently using the latest Intel Linux graphics development stack, for those curious here is a comparison between the stock Ubuntu 12.04 packages and when running the latest Linux kernel / Mesa / libdrm / xf86-video-intel Git DDX.

Going back to last year there's been the "Glamor Acceleration" project out of Intel to accelerate the 2D operations within X using OpenGL on Mesa. This is similar to the Xorg state tracker approach and while it's not yet enabled by default, Intel OTC developers have been making much progress in recent months. In this article is a look at the recent Glamor update while comparing it to the stock Intel UXA acceleration as well as to the other experimental acceleration option: Intel SNA.

Last week the R600 LLVM compiler was hooked up for AMD's open-source Gallium3D driver. This LLVM shader compiler is important particularly for OpenCL enablement within the open-source Radeon Linux graphics driver, but still there is some ways to go before that code is ready for production use.

Thanks to clean-room reverse-engineering, it is already possible to run the NVIDIA GeForce GTX 680 "Kepler" graphics card on a fully open-source graphics driver complete with OpenGL acceleration. Here are the first benchmarks of this work-in-progress, community-created open-source GeForce 600 series graphics driver.

Committed to the Mesa and libdrm Git repositories last week for Nouveau, the open-source NVIDIA Linux driver, was the "major libdrm rewrite" designed to step-up this reverse-engineered driver. What impact did these invasive changes have on the Nouveau driver's performance? Here are benchmarks comparing before-and-after as well as how the Nouveau driver compares to the proprietary NVIDIA Linux graphics driver.

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.

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.

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.

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.
