On Monday AMD made publicly available the release candidate to the Catalyst 14.4 Linux driver that brings full OpenGL 4.4 support. Some Phoronix readers have reported performance changes with this new driver update, so I have done some comparison tests on several AMD Radeon graphics drivers to see how the performance compares with Catalyst 14.4 on Ubuntu Linux.

For those curious how AMD's AM1 APUs are running with OpenCL workloads given the company's focus on HSA, here's a wide-range of OpenCL benchmarks from the four Athlon and Sempron AM1 APUs currently on the market while running Ubuntu 14.04 LTS.

For the past week now we have been extensively benchmarking AMD's new AM1 APUs with all the current models available to the public: the Sempron 2650 / 3850 and Athlon 5150 / 5350. All of our testing up to this point has been using an updated Linux kernel and Mesa for the open-source Linux graphics driver experience with these APU Radeon R3 Graphics. Today, we're looking at the performance of the open-source RadeonSI Gallium3D driver in multiple configurations compared to the proprietary Catalyst Linux driver.

Yesterday I delivered the first Linux benchmarks of the AMD Athlon 5350 with Radeon R3 Graphics. Benchmarks of the socketed Kabini APU are ongoing at Phoronix in a variety of different software and hardware configurations. The tests that have just wrapped up today are checking out the performance when upgrading the Linux kernel and Mesa compared to what's shipped by default in Ubuntu 14.04 LTS.

Last week we covered a 13-way Radeon GPU comparison on Ubuntu 14.04 and we also looked at the state of Nouveau on Ubuntu 14.04 with many NVIDIA GeForce graphics cards. In concluding our latest round of open-source graphics driver tests from the upcoming Ubuntu 14.04 LTS "Trusty Tahr", here's a 20-way graphics processor comparison using AMD Radeon, NVIDIA GeForce, and Intel HD Graphics hardware.

In my testing of Ubuntu 14.04 LTS with the Linux 3.13 kernel and Mesa 10.1 for the open-source graphics driver stack provided by Nouveau for NVIDIA GeForce graphics hardware, only the Fermi and Kepler GPUs are running reliably. While these newer NVIDIA GPUs are running stable with Ubuntu 14.04, the performance is still a wreck due to lack of reclocking.

To complement last week's Radeon Windows Catalyst vs. Linux Gallium3D vs. Linux Catalyst OpenGL performance comparison on Ubuntu 14.04 LTS, here's benchmarks of thirteen different AMD Radeon graphics cards on the near-final state of Ubuntu 14.04 LTS "Trusty Tahr" in its current development form.
