With Ubuntu 14.04 LTS there is improved support for multi-GPU laptops (commonly what's branded as NVIDIA Optimus configurations) where there is a discrete NVIDIA GPU used for high performance workloads to complement the low-power Intel integrated graphics. Ubuntu 14.04 LTS features better support for these Optimus / DRI PRIME configurations on both the open and closed-source graphics drivers. Here's the Ubuntu 14.04 multi-GPU experience along with some OpenGL benchmarks and power consumption numbers between the different configurations.

Tested yesterday at Phoronix was the AMD Catalyst 14.4 Linux performance where several newer, high-end graphics cards were tested from a Core i7 Haswell system. With that hardware, there was little in the way of OpenGL performance changes except for a couple of tests. Several Phoronix readers expressed interest in Catalyst 14.4 AMD AM1 APU tests in seeing if there are any improvements for the new APUs with Radeon R3 Graphics or performance improvements in general out of Catalyst 14.4 for reduced OpenGL overhead on lower-end processors. In this article are Catalyst 14.3 vs. 14.4 Ubuntu Linux benchmarks with an AMD Athlon 5350.

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.
