As the second part of our Linux graphics testing this week after a Radeon R600/RadeonSI performance update with the Linux 3.16 kernel and Mesa 10.3-devel are some comparative numbers that include Intel's Haswell HD Graphics and various NVIDIA GeForce graphics cards on the Nouveau driver.

After earlier this week posting some fresh NVIDIA VDPAU video playback performance tests, here is some testing of the open-source AMD Radeon driver with R600 and RadeonSI Gallium3D drivers while using the VDPAU state tracker for open-source, accelerated video playback using the graphics cards' UVD engine.

It's been a while since last running any video acceleration benchmarks at Phoronix so this week we're running a fresh set of VDPAU (Video Decode and Presentation API for Unix) benchmarks with NVIDIA's official driver plus for AMD Radeon hardware using the Radeon VDPAU state tracker support.

Besides the Nouveau driver performance being faster thanks to experimental re-clocking when using the Linux 3.16 kernel, there are also performance improvements to note with some generations of AMD graphics processors.

Back in 2012 with the NVIDIA 310 Linux driver series a threaded OpenGL optimization was added to the proprietary graphics driver. When this driver premiered we tested NVIDIA's Linux threaded OpenGL optimizations to mixed results. We're back now re-testing the OpenGL threaded optimizations to see if it makes any more of a difference now with modern Linux games and OpenGL workloads while using the latest 337.25 Linux driver.

Earlier this week on Phoronix we covered the steps to trying out Nouveau re-clocking with Linux 3.16, assuming you're running a supported NVIDIA GPU that can currently be statically re-clocked using this reverse-engineered graphics driver. While the support is still experimental and isn't intended for end-users, here are some fresh benchmarks of the Nouveau driver DRM code for Linux 3.16 when re-clocked.

Last weekend I published 2D performance benchmarks comparing Nouveau to NVIDIA's official driver. To no real surprise, the proprietary NVIDIA driver beat Nouveau in most micro-benchmarks when it comes to 2D (and separately, 3D) performance. With the open-source Radeon stack, however, it presents a much tougher fight against the proprietary Catalyst driver.

With the Linux 3.16 kernel comes the ability to re-clock select NVIDIA GeForce GPUs when using the open-source, reverse-engineered Nouveau driver. Here's my first impressions with trying out this option to maximize the performance of NVIDIA graphics cards on open-source drivers.

With the APITest OpenGL 4.x tests developed by John McDonald at NVIDIA who is now working for Valve on their Linux-related endeavors, the AMD Catalyst driver gets absolutely annihilated for these GL4 micro-benchmarks.
