AMD Catalyst 14.6 Does Slightly Better With APITest OpenGL Tests

Last month I published some benchmarks where NVIDIA slaughtered AMD's Catalyst driver in APITest benchmarks, a set of OpenGL 4.x test cases. While these are just micro-benchmarks of modern OpenGL and designed for showing off potential solutions for problems to leading to lower driver overhead, there's been some improvements within the Catalyst 14.6 Beta on Linux. Up today are some new benchmarks of APITest using the latest AMD and NVIDIA drivers.

Even With Re-Clocking, Nouveau Remains Behind NVIDIA's Proprietary Linux Driver

Starting out the last week of July's Linux benchmarking on Phoronix is a fresh comparison of several NVIDIA GeForce graphics cards when comparing the performance of the latest open-source Nouveau driver against the latest NVIDIA proprietary Linux graphics driver. While the Kepler cards now support GPU re-clocking, the results aren't quite ideal yet.

AMD Radeon VDPAU Video Performance With Gallium3D

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.

NVIDIA VDPAU Performance Metrics On Ubuntu 14.04 Linux

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.

Open-Source Radeon Performance Boosted By Linux 3.16

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.

Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming

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.

Nouveau Re-Clocking Is Way Faster, Shows Much Progress For Open-Source NVIDIA

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.
