Nouveau Driver Remains Much Slower Than NVIDIA's Official Driver

While benchmarks this week have shown the Nouveau driver can be faster with the Linux 3.8 kernel, further benchmarks have shown that this reverse-engineered open-source driver for supporting the spectrum of NVIDIA GPUs is still at a significant loss compared to NVIDIA's official but proprietary Linux graphics driver.

Nouveau NVIDIA Driver Can Be Faster With Linux 3.8

Published already on Phoronix have been benchmarks of the in-development Linux 3.8 kernel when it comes to measuring the DRM graphics driver performance improvements for AMD Radeon hardware. In this article is a look at the Nouveau driver performance, the reverse-engineered open-source NVIDIA graphics driver. There's a fair amount of changes to look forward to in the next Linux kernel release for Nouveau and it's yielding some performance improvements.

Checking In On Nouveau Gallium3D For Mesa 9.1

Up this holiday weekend on Phoronix are benchmarks of the open-source Nouveau Gallium3D when comparing the driver's state on the Git branches of Mesa 9.0 and Mesa 9.1-devel. While checking in on the latest Mesa Nouveau code, three NVIDIA GeForce graphics cards were benchmarked from a development snapshot of Ubuntu 13.04.

AMD 2012 Catalyst Driver Year-In-Review

For the past seven years I have been writing annual year-in-review articles for the AMD and NVIDIA Linux graphics drivers. Much progress has been made in recent years for bettering the OpenGL Linux support from these leading closed-source graphics drivers and this year is no exception. Up today is a recap of this year's AMD Catalyst graphics driver releases plus benchmarks of this year's driver releases going back to Catalyst 11.12.

AMD Radeon Performance Preview On Linux 3.8

With word this week that there's some performance improvements for the open-source Radeon Linux graphics driver to be found with the Linux 3.8 kernel as a result of the a-synchronous DMA engine support, some very early benchmarks of the "drm-next" code were done from five different AMD Radeon graphics cards. In extreme cases, the open-source graphics driver can deliver 10x higher OpenGL frame-rates with the experimental kernel.

Radeon HyperZ R300g Performance

With Marek Olšák having fixed-up the R300 Gallium3D HyperZ support and then finally enabling this performance-boosting technology by default for the vintage Radeon X1000 (R500) series graphics cards, new benchmarks were conducted to look at the performance impact of ATI HyperZ finally being flipped on in this legacy ATI Linux graphics driver.
