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.

Intel Ivy Bridge Acceleration Of UXA vs. SNA

It's been a few months since last delivering any Intel SNA acceleration architecture benchmarks but with all of the many recent xf86-video-intel 2.20.x driver releases, here's some new benchmarks comparing the UXA and SNA acceleration back-ends for Intel's Ivy Bridge hardware.

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.

Mesa 9.0 vs. Mesa 9.1-devel On Intel Sandy Bridge

For those Intel "Sandy Bridge" CPU owners with integrated HD 2000/3000 graphics, here are some benchmarks showing the performance of the current Mesa 9.1-devel Git code compared to the stable Mesa 9.0 release. There are a few performance improvements to be found for this open-source Intel Linux graphics driver.

Mesa 9.1-devel LLVMpipe With LLVM 3.1/3.2

With a number of commits made to the mainline Mesa repository recently that concern the LLVMpipe Gallium3D driver for pushing OpenGL onto the CPU, here are benchmarks of the very latest Mesa Gallium3D development code from and AMD FX-8350 Vishera Eight-Core CPU when using both LLVM 3.1 and LLVM 3.2 SVN.

AMD Catalyst vs. Linux 3.7 + Mesa 9.1-devel Gallium3D Performance

In this article is a large OpenGL performance comparison looking at the frame-rates in different Linux games for different AMD Radeon Linux graphics cards when running the stock Ubuntu 12.10 operating system (Mesa 9.0 + Linux 3.5), the Catalyst Linux driver (fglrx 9.0.2) as found in the Ubuntu Quantal archive, and then when running the very latest Radeon Git code: The Linux 3.7 kernel, Mesa 9.1-devel, and xf86-video-ati 7.0.99 Git.

AMD's New Catalyst Linux Driver Isn't Too Good

Last week marked the release of a new AMD Catalyst Linux driver beta that was intended to improve the AMD Radeon OpenGL performance. AMD said this updated closed-source Linux graphics driver would bring "significant performance improvements" for Valve's recently ported Left 4 Dead 2 Linux game. Curious about AMD Linux OpenGL performance improvements elsewhere, I ran some benchmarks of this new driver on several different graphics cards. Unfortunately, the performance improvements aren't too widespread and there's other problems making this beta driver not appealing.

Benchmarking NVIDIA's R310 Linux Driver Improvements

This week NVIDIA began advertising their new "R310" Linux graphics driver that "delivers [a] massive performance boost to Linux gaming" as a result of Valve releasing their Steam Linux Beta. The NVIDIA 310.xx Linux graphics driver not only improves the performance for Valve's Source Engine games, but many Linux OpenGL games. In this article are benchmarks from three graphics cards to highlight the optimizations.
