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.

Clock-For-Clock, Nouveau Can Compete With NVIDIA's Driver

Similar to last week's testing of comparing the open-source vs. closed-source Radeon Linux driver performance from a stock Ubuntu 12.10 installation, the tables have now been turned to look at NVIDIA hardware on this latest Ubuntu Linux release. Benchmarks were done of the stock Nouveau open-source graphics driver, the official NVIDIA proprietary driver, and the proprietary driver when it was underclocked to match the clock frequencies as used by the reverse-engineered Nouveau driver.

Radeon Gallium3D R600g Color Tiling Performance

With 2D color tiling enabled by default in the R600 Gallium3D Radeon open-source driver as of this week, here are new benchmarks showing off the OpenGL performance impact of the 1D and 2D tiling methods for this common open-source AMD Linux graphics driver.

AMD R600g Performance Patches Yield Mixed Results

Following performance benchmark results I published earlier this week comparing the open-source Radeon and AMD Catalyst driver performance under Ubuntu 12.10, Marek, the well-known independent open-source graphics driver developer, set out to explore some of the performance issues in the open-source driver. One day later, he published a patch that could quadruple the frame-rate of the Radeon Gallium3D driver. He went on to push another performance-focused patch too for this R600g driver. In this article are a fresh round of benchmarks of the open-source driver to look at the wins and losses attributed to this new code.
