AMD Radeon R600g Gallium3D: Mesa 8.0.4 vs. 8.1 Git

With Mesa 8.1 set to be released next month, here are some benchmarks comparing the Git performance of Mesa 8.0.4 to Mesa 8.1-devel for several generations of Radeon graphics cards. In this article the R600g Gallium3D driver is being put under the microscope while other articles in the coming days will look at the Intel i965 DRI driver, ATI R300g Gallium3D for the older Radeon GPUs, and the Nouveau Gallium3D driver.

The Evolution Of NVIDIA's Kepler Driver Performance

After publishing last week a look at AMD's Catalyst Evolution For The Radeon HD 7000 Series, here's a similar set of benchmarks to see how the NVIDIA graphics driver performance has changed for the GeForce GTX 680 "Kepler" graphics card since its inception.

AMD's Catalyst Evolution For The Radeon HD 7000 Series

It used to be -- at least when using the Windows Catalyst drivers -- that within the first few months of AMD releasing new Radeon graphics hardware that Catalyst driver optimizations would deliver measurable improvements in this short span. For the Radeon HD 7000 series, which is built upon an entirely new GCN architecture, is this still the case? Here are benchmarks of all the AMD Catalyst Linux drivers that have been released this year and then benchmarked on an AMD Radeon HD 7950 graphics card.

The Latest Performance Of Intel Gallium3D

Following the work by Google at the end of June to implement sRGB textures in the Intel i915 Gallium3D driver, new Phoronix benchmarks were conducted to see how the Intel Gallium3D driver now compares performance-wise to the classic i915 driver when using an Intel Atom i945 netbook.

Intel SNA & Glamor Acceleration On Ivy Bridge

Back in May I carried out some performance tests on Intel's Sandy Bridge comparing UXA, SNA, and GLAMOR for 2D acceleration. In this article is a similar set of tests but for Intel's latest-generation Ivy Bridge HD 4000 graphics.

XBMC's Thoughts On XvBA: AMD Catalyst Has Problems

It's not only NVIDIA with Linux problems that cause upstream developers to publicly bash companies, but AMD has come under scrutiny too. The developers of the popular cross-platform XBMC multimedia project shared a little story about enthusiasm, hope, and disappointment. In this guest posting by Peter Fruhberger on Phoronix, XvBA is what is principally talked about, which is AMD's lead choice for video acceleration when using their proprietary Catalyst driver. Unfortunately the XBMC developers aren't too happy about the state of video acceleration using AMD's Catalyst driver for Radeon graphics hardware, hence why they have reached out to Phoronix with this rather lengthy public message. Whether AMD even cares about Linux users and when XvBA will support missing functionality are among their open questions for AMD.

Nouveau Driver Still Tries To Compete With NVIDIA

After sharing the results last week of an optimized open-source Radeon driver trying to compete with AMD's Catalyst driver, it is time to turn the tables. In this article is a look at the latest open-source Nouveau driver code compared to NVIDIA's official closed-source Linux driver across a few generations of GPUs.

An Optimized Open-Source Driver Tries To Compete With AMD Catalyst

There's been a number of recent open-source driver improvements that have come about for modern ATI/AMD Radeon graphics cards under Linux, but not all of these features have yet to be merged or enabled by default (e.g. 2D color tiling, PCI Express 2.0, and HyperZ). With some basic tweaks, can the open-source Radeon Gallium3D driver now compete with AMD's proprietary Catalyst Linux driver when it comes to OpenGL performance? Let's see.
