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.
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.

A new patch has surfaced on the Mesa development list that allows for further performance improvements to the R600 Radeon Gallium3D driver for some OpenGL workloads.

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.

For some Sunday benchmarking, here are some results of the different anti-aliasing levels available within NVIDIA's binary Linux graphics driver when using a NVIDIA GeForce GTX 680 "Kepler" graphics card.

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.

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.

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.

At the request of Phoronix readers curious about the NVIDIA VDPAU performance between different GeForce graphics cards, here are some results.

The latest open-source Radeon Linux driver code for supporting the Radeon X1000 (R500) series hardware has basically reached a point of competitiveness with the legacy Catalyst Linux driver that once supported this hardware. In some cases the open-source Gallium3D driver is now faster than what Catalyst once ran at while in other select OpenGL workloads there is still a proprietary imbalance.
