AMD RadeonSI Graphics Driver Still Troublesome On Linux

Back in June I ran some RadeonSI Gallium3D benchmarks showing the performance had a ways to improve, but sadly the situation hasn't improved months. There's been progress on the RadeonSI Gallium3D driver and from the kernel side with Radeon DRM improvements and new features, but in testing out the latest code it's still a buggy experience and the performance isn't close to matching the closed-source AMD Catalyst Linux graphics driver for Radeon HD 7000 series hardware. At least though for some Linux games we're now in the range of 50% the OpenGL speed of Catalyst.

Intel Iris Pro Linux Performance Doubles With Driver Upgrades

Last week I ran a System76 Galago UltraPro Preview with some benchmark results and a special article looking at the Intel Iris Pro 5200, the Haswell graphics cores with 128MB of dedicated video memory stacked onto the die itself. Those tests were done remotely but now with having a System76 Galago UltraPro ultrabook review sample in the labs, here are some fresh tests looking at the very latest state of Haswell Iris Pro graphics under Linux. The benchmarks cover the state of Ubuntu 13.04 going through the latest open-source Linux graphics driver code with the yet-to-be-released Mesa 9.3 and the Linux 3.12 kernel.

Legacy Radeon Gallium3D Performance Drops On Mesa 9.2

It's been a while since delivering any benchmarks from legacy ATI/AMD Radeon hardware like the X1000 (R500) series on Linux. However, with the release of Mesa 9.2 from late August, here are new benchmarks of the Radeon X1000 series GPUs on the open-source Radeon "R300g" Gallium3D graphics driver.

Radeon R600 Gallium3D MSAA Performance Update

It's been a while since last checking out the multi-sample anti-aliasing (MSAA) performance of the open-source Radeon Gallium3D driver. However, with the recent release of Mesa 9.2, here are new benchmarks of the MSAA Radeon Gallium3D performance from three different AMD graphics cards on Xubuntu Linux.

Intel Haswell Gallium3D OpenGL Benchmarks

Last week support was committed to the mainline Mesa tree for Haswell Gallium3D support via the community-maintained "ILO" driver formerly known as i965g. In this article are the first public benchmarks of the Intel Haswell Gallium3D support code and the performance is compared to the classic i965 Mesa DRI driver that is officially developed by Intel for all modern HD Graphics hardware support.

Mesa 9.2 X.Org/Mir Ubuntu 13.10 Performance Benchmarks

Mesa 9.2 was finally pushed into the Ubuntu 13.10 archive on Thursday and with the upgrade to the open-source 3D graphics library/drivers come many performance improvements and new features. Mesa 9.2 has already been benchmarked extensively on Phoronix, but with its arrival on Ubuntu 13.10, here are some Intel OpenGL benchmarks looking at the performance of Mesa 9.1.6 (Mesa up to now in 13.10 and previously shipped in Ubuntu 13.04) against the new Mesa 9.2.0 release. Testing happened on both an original X.Org Server and then when running both releases on Mir/XMir.

AMD Gallium3D Performance Is Much Better Than Two Years Ago

With the imminent release of Mesa 9.2, out this morning are Radeon "R600" Gallium3D driver benchmarks comparing Mesa Git master (9.3-devel) to Mesa 9.2 Git, Mesa 9.1.6, Mesa 9.0.3, Mesa 8.0.5, and Mesa 7.11.2. These are the past two years worth of Mesa releases and testing occurred on an ATI Radeon HD 4890 (RV790XT) graphics card.

AMD Gallium3D Shader Optimizations Yield Big Gains

With it looking like the R600 SB shader optimization back-end might be enabled for AMD's popular Radeon Gallium3D graphics driver, here are fresh benchmarks looking at the performance impact of enabling this shader optimization code-path that has the ability to dramatically increase the performance out of GLSL-using OpenGL games.

Radeon HD 5000 Series Gallium3D Performance vs. Catalyst

Earlier this week I delivered results showing the AMD Radeon HD 6000 open-source driver becoming more competitive against the proprietary AMD Catalyst driver. The Gallium3D driver is still far from reigning supreme in most aspects that concern desktop Linux users, but much progress has been made in recent months. For those HD 5000 series graphics card owners, here are similar open-source driver vs. AMD Catalyst OpenGL Linux performance tests.

AMD Radeon HD 6000 Series Open-Source Driver Becomes More Competitive

The "R600" Gallium3D driver that provides open-source 3D/OpenGL Linux graphics support for AMD GPUs up through the Radeon HD 6000 graphics cards is becoming increasingly competitive. The open-source AMD stack isn't yet ready to overtake the proprietary AMD Catalyst driver in terms of raw performance or OpenGL compliance, but a lot of ground has been made up in recent months.
