With recent milestones like the Radeon performance improvements in Linux 3.12 that come as a side-effect from a CPUfreq change, Radeon DPM, and the improvements found by the upcoming Mesa 10.0 release, and numerous other open-source driver improvements, the AMD's Radeon Gallium3D performance is very competitive to AMD's Catalyst driver. This close level of performance is for the R600 Gallium3D driver with GPUs like the Radeon HD 5000/6000 series graphics cards. Here's some benchmarks showing how the open-source AMD Radeon performance compares today to the closed-source Catalyst driver on Windows and Ubuntu Linux. In some of today's new data, the open-source driver was running 80%+ the speed of AMD's Catalyst driver.

After last week publishing a Linux review of the GeForce GTX 650 using the proprietary NVIDIA Linux graphics driver, I set out to run a new performance comparison of the open-source "Nouveau" graphics driver against NVIDIA's official closed-source Linux driver. In this comparison, five different GeForce 400/500 "Fermi" and GeForce 600 "Kepler" graphics cards were benchmarked under Ubuntu Linux on each driver.

Due to a change found in the Linux 3.12 kernel, the AMD Radeon GPU performance is a lot faster with the open-source driver for certain configurations and the Nouveau driver performance is also faster depending upon the CPU and GPU. Now the latest in comparing the Linux 3.11 and 3.12 kernel performance, I can confirm some small performance changes with the binary Catalyst driver.

Over the weekend I released benchmarks showing the Linux 3.12 kernel bringing big AMD Radeon performance improvements. Those benchmarks of a Radeon HD 4000 series GPU showed the Linux 3.12 kernel bringing major performance improvements over Linux 3.11 and prior. Some games improved with just low double-digit gains while other Linux games were nearly 90% faster! Interestingly, the AMD Radeon Linux developers were even surprised by these findings. After carrying out additional tests throughout the weekend, I can confirm these truly incredible performance improvements on other hardware. In this article are results from ten different AMD Radeon graphics cards.

The Linux 3.12 kernel when released in the coming weeks will bring a number of new features and improvements to AMD Radeon graphics cards, including faster performance. For many Linux games tested the Radeon Gallium3D OpenGL frame-rates were making double-digit gains through upgrading the Linux kernel.

While there's at least another month left until the release of Mesa 9.3 / Mesa 10.0, for the mature Radeon R600 Gallium3D there are already a number of performance changes -- for both good and bad -- that can be spotted in running the latest code. Here's some benchmarks showing some of the performance changes over Mesa 9.2.1 stable for a Radeon HD 4000 series GPU on the open-source AMD Linux GPU driver.

With most of the exciting Intel Mesa open-source Linux graphics driver updates being now about Haswell or Bay Trail (Valley View), it's been a while since last publishing any benchmarks of previous-generation Intel "Sandy Bridge" and "Ivy Bridge" graphics results with the latest open-source driver code. Changing that, today are benchmarks of several different Intel Sandy Bridge and Ivy Bridge processors when running Ubuntu 13.10 with the Linux 3.11 kernel and Mesa 9.2.

Earlier this month I published benchmarks of Intel's Iris Pro 5200 graphics when comparing the Intel driver performance between Windows 8 and Ubuntu Linux. The test results found that there were some performance wins for Intel OpenGL on Linux after the very latest open-source driver optimizations were made, but there are still some losses. In this article are a few more Windows 8 vs. Linux benchmark results for the Haswell Ultrabook with Iris Pro graphics.

Earlier this week on Phoronix were the results of an 11-way AMD Radeon GPU comparison using the Linux 3.12 kernel and Mesa 9.3-devel. Coming out today are the results for a four-way NVIDIA GeForce graphics card comparison using the Nouveau driver on Linux 3.12 / Mesa 9.3-devel. Sadly, this comparison is smaller than the open-source Radeon comparison since the reverse-engineered Nouveau driver was very buggy in its current configuration.
