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.

Ubuntu 12.10: Open-Source Radeon vs. AMD Catalyst Performance

With Ubuntu trying to improve their OpenGL driver support state to push the Linux OS as a platform for gaming, Valve going to be promoting the closed-source NVIDIA and AMD drivers on Linux, and various other challenges still turning up for those trying to use the different Linux OpenGL drivers, here are some new benchmarks comparing the open-source Radeon Gallium3D driver against the closed-source AMD Catalyst driver.

Testing NVIDIA's Linux Threaded OpenGL Optimizations

With the NVIDIA 310.14 Beta driver introduced at the beginning of this week there are some OpenGL performance improvements in general plus an experimental threaded OpenGL implementation that can be easily enabled. In this article are benchmarks from the NVIDIA GeForce GTX 680 with this new Linux driver release.

Gallium3D LLVMpipe On Mesa 9.0

LLVMpipe is gaining traction on the Linux desktop as means of being the default software-accelerated OpenGL fallback. The open-source LLVMpipe driver is even being used for the Unity desktop and GNOME Shell fallback by some distributions when no GPU driver is available (although KDE doesn't plan to take the LLVMpipe route). In this article are benchmarks showing the Gallium3D LLVMpipe performance if attempting to run OpenGL games on this driver running atop a modern CPU.

Nouveau Re-Clocking, NVIDIA vs. Nouveau Drivers

After some dabbling this weekend with Ubuntu 12.10 on both the Nouveau and NVIDIA graphics drivers, there's both good and bad news to share.

Trying Out The Nouveau Driver Rewrite

While Linux 3.7-rc1 hasn't even been released yet as the merge window is still open, the Linux 3.7 kernel is exciting and users of the open-source Nouveau driver will be greeted by the Nouveau DRM driver rewrite / code restructuring. Due to the invasive Nouveau work, some early Nouveau tests under the Linux 3.7 kernel were carried out. The 3.7 results were then compared to the earlier Linux 3.4, 3.5, and 3.6 kernel releases.

Intel Linux OpenGL Driver Remains Slower Than Windows

Recently there was the NVIDIA graphics comparison under Windows 7 and Linux providing new data at how the cross-platform NVIDIA driver is comparing between Ubuntu 12.10, Kubuntu 12.10, and Windows 7 Pro. Aside from Ubuntu's Unity desktop with Compiz impairing the performance, the results were competitive. Next up now is a look at Intel Sandy Bridge and Intel Ivy Bridge graphics when comparing the performance of the three operating systems.

Intel SNA Ivy Bridge - September 2012

Due to the prolific driver development work being done by Intel's Chris Wilson to advance the SNA 2D acceleration architecture for the xf86-video-intel driver, here's some new benchmarks of "Sandy Bridge New Acceleration" when being run from an HD2500-class Core i5 "Ivy Bridge" processor using the new driver release from Sunday.

Intel Graphics Mature Greatly With The Linux Kernel

As a prelude to the forthcoming Windows 7 vs. OS X 10.8 vs. Ubuntu Linux benchmarks that are looking at how Intel OpenGL graphics compare between the operating systems, here's some Intel Sandy Bridge benchmarks that provide a historical look at how the Linux kernel -- and upgrades to the Intel Direct Rendering Manager driver within the kernel -- have matured over time. On average, the Intel Linux graphics performance is up about 30% over the course of the past few kernel releases this year.
