As promised, now that Linux 3.11-rc1 has been released, it's time for the new dynamic power management support of the Linux 3.11 kernel for AMD Radeon graphics. This first article previews the possible OpenGL performance gains for an AMD APU when enabling "DPM" for allowing the graphics core to properly re-clock based upon its workload.

For those with older generations of AMD/ATI Radeon graphics processors that may not be running the very latest Mesa Gallium3D driver release, here are benchmarks comparing every major Mesa release between Mesa 7.11 and Mesa 9.2.

From the AMD A10-6800K "Richland" APU I've delivered OpenGL Linux benchmarks of the Radeon HD 8670D graphics and also compared the open-source Gallium3D performance to that of Catalyst. Catalyst still reigns supreme, but in this article are some benchmarks showing the performance between Mesa 9.1 and 9.2 Git and also when deploying the experimental R600 SB shader optimization back-end.

After recently delivering a 15-way open-source Intel/AMD/NVIDIA GPU comparison, here are the benchmarks when tossing in the proprietary AMD Catalyst and NVIDIA graphics drivers too. Besides comparing a diverse selection of graphics processors from the three main desktop GPU vendors, this comparison also shows how the current open-source Linux graphics drivers compare to the official proprietary drivers.

With the Linux 3.10 kernel having been pulled recently into the Ubuntu 13.10 archive, new benchmarks have been conducted comparing the open-source Nouveau driver against the binary NVIDIA 319.32 Linux graphics driver on a NVIDIA-powered laptop.

This morning there were the RadeonSI Gallium3D vs. AMD Catalyst Linux benchmarks for the high-end Radeon HD 7850/7950 "Southern Islands" graphics cards. While the new Southern Islands GPUs understandingly have a long way to catch up on their new open-source Linux Gallium3D driver compared to Catalyst, how is the AMD Radeon HD 8670D "Richland" APU performance between the open and closed-source drivers? Here are some benchmarks.

Towards the end of June I published AMD RadeonSI Gallium3D benchmarks, the open-source Linux graphics driver supporting the Radeon HD 7000/8000 series hardware on Linux. While the alternative to the Catalyst driver can accelerate OpenGL, it's very slow. Open-source driver benchmarks were shown in that article compared to older generations of AMD Radeon hardware backed by the mature R600 Gallium3D driver. In this article are benchmarks comparing the open-source "RadeonSI" driver to the proprietary AMD Catalyst GPU driver on the Radeon HD 7850/7950 graphics cards. As an additional driver reference point were also Radeon HD 7950 Cayman results; all testing happened from Fedora 19 Linux.

With Fedora 19 presenting a nice "out of the box" experience for AMD Radeon HD 7000 series graphics using the open-source RadeonSI Gallium3D driver, benchmarks of the open-source driver were done and compared to previous generations of AMD hardware. Sadly, there's still much work ahead for the Radeon HD 7000 series driver in being able to catch up with the hardware supported under the mature R600 Gallium3D driver.

With Thursday's announcement that Mir will ship by default in Ubuntu 13.10 on the desktop, many Ubuntu users were caught by surprise that this experimental display server will be ready by October. Up to now, Ubuntu 13.10 was expected to continue using an X.Org Server by default on the desktop (with only an experimental option for Mir) while the new Ubuntu Touch project would be using Mir on mobile devices, until next year. With the pressed timeline for the migration to Mir, at Phoronix we have already carried out our first Mir benchmarks. In this article are the first benchmarks of Intel graphics when running on Ubuntu 13.10 with a native X.Org Server (as done now on current Ubuntu Linux releases) and then when deploying the same Unity desktop environment atop XMir with the Mir unity-system-compositor.

To complement the Intel Haswell Linux OpenGL benchmarks that we have been publishing on Phoronix for the past week, up today are some Intel Linux 2D performance benchmarks of Haswell with the Intel Core i7 4770K CPU. The 2D performance is comparing Intel's default UXA accelerated code-paths against the experimental SNA acceleration back-end.
