With the Linux 3.17 kernel, Mesa 10.3, and the newest Radeon microcode files, there's finally working Hawaii GPU support by AMD's open-source Linux graphics driver. The Radeon R9 290 series launched nearly one year ago and finally now the open-source driver is working right, so we've conducted some preliminary tests using the R9 290 compared to AMD's other Radeon GPUs on the open-source Linux driver.

Earlier this week I ran the article about open-source Radeon graphics having some improvements with Linux 3.17 but after further testing of a range of AMD GPUs spanning multiple generations, for not all hardware are AMD graphics cards faster with this experimental kernel. In this article are benchmarks of the Linux 3.17 kernel with Mesa 10.3-devel showing the winners and losers from the Radeon HD 5000 series through the latest Radeon Rx 200 series graphics cards.

Compared to the state of AMD's RadeonSI Gallium3D driver stack shipped in Ubuntu 14.04 LTS back in April, the latest open-source graphics driver code for the Radeon HD 7000 series GPUs and newer is a heck of a lot faster. Here's some tests showing how much progress has been made the past few months.

Besides the recent work to support OpenGL Geometry Shaders for Sandy Bridge in Mesa, users of Intel "Sandy Bridge" HD Graphics can also be thankful for the forthcoming Linux 3.17 kernel. Early testing of Linux 3.17 has revealed that for at least some Intel Sandy Bridge hardware are OpenGL performance improvements with the newer kernel code.

With this week's Catalyst vs. RadeonSI Gallium3D driver comparison for the A10-7800 Kaveri APU with Radeon R7 Graphics, the default driver settings were used since after all it's what most Linux gamers and desktop users will utilize when running either driver. However, for those wanting to tune their open-source driver to get a bit higher number, enabling HyperZ is still an easy win.

With the recently released AMD A10-7800 Kaveri APU I carried out some new benchmarks comparing the open and closed-source Linux GPU driver performance for AMD with their Catalyst and RadeonSI Gallium3D solutions. When running the open-source Ubuntu driver tests, multiple versions of Mesa and the Linux kernel were used.

After last week running new Nouveau vs. NVIDIA proprietary Linux graphics benchmarks, here's the results when putting AMD's hardware on the test bench and running both their latest open and closed-source drivers. Up today are the results of using the latest Radeon Gallium3D graphics code and Linux kernel against the latest beta of the binary-only Catalyst driver.
