As a follow-up to last week's Ubuntu 14.04 vs. Ubuntu 14.10 AMD Performance Comparison and yesterday's Radeon R9 290: Gallium3D vs. Catalyst driver comparison, here's taking things further in looking at the performance of the open-source AMD Radeon Linux graphics driver in several configurations while compared against the closed-source AMD Catalyst graphics driver as found on Ubuntu 14.10.

Our latest performance benchmarks of last week's release of Ubuntu 14.10 is looking at the performance of an AMD Radeon R9 290 "Hawaii" graphics card using the latest open-source (RadeonSI Gallium3D) graphics driver code compared to the Catalyst driver that's packaged for Ubuntu 14.10. The latest open-source tests do include the in-development Linux 3.18 kernel and Mesa 10.4-devel.

Over the weekend I began posting Ubuntu 14.04 LTS vs. 14.10 benchmarks of the open-source Radeon Gallium3D drivers to show how their software stack has advanced. With our NVIDIA graphics testing it's slightly different since the performance state of Nouveau hasn't changed a lot in the past six months since the re-clocking support overall is still in quite inadequate shape for end-users. However, for some new open-source NVIDIA Linux benchmarks to share today is a look at the open-source NVIDIA (Nouveau) driver performance out-of-the-box on Ubuntu 14.10, then with the Oibaf PPA enabled plus the Linux 3.17 stable kernel, and lastly when using Ubuntu 14.10's supplied NVIDIA proprietary driver.

In comparing the open-source graphics driver performance of Ubuntu 14.04.1 LTS and Ubuntu 14.10, the newer Ubuntu Linux release does offer up some performance improvements to the R600 and RadeonSI graphics drivers, but already in the latest kernel and Mesa Git code is faster performance. Here are benchmarks of Ubuntu 14.04.1 LTS vs. Ubuntu 14.10 for several OpenGL benchmarks with different AMD Radeon graphics cards while also adding in the results of the Oibaf PPA and vanilla Linux 3.17 kernel.

While we're most often looking at the OpenGL 3D performance of the Linux graphics drivers, in the tests currently being done of Ubuntu 14.04 LTS vs. Ubuntu 14.10 are also a number of 2D graphics benchmarks. In the article today are our 2D benchmarks between Ubuntu 14.04.1 and Ubuntu 14.10 for various AMD Radeon graphics cards and it shows off significant performance improvements.

Alex Deucher of AMD has taken the floor at XDC2014, which got underway today in France to provide an update on the company's new unified open-source driver strategy. Compared to what I originally reported earlier in the year when breaking the news, there's some notable changes but overall this is an exciting endeavor for AMD Linux customers with the open and closed source AMD GPU drivers going to share the same (open-source) Linux kernel driver.

Our latest Linux graphics driver benchmarks are taking a look at the binary NVIDIA and AMD Catalyst drivers using the latest versions while running on Ubuntu 14.04 LTS. It's been a while since last time we closely compared the two proprietary GPU drivers with 2D workloads on an array of graphics cards so these results should be definitely interesting.

Last week I published some open-source performance numbers for running the AMD RadeonSI Gallium3D driver at 4K UHD. Today is a performance comparison of the open and closed-source AMD Linux drivers using the latest code atop Ubuntu while running at 3840 x 2160.

For those curious about the performance overhead of enabling multi-sample anti-aliasing (MSAA) with the RadeonSI Gallium3D driver, here are a few benchmarks showing the performance overhead at various MSAA levels with the latest open-source AMD Linux driver.
