Nouveau Performance Is Faster With Linux 3.12

In following the AMD Radeon performance is incredible on Linux 3.12 article that benchmarked ten different AMD graphics cards on the Linux kernel, followed by the reason why AMD Radeon graphics are faster on Linux 3.12, here's now some benchmarks of the open-source NVIDIA driver with GeForce graphics cards. The testing in this article is a few NVIDIA GeForce graphics cards with the Nouveau driver when comparing the Linux 3.11 and 3.12 kernels in a similar fashion to the AMD Linux OpenGL performance testing. Like the AMD results, there are some notable gains to find with the yet-to-be-released 3.12 kernel.

Here's Why Radeon Graphics Are Faster On Linux 3.12

Yesterday I published benchmarks showing the AMD Radeon graphics being much faster on Linux 3.12. Ten graphics cards were benchmarked and many of them were showing rather remarkable OpenGL frame-rate performance improvements when moving from the Linux 3.11 to Linux 3.12 Git kernel. This large comparison came after benchmarks I did this weekend on a single Radeon HD graphics card showed the Linux 3.12 kernel delivering the best performance of any recent kernel release. The only thing was, this AMD Radeon performance improvement baffled the upstream developers. The AMD developers were taken off-guard and didn't have an explanation why the Linux 3.12 kernel performance is faster... Now thanks to automated testing and bisecting by the Phoronix Test Suite, I have an answer.

Intel Core i7 Haswell Benchmarks On Linux 3.12

So far in our testing of the Linux 3.12 kernel we have found that there are some file-system performance improvements and most noticeable is AMD Radeon performance improvements for the open-source driver. We have also found the AMD APU performance hasn't changed much and Ivy Bridge graphics are rather unchanged among other mute workloads, but is there any other worthwhile performance improvements to be discovered? Our latest Linux 3.12 Git tests are from the System76 Galago UltraPro with Core i7 4750HQ "Haswell" processor as we benchmark every major kernel release going back to Linux 3.8.

Unity On XMir Performance For Nouveau Gallium3D

On Friday I delivered the first benchmarks of Ubuntu's Unity desktop running on XMir -- the X.Org Server compatibility layer for talking to the Mir Display Server. Those benchmarks showered there was noticeable performance overhead to running XMir with Intel's graphics driver. Later benchmarks showed XMir 2D performance was also negatively affected. In this article are benchmarks looking at the XMir performance with the Nouveau driver.

2D Performance Also Impacted By Unity On XMir

Earlier today I delivered the first benchmarks of Ubuntu's Unity 7 running over XMir to run the current X11 desktop atop the Mir Display Server via this compatibility layer. These benchmarks documented the performance impact of running OpenGL games when having to deal with XMir rather than just a clean X.Org Server running on the hardware. The extra step in the rendering process did result in a measurable performance impact, especially when the performance of the open-source Linux graphics drivers is already lower than their proprietary brethren. The benchmarks to now show illustrate that the 2D rendering performance also takes a hit when running Unity on XMir.
