Oibaf Keeps Making Ubuntu GPU Driver Upgrades Easy

For those that may have some time this holiday weekend and are looking to better enhance the performance of Ubuntu's open-source graphics drivers, one of the easiest ways to do so is by enabling the Oibaf repository for easily downloading and installing newer versions of the Mesa/Gallium3D drivers and other X.Org related components. Here are some more details and current benchmarks of enabling the Oibaf PPA over Ubuntu 13.10.

13-Way NVIDIA VDPAU Video Decode Benchmarks

It's been a while since last putting out any hardware-accelerated video decode benchmarks of NVIDIA's Video Decode and Presentation API for Unix (VDPAU). However, after updating qVDPAUtest to support building on modern platforms, here's a round of thirteen NVIDIA GeForce graphics cards being benchmarked under VDPAU.

Linux 3.0, 3.4, 3.10, 3.12 AMD Kernel Benchmarks

How does the Linux kernel performance compare if simply bouncing between some of the recent long-term kernel releases? Well, to try to answer that question on Phoronix today we have benchmarks of the Linux 3.0.101, 3.4.68, 3.10.18, and 3.12.0 kernel releases tested from an AMD Opteron system with Radeon graphics.

Running The Latest GNOME Wayland Shell On Fedora 20

With the Fedora 20 beta coming up I decided to see where the latest Fedora 20 packages are now at for their support of Wayland and the GNOME Shell Wayland session. In particular, looking at whether the session is still buggy and how the XWayland performance is for Linux gaming.

XMir Performance Measured On Ubuntu 13.10

While the Ubuntu 13.10 desktop isn't using Mir/XMir by default, the packages are available within the archive for those wanting to test out the next-generation display server for Ubuntu. To see how the 2D/3D performance is when running under XMir with the Unity System Compositor, I ran some new benchmarks using this week's Ubuntu 13.10 release.

Liquorix 3.11 Kernel Benchmarks

It's been several kernel releases since last benchmarking the Liquorix kernel, an optimized version of the Linux kernel that's advertised as "built using the best configuration and kernel sources for desktop, multimedia, and gaming workloads." In Liquorix having out their version of the Linux 3.11 kernel since late September, here are some benchmarks comparing Liquorix to recent mainline versions of the vanilla Linux kernel.

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.

GCC vs. LLVM Clang Is Mixed On The Ivy Bridge Extreme

Our latest Linux benchmarks from the Intel Core i7 4960X Ivy Bridge Extreme Edition processor are compiler tests on this $1000 USD processor. The last two stable releases of GCC and LLVM's Clang C/C++ compilers were compared: GCC 4.7.2, GCC 4.8.1, LLVM Clang 3.2, and LLVM Clang 3.3.
