After this week having carried out benchmarks showing Intel's Windows 8.1 OpenGL driver is outperforming their open-source Linux driver but NVIDIA's driver on Ubuntu Linux is commonly faster than Windows 8.1, the time has come to benchmark several different AMD Radeon graphics cards under Ubuntu 14.04 LTS and Windows 8.1 Pro x64 with all available updates and each OS using the latest Catalyst 14.4 driver.

The latest Linux graphics testing under the microscope at Phoronix is comparing the Ubuntu 14.04 LTS vs. Windows 8.1 performance with all available updates. Results from Intel, NVIDIA, and AMD hardware is coming up next week while today is a bit of a preview of the AMD numbers when using a Radeon R9 290 "Hawaii" graphics card. While the open-source AMD Hawaii support remains broken, with the Catalyst 14.4 driver on each operating system, the Linux Catalyst driver with the R9 290 graphics card can outperform Windows 8.1 Pro with some OpenGL games and benchmarks.

With Mesa 10.2 just having been branched for its release in the weeks ahead, at Phoronix we have carried out some tests of four different graphics cards when using Mesa 10.1.0 as shipped by Ubuntu 14.04 LTS and then using the Oibaf PPA to upgrade to the latest Mesa 10.3-devel snapshot, which is still close to the state that Mesa 10.2 will be shipping.

Now that we have run the Nouveau open-source NVIDIA tests on the Linux 3.15 kernel and discovered there were no real performance changes for this latest Linux kernel, after finding some Radeon regressions in Linux 3.15, now our attention is on Intel and their Haswell-based HD Graphics. Fortunately, the Intel numbers are slightly more interesting than the Nouveau data.

Following this week's Radeon DRM benchmarks on Linux 3.15, here are benchmarks of the Nouveau open-source NVIDIA Linux graphics driver when using the 3.15 Git kernel compared to stable Linux 3.14.

Our latest focus in benchmarking the Linux 3.15 kernel is the Radeon DRM kernel graphics driver. There's been some reports of small performance changes with this newest kernel currently under development, in part due to some video memory optimizations that landed this cycle. In this article are benchmarks of four AMD Radeon graphics cards when running Linux 3.14 and 3.15 Git.

With Ubuntu 14.04 LTS there is improved support for multi-GPU laptops (commonly what's branded as NVIDIA Optimus configurations) where there is a discrete NVIDIA GPU used for high performance workloads to complement the low-power Intel integrated graphics. Ubuntu 14.04 LTS features better support for these Optimus / DRI PRIME configurations on both the open and closed-source graphics drivers. Here's the Ubuntu 14.04 multi-GPU experience along with some OpenGL benchmarks and power consumption numbers between the different configurations.
