AMD A10-7870K Godavari: RadeonSI Gallium3D vs. Catalyst Linux Drivers

Last week I started posting AMD A10-7870K Linux benchmarks for this "Godavari" APU that's effectively a Kaveri Refresh and slightly faster for its four CPU cores and Radeon R7 Graphics over the former high-end Kaveri, the A10-7850K. In today's articles are some benchmarks of the Radeon R7 Graphics on the A10-7870K when running Ubuntu and testing the open-source RadeonSI Gallium3D driver against Catalyst on Linux.

Catalyst 15.5 For Linux Brings Some Performance Improvements

Earlier this month Catalyst 15.5 was released for Linux as the first official Linux graphics driver update since last December when Catalyst 14.12 was released (sans the special fglrx driver packaged by Canonical for Ubuntu 15.04). As discussed by users in our forums and elsewhere, Catalyst 15.5 does offer better performance for certain OpenGL workloads compared to the earlier driver, but the gains aren't universal.

Intel Sandy Bridge Linux Graphics Benchmarks Over The Past Three Years

As another large, historical test in celebrating Phoronix's 11th birthday this month, here are some benchmarks looking at the Intel Sandy Bridge HD Graphics 2500 performance on Ubuntu Linux over the past three years. Every Ubuntu Linux release from 12.10 to 15.04 was tested, plus the latest Linux kernel and Mesa Git code.

Benchmarks Of The Open-Source Intel/AMD/NVIDIA Drivers, 11 Years On

In celebrating 11 years since starting Phoronix to cover the Linux hardware scene, here's some fresh benchmarks of the open-source Intel / AMD / NVIDIA Linux graphics drivers. Various GPUs were tested atop Ubuntu when moving to Git with the Linux 4.1 kernel, Mesa 10.7-devel, and LLVM 3.7 SVN.

Intel Iris Graphics Performance With Mesa 10.6

With Mesa 10.6 due to be released in early June, our usual performance comparisons of this new Mesa 3D version will come. To get our latest round of Mesa open-source graphics driver benchmarking kicked off, here are benchmarks of Intel's Iris Graphics when comparing Mesa 10.5 and 10.6 Git atop Ubuntu 15.04.

GeForce GTX 750 Series: Nouveau vs. NVIDIA Linux Driver Performance

With the forthcoming Linux 4.1 kernel there is finally out-of-the-box acceleration for the NVIDIA GeForce GTX 750 series on the Nouveau driver. With the Nouveau DRM/KMS driver able to self-generate the needed firmware/microcode to enable acceleration, it's quite easy to get running. However, the performance leaves a lot to be desired.

GLAMOR + RadeonSI 2D Acceleration Is Quite Good For Open-Source AMD 2D Performance

Yesterday I posted some benchmark results showing the AMD Radeon R9 290 graphics card on Ubuntu 15.04 and comparing the Catalyst driver to the open-source RadeonSI Gallium3D driver as found on this new Linux distribution release. The previous article focused on the OpenGL performance while today's article is looking squarely at the 2D performance.

AMD Radeon R9 290 OpenGL On Ubuntu 15.04: Catalyst vs. RadeonSI Gallium3D

While I've posted some new AMD OpenGL benchmarks on Ubuntu 15.04 since last week's release of the Vivid Vervet, the Radeon R9 290 wasn't tested since at that time this Hawaii graphics card was busy on other Phoronix test systems. However, due to the interest level in seeing some fresh Ubuntu 15.04 numbers for the Radeon R9 290 series, here's some numbers.

Ubuntu 15.04 Offers Faster OpenGL For AMD Radeon GPUs On Open-Source

Intel Haswell Linux users are greeted by relatively modest performance changes with Ubuntu 15.04 while those using AMD Radeon graphics cards on the open-source R600 and RadeonSI Gallium3D drivers have much more to look forward to when upgrading to this week's release of Ubuntu 15.04. Here's some Ubuntu 14.10 vs. Ubuntu 15.04 OpenGL benchmarks for a range of AMD Radeon graphics cards.

Radeon Linux Benchmarks: Catalyst 15.3 Beta vs. Linux 4.0 + Mesa 10.6-devel

Before ending out March, here's some new OpenGL Linux benchmarks comparing the closed-source Catalyst 15.3 Beta driver against the Linux 4.0 development kernel with Mesa 10.6 Git for the freshest open-source graphics driver code.
