Yesterday on Phoronix I published results showing the Radeon Gallium3D performance getting close to Catalyst for the Radeon HD 5000 series and newer GPUs that are supported by the mainline Catalyst driver. On the open-source side the hardware is supported by the R600 and RadeonSI (for the GCN hardware) Gallium3D drivers. Yesterday's results showed that on Ubuntu 14.04 for many OpenGL workloads the R600/RadeonSI Gallium3D drivers were now ~80% the speed of the proprietary Catalyst driver in many instances. While this is a great feat, how does it stand for older generations of AMD Radeon hardware? In this article are Radeon HD 4870 benchmarks looking at the performance of the open-source AMD Linux driver over three years of Ubuntu Linux releases and compared to the legacy Catalyst driver from 2011.

With the open-source graphics driver stack found in the forthcoming release of Ubuntu 14.04 LTS (Mesa 10.1 + Linux 3.13), the performance of the community-developed Radeon Gallium3D driver is now close to that of the official AMD Catalyst driver for recent generations of Radeon graphics cards. In several OpenGL tests the "RadeonSI" driver can even run 80% the speed of AMD's official Catalyst Linux driver.

For anyone currently experiencing a slowdown of their Radeon Gallium3D open-source driver stack or are interested in helping out track down a new performance issue, it appears the Linux 3.14 + Mesa 10.2 configuration is regressing on Ubuntu 14.04 LTS in place of Linux 3.13 + Mesa 10.1.

With the imminent release of Mesa 10.1 and Ubuntu 14.04 LTS landing this updated open-source 3D graphics stack at the last minute, here are some benchmarks of this preliminary open-source GPU driver stack of Ubuntu 14.04 with Mesa 10.1 and the Linux 3.13 kernel. With Mesa 10.1 there is now also Unigine Heaven & Valley benchmarks that are now compatible with the Radeon Gallium3D drivers.

In finding it interesting that the Radeon HD 8210 Gallium3D performance can outperform Catalyst from an AMD E1-2100 "Kabini" low-end APU, which was tested on an ECS KBN-I Kabini system that can be found for just over $30 USD when on sale, it's time for some more Linux benchmarks. The latest tests from this low-end but fascinating platform are benchmarking a variety of PCI-E graphics cards on this AMD Kabini platform using the open-source Radeon and Nouveau graphics drivers on Ubuntu 14.04.

For those curious how AMD's Catalyst Linux performance is doing as we get 2014 underway with the first Catalyst 14.1 beta, here are benchmarks from nine different AMD Radeon graphics cards under Ubuntu Linux and running this latest publicly available driver when looking at both the OpenGL graphics and OpenCL compute performance.

Some of our final Linux benchmarks at Phoronix to end out January are of looking at the Mesa 10.0 vs. 10.1-devel performance for Intel HD Graphics 4600 on a Core i5 processor while running Ubuntu 14.04. Is there much in store for Haswell with this upcoming three-month update to Mesa?

Earlier this month I shared some basic OpenGL benchmarks between AMD's Kaveri APU on the Catalyst driver and the open-source RadeonSI Gallium3D driver. Now that more time has passed I'm back with another round of Linux graphics driver testing on the AMD A10-7850K, this time looking at the impact when forcing Dynamic Power Management and toggling color tiling for maximum performance.

Nouveau, the reverse-engineered open-source NVIDIA Linux graphics driver that's been in development now for the better part of a decade, is working brilliantly for some NVIDIA GeForce graphics cards while for other NVIDIA GPUs the experience is a sloppy mess. Using the Linux 3.13 kernel and Mesa 10.1-devel Gallium3D driver code installed on top of Ubuntu 13.10, here's what the experience is like when trying a number of GeForce graphics cards with this latest open-source driver code.

Yesterday I ran the latest RadeonSI Gallium3D vs. Catalyst AMD Linux driver comparison, effectively another round of open-source vs. closed-source GPU driver testing. In yesterday's article it was found the RadeonSI performance is improving a lot but the AMD Catalyst Linux driver remains much faster. In this article are benchmarks of the older "R600" Radeon Gallium3D driver compared to the Catalyst driver with graphics cards from the Radeon HD 6000 series and older where the open-source R600g driver provides support and in a more mature state.
