RadeonSI Color Tiling Brings OpenGL Performance Boost

A few days back I delivered a fresh round of RadeonSI Gallium3D benchmarks showing the open-source AMD Radeon driver improving but still a long shot from the Catalyst driver. Shortly thereafter, it was announced the open-source driver would enable 2D color tiling by default. As earlier Phoronix benchmarks have shown, color tiling can be a big performance win so over the weekend I carried out some new performance tests looking at the impact of enabling color tiling for the RadeonSI driver that supports the HD 7000/8000 series and Rx 200 series graphics processors.

AMD's RadeonSI Gallium3D Is Improving, But Catalyst Is Much Better

After last week delivering a Linux hardware review of the AMD Radeon R9 270X graphics card with the binary Catalyst driver on Ubuntu, and then yesterday looking at the Radeon Gallium3D driver posing a threat to Catalyst when using the mature "R600g" driver on HD 5000/600 series hardware, up today are new open vs. closed-source benchmarks. In this article we're looking at the performance of the Radeon R9 270X GPU when using the Ubuntu 13.10 open-source graphics stack, then when upgrading to Mesa 10.0 with Linux 3.12 DPM, and then comparing those numbers to the proprietary Catalyst Linux graphics driver.

Nouveau vs. NVIDIA Linux vs. NVIDIA Windows 8.1

A few days back I delivered benchmark results of a 13-way graphics card comparison comparing the OpenGL gaming performance between Ubuntu Linux and Microsoft Windows 8.1. In that article there were multiple AMD Radeon and NVIDIA GeForce graphics cards tested using the binary drivers for each operating system. On Wednesday I then shared results with the Radeon Gallium3D driver compared to Catalyst on Linux and Windows while today are some of the early Nouveau results compared to the proprietary NVIDIA GPU drivers on Windows and Linux.

AMD's Radeon Gallium3D Starts Posing A Threat To Catalyst

With recent milestones like the Radeon performance improvements in Linux 3.12 that come as a side-effect from a CPUfreq change, Radeon DPM, and the improvements found by the upcoming Mesa 10.0 release, and numerous other open-source driver improvements, the AMD's Radeon Gallium3D performance is very competitive to AMD's Catalyst driver. This close level of performance is for the R600 Gallium3D driver with GPUs like the Radeon HD 5000/6000 series graphics cards. Here's some benchmarks showing how the open-source AMD Radeon performance compares today to the closed-source Catalyst driver on Windows and Ubuntu Linux. In some of today's new data, the open-source driver was running 80%+ the speed of AMD's Catalyst driver.

Open-Source Nouveau Driver Remains Slow For NVIDIA's Fermi, Kepler

After last week publishing a Linux review of the GeForce GTX 650 using the proprietary NVIDIA Linux graphics driver, I set out to run a new performance comparison of the open-source "Nouveau" graphics driver against NVIDIA's official closed-source Linux driver. In this comparison, five different GeForce 400/500 "Fermi" and GeForce 600 "Kepler" graphics cards were benchmarked under Ubuntu Linux on each driver.

7-Way Low-End Open-Source Linux GPU Comparison

If you're in the market for a low-end graphics processor that's compatible with Linux and the available open-source Mesa/Gallium3D graphics drivers, here's a roundup of benchmark results for seven different AMD, Intel, and NVIDIA graphics processors.

Linux 3.12 Can Change AMD's Catalyst Performance

Due to a change found in the Linux 3.12 kernel, the AMD Radeon GPU performance is a lot faster with the open-source driver for certain configurations and the Nouveau driver performance is also faster depending upon the CPU and GPU. Now the latest in comparing the Linux 3.11 and 3.12 kernel performance, I can confirm some small performance changes with the binary Catalyst driver.

The AMD Radeon Performance Is Incredible On Linux 3.12

Over the weekend I released benchmarks showing the Linux 3.12 kernel bringing big AMD Radeon performance improvements. Those benchmarks of a Radeon HD 4000 series GPU showed the Linux 3.12 kernel bringing major performance improvements over Linux 3.11 and prior. Some games improved with just low double-digit gains while other Linux games were nearly 90% faster! Interestingly, the AMD Radeon Linux developers were even surprised by these findings. After carrying out additional tests throughout the weekend, I can confirm these truly incredible performance improvements on other hardware. In this article are results from ten different AMD Radeon graphics cards.

Linux 3.12 Brings Big AMD Radeon Improvements

The Linux 3.12 kernel when released in the coming weeks will bring a number of new features and improvements to AMD Radeon graphics cards, including faster performance. For many Linux games tested the Radeon Gallium3D OpenGL frame-rates were making double-digit gains through upgrading the Linux kernel.

AMD R600 Gallium3D Performance Changes Found On Mesa 9.3

While there's at least another month left until the release of Mesa 9.3 / Mesa 10.0, for the mature Radeon R600 Gallium3D there are already a number of performance changes -- for both good and bad -- that can be spotted in running the latest code. Here's some benchmarks showing some of the performance changes over Mesa 9.2.1 stable for a Radeon HD 4000 series GPU on the open-source AMD Linux GPU driver.
