AMD APU On Linux: Gallium3D Can Be 80%+ As Fast As Catalyst

After running earlier this week a 21-way graphics card comparison with Intel, AMD, and NVIDIA GPUs, there were requests by some Phoronix readers to see some new APU performance numbers. For ending out November, here's new Catalyst vs. Gallium3D driver benchmarks on Ubuntu Linux for the AMD A10-6800K with its Radeon HD 8670D graphics. The results with the latest Linux kernel and Mesa are very positive towards the open-source AMD driver where in some tests the performance can nearly match Catalyst! For at least one Source Engine game, the open-source driver can now even run significantly faster than the binary driver.

21-Way Open-Source AMD/Intel/NVIDIA GPU Benchmarks On Linux

If you are hoping to snag some deals on computer hardware this holiday shopping season, for helping guide you in any graphics card purchases are a fresh round of benchmarks of 21 different graphics processors from the Intel HD Graphics, AMD Radeon, and NVIDIA GeForce families tested on their respective open-source Linux graphics drivers.

Open-Source NVIDIA Driver Works On Some GeForce 700 GPUs

With being in the process of checking out several new NVIDIA GeForce 700 GPUs on Linux, now that I have out of the way the GeForce GTX 760 / 770 / 780 Ti / TITAN Linux benchmarks and Windows vs. Linux NVIDIA benchmarks, I decided to see how these four "Kepler" graphics cards are working with Nouveau, the open-source NVIDIA graphics driver that's written through clean-room reverse-engineering. Up until recently Nouveau has just been an open-source community project, except now NVIDIA is beginning to support Nouveau and open-source, so let's see how it runs on this latest high-end graphics hardware.

8-Way AMD Gallium3D vs. Catalyst Ubuntu GPU Benchmarks

While I'm now onto benchmarking several new NVIDIA graphics cards under Linux and also the AMD Radeon R9 290, earlier this week I ran some more open-source vs. closed-source driver benchmarks on Ubuntu Linux. Here's fresh benchmark results when comparing eight AMD Radeon graphics cards on the open (Gallium3D) and closed-source (Catalyst) drivers and running various Linux OpenGL workloads.

Radeon Gallium3D Improvements Compared To Legacy Catalyst

Recently I published OpenGL benchmark results on Phoronix showing the open-source R600 Gallium3D driver competing with Catalyst for Radeon HD 5000/6000 series graphics cards. For the Radeon HD 7000 series and newer "GCN" graphics cards that are supported by the different RadeonSI driver, the performance has a ways to improve. What wasn't included with those recent Phoronix articles were looking at the performance for the Radeon HD 4000 series GPUs, which is now only supported by the open-source driver and the Catalyst Legacy driver that doesn't work on modern Linux distributions. Therefore, for this article we're looking at the Catalyst Legacy performance on Ubuntu 12.10 (as well as its open-source R600g driver at the time) and compare it to the OpenGL performance found out of the box on Ubuntu 13.10 and then with the latest Linux 3.12 and Mesa 10.0 driver code.

AMD RadeonSI GLAMOR 2D Benchmarks

For kicking off a new week of Linux benchmarking, to share today are benchmarks looking at three Radeon HD 7000 / Radeon Rx 200 series graphics cards on Ubuntu Linux when looking at the GLAMOR acceleration architecture performance with xf86-video-ati when compared to the proprietary Catalyst driver on the same hardware.

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.
