AMD Radeon R9 290 Open-Source Driver Works, But Has A Ways To Go

With the Linux 3.17 kernel, Mesa 10.3, and the newest Radeon microcode files, there's finally working Hawaii GPU support by AMD's open-source Linux graphics driver. The Radeon R9 290 series launched nearly one year ago and finally now the open-source driver is working right, so we've conducted some preliminary tests using the R9 290 compared to AMD's other Radeon GPUs on the open-source Linux driver.

Radeon Graphics Yield Mixed Results With Linux 3.17 Kernel

Earlier this week I ran the article about open-source Radeon graphics having some improvements with Linux 3.17 but after further testing of a range of AMD GPUs spanning multiple generations, for not all hardware are AMD graphics cards faster with this experimental kernel. In this article are benchmarks of the Linux 3.17 kernel with Mesa 10.3-devel showing the winners and losers from the Radeon HD 5000 series through the latest Radeon Rx 200 series graphics cards.

Intel Sandy Bridge Gets A Surprise Boost From Linux 3.17

Besides the recent work to support OpenGL Geometry Shaders for Sandy Bridge in Mesa, users of Intel "Sandy Bridge" HD Graphics can also be thankful for the forthcoming Linux 3.17 kernel. Early testing of Linux 3.17 has revealed that for at least some Intel Sandy Bridge hardware are OpenGL performance improvements with the newer kernel code.

Enabling HyperZ Is Still An Easy Way For Faster RadeonSI Performance

With this week's Catalyst vs. RadeonSI Gallium3D driver comparison for the A10-7800 Kaveri APU with Radeon R7 Graphics, the default driver settings were used since after all it's what most Linux gamers and desktop users will utilize when running either driver. However, for those wanting to tune their open-source driver to get a bit higher number, enabling HyperZ is still an easy win.

AMD Kaveri: Catalyst vs. RadeonSI Gallium3D On Linux

With the recently released AMD A10-7800 Kaveri APU I carried out some new benchmarks comparing the open and closed-source Linux GPU driver performance for AMD with their Catalyst and RadeonSI Gallium3D solutions. When running the open-source Ubuntu driver tests, multiple versions of Mesa and the Linux kernel were used.

Radeon Gallium3D Is Running Increasingly Well Against AMD's Catalyst Driver

After last week running new Nouveau vs. NVIDIA proprietary Linux graphics benchmarks, here's the results when putting AMD's hardware on the test bench and running both their latest open and closed-source drivers. Up today are the results of using the latest Radeon Gallium3D graphics code and Linux kernel against the latest beta of the binary-only Catalyst driver.

AMD Catalyst 14.6 Does Slightly Better With APITest OpenGL Tests

Last month I published some benchmarks where NVIDIA slaughtered AMD's Catalyst driver in APITest benchmarks, a set of OpenGL 4.x test cases. While these are just micro-benchmarks of modern OpenGL and designed for showing off potential solutions for problems to leading to lower driver overhead, there's been some improvements within the Catalyst 14.6 Beta on Linux. Up today are some new benchmarks of APITest using the latest AMD and NVIDIA drivers.

Even With Re-Clocking, Nouveau Remains Behind NVIDIA's Proprietary Linux Driver

Starting out the last week of July's Linux benchmarking on Phoronix is a fresh comparison of several NVIDIA GeForce graphics cards when comparing the performance of the latest open-source Nouveau driver against the latest NVIDIA proprietary Linux graphics driver. While the Kepler cards now support GPU re-clocking, the results aren't quite ideal yet.

Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming

Back in 2012 with the NVIDIA 310 Linux driver series a threaded OpenGL optimization was added to the proprietary graphics driver. When this driver premiered we tested NVIDIA's Linux threaded OpenGL optimizations to mixed results. We're back now re-testing the OpenGL threaded optimizations to see if it makes any more of a difference now with modern Linux games and OpenGL workloads while using the latest 337.25 Linux driver.

Nouveau Re-Clocking Is Way Faster, Shows Much Progress For Open-Source NVIDIA

Earlier this week on Phoronix we covered the steps to trying out Nouveau re-clocking with Linux 3.16, assuming you're running a supported NVIDIA GPU that can currently be statically re-clocked using this reverse-engineered graphics driver. While the support is still experimental and isn't intended for end-users, here are some fresh benchmarks of the Nouveau driver DRM code for Linux 3.16 when re-clocked.

Open-Source Radeon Takes On AMD Catalyst In 2D Performance

Last weekend I published 2D performance benchmarks comparing Nouveau to NVIDIA's official driver. To no real surprise, the proprietary NVIDIA driver beat Nouveau in most micro-benchmarks when it comes to 2D (and separately, 3D) performance. With the open-source Radeon stack, however, it presents a much tougher fight against the proprietary Catalyst driver.

30-way Intel/AMD/NVIDIA Linux 2D Performance Comparison

A few days ago I began testing over 60 GPUs with the Intel/AMD/NVIDIA open-source Linux drivers. From that huge assortment of hardware I was able to deliver a plethora of Linux gaming and other OpenGL benchmarks from 50 of the graphics cards. I already followed-up with the performance-per-Watt and efficiency data for the wide assortment of graphics cards on the open-source drivers. As the last article looking at the open-source performance before switching over to the AMD Catalyst and NVIDIA proprietary Linux benchmarks, here are some 2D performance results from the Linux desktop.
