Catalyst vs. AMDGPU vs. Radeon DRM On A R9 290: Experimental AMDGPU Can Be Faster

While the AMDGPU Linux kernel driver right now exposes support for AMD GCN 1.2 GPUs and newer, like Carrizo, Fiji, and Tonga, it is possible to get GCN 1.1 Sea Islands hardware working with this driver if jumping through a few hoops. In this article are some tests of a Radeon R9 290 "Hawaii" when using the proprietary Catalyst driver, Radeon DRM driver as is the default for this card on open-source, and then using the experimental AMDGPU DRM open-source support.

Linux 4.5 AMDGPU/Radeon vs. Catalyst OpenGL Performance

With the first test release out this week for the Linux 4.5 kernel I have carried out some fresh benchmarks on different AMD Radeon graphics cards for comparing the very latest open-source driver performance against that of the proprietary AMD Linux driver. Here are how the competing AMD OpenGL Linux stacks are comparing to one another for starting off 2016.

How Haswell OpenGL Performance On Linux Changed In 2015

Yesterday I published our usual end-of-year results showing how AMD's open-source driver evolved in 2015 with regard to its OpenGL performance. For your viewing pleasure today are similar results but on the Intel Haswell side looking at how the open-source Intel Linux driver performance changed since the end of 2014.

New AMD GPU Performance To Be Boosted By Linux 4.5; How It Compares To The Binary Blob

Last week I posted some AMD proprietary vs. open-source AMD Linux driver benchmarks using the very latest code. Left out of that earlier comparison was the R9 Fury series with Fiji GPU as well as newer graphics cards using the Tonga GPU. These graphics cards are supported by the AMDGPU DRM driver rather than the long-standing Radeon DRM driver. As I've been mentioning a lot this week, Linux 4.5 will bring the PowerPlay power management / re-clocking support to AMDGPU. In this article are showing benchmarks of the Fiji and Tonga GPUs under Linux 4.4 and Linux 4.5 DRM-Next along with the Catalyst 15.9 driver as shipped by Ubuntu 15.10.

NVIDIA vs. Nouveau Linux Driver Performance With Extra Re-Clocking Patches

Last week I posted benchmarks of the AMD proprietary vs. open-source Radeon R600/RadeonSI Gallium3D drivers of various graphics cards on the newest open-source code. Today I'm doing a similar treatment on the NVIDIA GeForce side with seeing how their proprietary driver compares to the latest open-source Nouveau code.

Proprietary vs. Linux Git, Mesa 11.2-devel, DRI3 For R600g/RadeonSI

Following this week's OpenGL 4.1 R600g benchmarking with that newly-enabled OpenGL 4 support, I set out to run a larger hardware comparison on both the R600g and RadeonSI drivers as part of our year-end 2015 Linux benchmarking. In this article are tests of seven AMD Radeon graphics cards tested on the proprietary driver compared to the latest open-source driver stack -- with extra steps of enabling DRI3 rendering and also using the latest AMDGPU PowerPlay code.

With R600g Now Supporting OpenGL 4.1, See How The Open-Source Performance Compares To AMD Catalyst

There are two reasons for doing some end-of-the-year Radeon R600 Gallium3D driver testing with pre-GCN graphics cards. First, since the pre-GCN (HD 6000 series and older) support is being dropped by the new Radeon Software driver. Secondly, the R600g open-source driver finally supports OpenGL 4.1 for select GPUs. In this article is a look at the AMD Catalyst Linux driver with the last official release for HD 6000 series hardware compared to the very latest open-source Radeon graphics stack on Ubuntu Linux with a variety of interesting OpenGL Linux game tests.

Radeon DRM Linux 4.4 + Mesa 11.1 + DRI3 vs. AMD's Proprietary Driver

On Friday I posted benchmarks showing Nouveau's re-clocked performance relative to NVIDIA's proprietary driver for showing the performance potential of NVIDIA's GeForce GTX 600/700 series with the performance state code there beginning to work. That article was followed by AMDGPU driver tests on Linux 4.4 against Catalyst for the newest AMD GPU tech that uses this newer Direct Rendering Manager driver. The third test now is comparing the Radeon DRM performance on Linux 4.4 against AMD's binary blob when using older AMD GCN GPUs as well as a Northern Islands GPU for reference.

AMDGPU With PowerPlay Compared To AMD's Catalyst Linux Driver

With earlier today showing new OpenGL performance numbers for how the Nouveau driver with working re-clocking compared to NVIDIA's proprietary driver, here are some benchmarks to show how the AMDGPU kernel DRM driver with PowerPlay patches compare to AMD's Catalyst driver for the R9 285 (Tonga) and R9 Fury (Fiji) graphics cards.

How Nouveau Compares To NVIDIA's Linux Driver When Kepler Re-Clocking Works

With the upcoming Linux 4.4 kernel, the Kepler re-clocking is in much better shape and for select GeForce GTX 600/700 series cards now allows the open-source driver to run them at their fully-rated clock frequencies. Here's some tests showing how Nouveau now compares to NVIDIA's proprietary Linux driver in such a comparison.

AMD Radeon Software Crimson Edition Is A Letdown On Linux

While leaked slides indicate AMD was planning better gaming on Linux for Crimson, in the end they really didn't deliver. Even for their mentioned games, when testing various Linux OpenGL games on three different systems the performance was largely unchanged.

DRI2 vs. DRI3 Radeon Linux OpenGL Performance

Following the recent Phoronix article about the state of DRI3 for X.Org drivers, many in the forums began discussing DRI3. While the Intel and Radeon X.Org drivers don't yet enable Direct Rendering Infrastructure 3 by default, I decided to run some fresh OpenGL benchmarks with a few Radeon graphics cards to compare the performance of DRI2 and DRI3.
