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.

How AMDGPU With PowerPlay Compares To Other Radeon GPUs

Last weekend I ran benchmarks looking at the performance of the AMDGPU DRM driver with the new PowerPlay patches for providing proper power management support for Tonga and Fiji graphics cards. In today's article is a larger comparison when running this latest Radeon and AMDGPU DRM driver code to see how these newer AMD GPUs compare to existing, well-supported Radeon graphics cards.

AMD Tonga & Fiji Open-Source Performance Boosted By PowerPlay Patches

Yesterday AMD finally posted power management support for the AMDGPU DRM kernel driver when it comes to supported discrete graphics cards like Tonga and Fiji. I've been testing these PowerPlay Linux patches since yesterday to great success. In this article are results from a Radeon R9 285 and Radeon R9 Fury when testing these kernel patches along with the latest Mesa 11.1-devel Git drivers.

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.

The Performance Gains Made By AMD's RadeonSI Open-Source Driver In Two Years

Earlier this week we took a look at the AMD Radeon R600 Gallium3D performance over two years by benchmarking every Ubuntu Linux release since early 2013 with a Radeon HD 6000 series graphics card. Today up for your viewing pleasure are the results from a similar test but using a Radeon Rx 200 series graphics card with the newer RadeonSI Gallium3D driver for open-source AMD GCN GPUs.

AMD Radeon R600 Gallium3D Performance Over The Past Two Years

Today's Linux benchmarking is looking at the performance of the open-source Radeon R600g Gallium3D driver for pre-GCN GPUs over the past two years. A Radeon HD 6870 was used while testing all of the Ubuntu Linux releases going back to Ubuntu 13.04, plus the latest Git code as well.

Running The AMD Radeon R9 Fury With AMD's New Open-Source Linux Driver

Now that Linux 4.2 is set to be released today, out on the horizon we have to look forward to Linux 4.3 kernel. Set to be merged into Linux 4.3 will be in the initial open-source AMD driver code for supporting the Radeon R9 Fury graphics cards. This open-source Fury support is the focus of our testing today with it being the first time powering up this Fiji GPU outside of Catalyst.

Mesa 11.1-dev Tests With The Reverted RadeonSI Performance

This week I posted some AMD RadeonSI/R600g tests on Mesa 11.0 with DRM-Next along with a Intel Skylake vs. Radeon comparison using this new version of Mesa that will be officially released next month. Of course, following those tests, the requests turned to testing Mesa 11.1-devel rather than the Mesa 11.0 Git code.

Open-Source Linux Driver Comparison: Skylake HD Graphics vs. Radeon Gallium3D

With my Skylake HD Graphics 530 Linux tests earlier this month from the new Intel Core i5 6600K processor, I compared the performance to several Haswell/Broadwell CPUs as well as AMD APUs. In this article I'm providing some fresh benchmark results of Intel's "Gen9" graphics compared to discrete AMD Radeon GPUs tested on the same Skylake system. All tests were done with Mesa 11.0 code and the DRM-Next code for Linux 4.3.

Where AMD's Catalyst Driver Does The Best On Linux

Earlier this week I finished up a 15-way AMD/NVIDIA graphics card comparison on Linux with the very latest proprietary Linux drivers. That earlier article focused on the OpenGL performance and simply put the Catalyst performance on the tested Radeon hardware was abysmal compared to NVIDIA's Linux driver performance. However, there is one area where the Catalyst Linux driver really excels at performance and routinely beats out the green competition.
