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.

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.

AMD RadeonSI & R600g Gallium3D Tests On Mesa 11.0 + DRM-Next

As some new Mesa 11.0 benchmarks to publish is looking at the performance of several Radeon GPUs on the R600g and RadeonSI Gallium3D drivers as tested out-of-the-box on Ubuntu 15.04 with the Linux 3.19 kernel and Mesa 10.5.2, then compared to the DRM-Next code for Linux 4.3 plus Mesa 11.0-rc1.

The New AMD GPU Open-Source Driver On Linux 4.2 Works, But Still A Lot Of Work Ahead

With the Linux 4.2 kernel settling down nicely and AMD developers having already sent in a few round of fixes for their new AMDGPU kernel DRM driver, I've started testing out this new kernel driver -- plus the new xf86-video-amdgpu DDX and the associated new Mesa/LibDRM code -- that is providing the open-source accelerated graphics support for Tonga and all new/future GPUs like Carrizo and Fiji.

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.

AMD A10-7870K Godavari: RadeonSI Gallium3D vs. Catalyst Linux Drivers

Last week I started posting AMD A10-7870K Linux benchmarks for this "Godavari" APU that's effectively a Kaveri Refresh and slightly faster for its four CPU cores and Radeon R7 Graphics over the former high-end Kaveri, the A10-7850K. In today's articles are some benchmarks of the Radeon R7 Graphics on the A10-7870K when running Ubuntu and testing the open-source RadeonSI Gallium3D driver against Catalyst on Linux.

Catalyst 15.5 For Linux Brings Some Performance Improvements

Earlier this month Catalyst 15.5 was released for Linux as the first official Linux graphics driver update since last December when Catalyst 14.12 was released (sans the special fglrx driver packaged by Canonical for Ubuntu 15.04). As discussed by users in our forums and elsewhere, Catalyst 15.5 does offer better performance for certain OpenGL workloads compared to the earlier driver, but the gains aren't universal.

GeForce GTX 750 Series: Nouveau vs. NVIDIA Linux Driver Performance

With the forthcoming Linux 4.1 kernel there is finally out-of-the-box acceleration for the NVIDIA GeForce GTX 750 series on the Nouveau driver. With the Nouveau DRM/KMS driver able to self-generate the needed firmware/microcode to enable acceleration, it's quite easy to get running. However, the performance leaves a lot to be desired.
