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.

AMD Radeon R9 290 OpenGL On Ubuntu 15.04: Catalyst vs. RadeonSI Gallium3D

While I've posted some new AMD OpenGL benchmarks on Ubuntu 15.04 since last week's release of the Vivid Vervet, the Radeon R9 290 wasn't tested since at that time this Hawaii graphics card was busy on other Phoronix test systems. However, due to the interest level in seeing some fresh Ubuntu 15.04 numbers for the Radeon R9 290 series, here's some numbers.

Ubuntu 15.04 Offers Faster OpenGL For AMD Radeon GPUs On Open-Source

Intel Haswell Linux users are greeted by relatively modest performance changes with Ubuntu 15.04 while those using AMD Radeon graphics cards on the open-source R600 and RadeonSI Gallium3D drivers have much more to look forward to when upgrading to this week's release of Ubuntu 15.04. Here's some Ubuntu 14.10 vs. Ubuntu 15.04 OpenGL benchmarks for a range of AMD Radeon graphics cards.

OpenGL Threaded Optimizations Responsible For NVIDIA's Faster Performance?

With the recent BioShock Infinite Linux benchmark results and the big Metro Redux graphics card comparison on Linux, a fair number of Linux gamers have been bringing it up in the forums with their hypothesis that NVIDIA's Linux gaming performance wins is due to their driver supporting OpenGL threaded optimizations. Well, that's not always the case, as shown in this article with a __GL_THREADED_OPTIMIZATIONS comparison in many Linux games with different GeForce hardware.

NVIDIA GeForce GTX 970/980: Windows vs. Ubuntu Linux Performance

Earlier this week I posted some benchmarks showing NVIDIA's Linux Driver Continues Running Strong Against The Windows Driver that also included the open-source Nouveau driver results in the mix too. However, due to using the Nouveau driver, the newest GeForce GTX 970/980 graphics cards were left out of testing as the open-source driver doesn't yet fully support these newer Maxwell GPUs. In this article though we're going back to compare the Windows vs. Linux performance of these two high-end NVIDIA GPUs at a UHD 4K resolution too.

NVIDIA Linux Driver Continues Running Strong Against The GeForce Windows Driver

With last week having delivered fresh benchmarks of AMD's Catalyst Linux vs. Windows drivers (and before that an updated Intel Linux vs. Windows OpenGL comparison to end out 2014), here's some updated NVIDIA Linux vs. Windows benchmarks to compare the GeForce graphics drivers at the end of 2014. Three different graphics cards were used in benchmarking the latest NVIDIA Linux vs. Windows performance with the proprietary graphics drivers followed by also having the latest open-source NVIDIA/Nouveau driver results.

Intel Haswell Linux OpenGL Driver Catching Up To The Windows Driver

Past Intel Windows vs. Linux graphics driver benchmarks have shown that for Haswell the OpenGL performance on Linux generally comes up short of the proprietary Windows driver. Fortunately, the Intel open-source Linux driver improved a lot this year and is now more competitive to the Windows driver.
