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.
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.
Five years after the OpenGL 4.0 specification was introduced, the open-source Mesa 3D project has finally moved on to supporting the necessary extensions, the open-source NVIDIA (Nouveau) driver even exposes OpenGL 4.1 support this morning, and OpenGL 4.2 patches are pending.
With the big Catalyst 15.7 Linux driver update released last week and the continued evolution of the open-source AMD Linux driver in the Linux kernel and Mesa Gallium3D, here are fresh benchmarks of six different AMD Radeon graphics cards when being tested on both the open and closed-source drivers to represent the AMD Linux gaming experience this summer.
After earlier this week looking at whether the open-source NVIDIA driver is fast enough for Steam Linux gaming, here are some benchmark results that compare the performance of the latest Nouveau Gallium3D driver code against the latest NVIDIA binary Linux graphics driver.
As part of the other Linux graphics tests running this week, here are the results of eight different graphics cards -- from both NVIDIA and AMD -- being tested on the latest open-source Linux graphics drivers under a variety of OpenGL Linux games. The software stack making up this round of testing was the Linux 4.1.1 kernel and Mesa 10.7-devel atop Ubuntu 15.04.
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.
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.
As another large, historical test in celebrating Phoronix's 11th birthday this month, here are some benchmarks looking at the Intel Sandy Bridge HD Graphics 2500 performance on Ubuntu Linux over the past three years. Every Ubuntu Linux release from 12.10 to 15.04 was tested, plus the latest Linux kernel and Mesa Git code.
In celebrating 11 years since starting Phoronix to cover the Linux hardware scene, here's some fresh benchmarks of the open-source Intel / AMD / NVIDIA Linux graphics drivers. Various GPUs were tested atop Ubuntu when moving to Git with the Linux 4.1 kernel, Mesa 10.7-devel, and LLVM 3.7 SVN.
With Mesa 10.6 due to be released in early June, our usual performance comparisons of this new Mesa 3D version will come. To get our latest round of Mesa open-source graphics driver benchmarking kicked off, here are benchmarks of Intel's Iris Graphics when comparing Mesa 10.5 and 10.6 Git atop Ubuntu 15.04.
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.
Yesterday I posted some benchmark results showing the AMD Radeon R9 290 graphics card on Ubuntu 15.04 and comparing the Catalyst driver to the open-source RadeonSI Gallium3D driver as found on this new Linux distribution release. The previous article focused on the OpenGL performance while today's article is looking squarely at the 2D performance.
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.
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.
Before ending out March, here's some new OpenGL Linux benchmarks comparing the closed-source Catalyst 15.3 Beta driver against the Linux 4.0 development kernel with Mesa 10.6 Git for the freshest open-source graphics driver code.
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.
With Ubuntu 15.04 now shipping X.Org Server 1.17, I've run some 2D performance tests comparing the performance of this newest Ubuntu version when using the open-source Radeon graphics driver -- both with the EXA and GLAMOR acceleration methods -- compared to the new Catalyst Linux driver beta.
With the Linux 4.0 kernel getting into shape here are some early benchmarks of three AMD Radeon graphics cards when comparing the Linux 4.0 Git performance to that of the Linux 3.19 stable kernel.
It's been several weeks since last publishing any Mesa/LLVM Git benchmarks with AMD Radeon graphics cards so for this weekend article are some fresh OpenGL graphics performance tests when running with Mesa 10.6-devel Git and LLVM 3.7 SVN atop the stable Linux 3.19 kernel.
Today is a very exciting day for those into open standard graphics and compute APIs! While driver implementations aren't expected until later in 2015, the next-generation OpenGL standard is being announced as the Vulkan API, the provisional specification to OpenCL 2.1 is being released, and SPIR-V is set to make its debut as the IR for both Vulkan and OpenCL 2.1.
Following yesterday's NVIDIA GeForce GTX 960 launch, here's an 11-way comparison looking at all of NVIDIA's Maxwell GPUs as well as many Kepler and Fermi GeForce graphics cards under Linux. Beyond the raw OpenGL performance, the thermal and power efficiency data is also available for the tested range of GeForce 900/700/600/500/400 series graphics cards.
This week on Phoronix were many Linux graphics tests from Unreal Engine 4 to Metro Redux with twenty-two AMD Radeon and NVIDIA GeForce graphics cards. Yesterday was also a 22-way GPU Linux OpenCL comparison. For your weekend viewing pleasure are now 2D desktop benchmarks from all of these GeForce and Radeon graphics cards atop Ubuntu Linux.
As it's been a while since last running any large OpenCL benchmark comparisons, here's some updated figures for a wide-range of AMD and NVIDIA graphics cards. In total twenty-two graphics cards were tested with the latest AMD and NVIDIA drivers to see the current OpenCL GPU performance.
After last week delivering initial open-source Radeon DRM driver tests on Linux 3.19, here's similar treatment in testing out the new Linux 3.19 kernel with the Nouveau DRM driver for open-source NVIDIA graphics.
With the Linux 3.19 kernel stabilizing nicely, here's a first look at the open-source AMD Radeon graphics performance using this new kernel that will be officially released in the weeks ahead. The Linux 3.18 kernel was compared to the latest Git code of Linux 3.19 for several different AMD Radeon HD series and Rx 200 series graphics cards.
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.
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.
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.
Complementing yesterday's Radeon Gallium3D vs. Catalyst Linux benchmarks that compared AMD's open and closed-source Linux graphics drivers using the latest code at the end of 2014, here's similar benchmarks done in comparing the open-source Nouveau driver against the closed-source NVIDIA Linux graphics driver when testing several GeForce GPUs.
