With Ubuntu 14.04 LTS there is improved support for multi-GPU laptops (commonly what's branded as NVIDIA Optimus configurations) where there is a discrete NVIDIA GPU used for high performance workloads to complement the low-power Intel integrated graphics. Ubuntu 14.04 LTS features better support for these Optimus / DRI PRIME configurations on both the open and closed-source graphics drivers. Here's the Ubuntu 14.04 multi-GPU experience along with some OpenGL benchmarks and power consumption numbers between the different configurations.
Tested yesterday at Phoronix was the AMD Catalyst 14.4 Linux performance where several newer, high-end graphics cards were tested from a Core i7 Haswell system. With that hardware, there was little in the way of OpenGL performance changes except for a couple of tests. Several Phoronix readers expressed interest in Catalyst 14.4 AMD AM1 APU tests in seeing if there are any improvements for the new APUs with Radeon R3 Graphics or performance improvements in general out of Catalyst 14.4 for reduced OpenGL overhead on lower-end processors. In this article are Catalyst 14.3 vs. 14.4 Ubuntu Linux benchmarks with an AMD Athlon 5350.
On Monday AMD made publicly available the release candidate to the Catalyst 14.4 Linux driver that brings full OpenGL 4.4 support. Some Phoronix readers have reported performance changes with this new driver update, so I have done some comparison tests on several AMD Radeon graphics drivers to see how the performance compares with Catalyst 14.4 on Ubuntu Linux.
For those wondering how much video memory you should allocate from your system RAM for the Radeon R3 Graphics with the new AM1 APUs, we have up some new Linux OpenGL benchmarks of the AMD Athlon 5350 performance with varying amounts of video memory available.
For those curious how AMD's AM1 APUs are running with OpenCL workloads given the company's focus on HSA, here's a wide-range of OpenCL benchmarks from the four Athlon and Sempron AM1 APUs currently on the market while running Ubuntu 14.04 LTS.
For the past week now we have been extensively benchmarking AMD's new AM1 APUs with all the current models available to the public: the Sempron 2650 / 3850 and Athlon 5150 / 5350. All of our testing up to this point has been using an updated Linux kernel and Mesa for the open-source Linux graphics driver experience with these APU Radeon R3 Graphics. Today, we're looking at the performance of the open-source RadeonSI Gallium3D driver in multiple configurations compared to the proprietary Catalyst Linux driver.
NVIDIA released their first 337 Linux driver beta earlier this week and it finally brings GPU overclocking support for the GeForce 400 "Fermi" series and newer, up through the latest-generation Maxwell graphics hardware.
Yesterday I delivered the first Linux benchmarks of the AMD Athlon 5350 with Radeon R3 Graphics. Benchmarks of the socketed Kabini APU are ongoing at Phoronix in a variety of different software and hardware configurations. The tests that have just wrapped up today are checking out the performance when upgrading the Linux kernel and Mesa compared to what's shipped by default in Ubuntu 14.04 LTS.
For those curious about the current performance level of the LLVMpipe software-renderer OpenGL driver for Mesa's Gallium3D in Ubuntu 14.04 LTS, here's some new benchmarks.
Last week we covered a 13-way Radeon GPU comparison on Ubuntu 14.04 and we also looked at the state of Nouveau on Ubuntu 14.04 with many NVIDIA GeForce graphics cards. In concluding our latest round of open-source graphics driver tests from the upcoming Ubuntu 14.04 LTS "Trusty Tahr", here's a 20-way graphics processor comparison using AMD Radeon, NVIDIA GeForce, and Intel HD Graphics hardware.
In my testing of Ubuntu 14.04 LTS with the Linux 3.13 kernel and Mesa 10.1 for the open-source graphics driver stack provided by Nouveau for NVIDIA GeForce graphics hardware, only the Fermi and Kepler GPUs are running reliably. While these newer NVIDIA GPUs are running stable with Ubuntu 14.04, the performance is still a wreck due to lack of reclocking.
To complement last week's Radeon Windows Catalyst vs. Linux Gallium3D vs. Linux Catalyst OpenGL performance comparison on Ubuntu 14.04 LTS, here's benchmarks of thirteen different AMD Radeon graphics cards on the near-final state of Ubuntu 14.04 LTS "Trusty Tahr" in its current development form.
Our latest Windows vs. Linux benchmarks on Ubuntu 14.04 LTS are of three different AMD Radeon graphics cards from three different generations as we test the performance of Microsoft Windows 8.1 against Ubuntu 14.04 LTS, when using both the AMD Catalyst proprietary driver and the open-source R600/RadeonSI Gallium3D drivers.
This week I was out at the Game Developer's Conference not with a focus on games but to learn about some changes they AMD currently pursuing for their Linux driver model. If this new Linux driver model goes through, the Catalyst Linux driver will be more open, but it's not without some risk. Read more in this Phoronix exclusive story.
For current and potential owners of NVIDIA GeForce 700 series graphics cards that are curious about the graphics driver situation on Linux, under Ubuntu 14.04 LTS with the latest open and closed-source NVIDIA drivers with the latest "Kepler" and "Maxwell" graphics cards. Here's what you need to know now if trying to use the open-source Nouveau driver with these very latest NVIDIA graphics processors.
After earlier this week sharing 2D benchmarks of the Intel, Radeon, and Nouveau drivers using the different X.Org acceleration architectures, the benchmarks in this article are looking at the always-interesting OpenGL performance for the same diverse selection of hardware when using the latest development code via the Linux 3.14 kernel and Mesa 10.2-devel.
While 3D/OpenGL is our primary focus of performance tests when it comes to graphics cards on Linux, it's always interesting to go back and check on the 2D performance as it's still important for the Linux desktop experience. The 2D performance is becoming interesting right now as well due to Intel's driver defaulting to SNA and GLAMOR acceleration being tried by some drivers for faster 2D over OpenGL. In this article we have some fresh 2D benchmarks of Intel, NVIDIA, and AMD graphics hardware running an updated open-source GPU driver stack on Ubuntu 14.04 LTS.
With GLAMOR generating a lot of interest lately due to AMD's RadeonSI Gallium3D driver depending upon it and Intel driving lots of improvements into it now that it's been merged into the X.Org Server, here's some new benchmarks of Intel Haswell HD Graphics 2D performance of the latest Intel xf86-video-intel 3.0 pre-release on Ubuntu 14.04 LTS comparing the GLAMOR, UXA, and SNA acceleration architectures.
Mesa 10.1 was released this morning as the latest three-month update to this 3D library and graphics driver stack used throughout the Linux desktop ecosystem. With Mesa 10.1 there are tons of improvements, while one of the big highlights is OpenGL 3.3 support for the open-source Radeon and Nouveau drivers.
Yesterday on Phoronix I published results showing the Radeon Gallium3D performance getting close to Catalyst for the Radeon HD 5000 series and newer GPUs that are supported by the mainline Catalyst driver. On the open-source side the hardware is supported by the R600 and RadeonSI (for the GCN hardware) Gallium3D drivers. Yesterday's results showed that on Ubuntu 14.04 for many OpenGL workloads the R600/RadeonSI Gallium3D drivers were now ~80% the speed of the proprietary Catalyst driver in many instances. While this is a great feat, how does it stand for older generations of AMD Radeon hardware? In this article are Radeon HD 4870 benchmarks looking at the performance of the open-source AMD Linux driver over three years of Ubuntu Linux releases and compared to the legacy Catalyst driver from 2011.
With the open-source graphics driver stack found in the forthcoming release of Ubuntu 14.04 LTS (Mesa 10.1 + Linux 3.13), the performance of the community-developed Radeon Gallium3D driver is now close to that of the official AMD Catalyst driver for recent generations of Radeon graphics cards. In several OpenGL tests the "RadeonSI" driver can even run 80% the speed of AMD's official Catalyst Linux driver.
For anyone currently experiencing a slowdown of their Radeon Gallium3D open-source driver stack or are interested in helping out track down a new performance issue, it appears the Linux 3.14 + Mesa 10.2 configuration is regressing on Ubuntu 14.04 LTS in place of Linux 3.13 + Mesa 10.1.
With the imminent release of Mesa 10.1 and Ubuntu 14.04 LTS landing this updated open-source 3D graphics stack at the last minute, here are some benchmarks of this preliminary open-source GPU driver stack of Ubuntu 14.04 with Mesa 10.1 and the Linux 3.13 kernel. With Mesa 10.1 there is now also Unigine Heaven & Valley benchmarks that are now compatible with the Radeon Gallium3D drivers.
In finding it interesting that the Radeon HD 8210 Gallium3D performance can outperform Catalyst from an AMD E1-2100 "Kabini" low-end APU, which was tested on an ECS KBN-I Kabini system that can be found for just over $30 USD when on sale, it's time for some more Linux benchmarks. The latest tests from this low-end but fascinating platform are benchmarking a variety of PCI-E graphics cards on this AMD Kabini platform using the open-source Radeon and Nouveau graphics drivers on Ubuntu 14.04.
For those curious how AMD's Catalyst Linux performance is doing as we get 2014 underway with the first Catalyst 14.1 beta, here are benchmarks from nine different AMD Radeon graphics cards under Ubuntu Linux and running this latest publicly available driver when looking at both the OpenGL graphics and OpenCL compute performance.
Some of our final Linux benchmarks at Phoronix to end out January are of looking at the Mesa 10.0 vs. 10.1-devel performance for Intel HD Graphics 4600 on a Core i5 processor while running Ubuntu 14.04. Is there much in store for Haswell with this upcoming three-month update to Mesa?
Earlier this month I shared some basic OpenGL benchmarks between AMD's Kaveri APU on the Catalyst driver and the open-source RadeonSI Gallium3D driver. Now that more time has passed I'm back with another round of Linux graphics driver testing on the AMD A10-7850K, this time looking at the impact when forcing Dynamic Power Management and toggling color tiling for maximum performance.
Nouveau, the reverse-engineered open-source NVIDIA Linux graphics driver that's been in development now for the better part of a decade, is working brilliantly for some NVIDIA GeForce graphics cards while for other NVIDIA GPUs the experience is a sloppy mess. Using the Linux 3.13 kernel and Mesa 10.1-devel Gallium3D driver code installed on top of Ubuntu 13.10, here's what the experience is like when trying a number of GeForce graphics cards with this latest open-source driver code.
Yesterday I ran the latest RadeonSI Gallium3D vs. Catalyst AMD Linux driver comparison, effectively another round of open-source vs. closed-source GPU driver testing. In yesterday's article it was found the RadeonSI performance is improving a lot but the AMD Catalyst Linux driver remains much faster. In this article are benchmarks of the older "R600" Radeon Gallium3D driver compared to the Catalyst driver with graphics cards from the Radeon HD 6000 series and older where the open-source R600g driver provides support and in a more mature state.
While NVIDIA's binary driver is much faster and better than AMD's Catalyst, on the open-source driver side is where AMD has been shining. While their RadeonSI Gallium3D driver for Radeon HD 7000 series GPUs and newer is not nearly as well off as their pre-HD 7000 series (R600g) Gallium3D driver, they are making progress. In this article are benchmarks showing the "out of the box" performance on Ubuntu 13.10 with the modern open-source driver, benchmarks with the latest kernel and Mesa and LLVM, and then the AMD Catalyst driver. A range of modern Radeon HD 7000 and R9 graphics processors were used for this open-source versus closed-source driver testing.
