With the Linux 3.16 kernel comes the ability to re-clock select NVIDIA GeForce GPUs when using the open-source, reverse-engineered Nouveau driver. Here's my first impressions with trying out this option to maximize the performance of NVIDIA graphics cards on open-source drivers.
With the APITest OpenGL 4.x tests developed by John McDonald at NVIDIA who is now working for Valve on their Linux-related endeavors, the AMD Catalyst driver gets absolutely annihilated for these GL4 micro-benchmarks.
After last weekend delivering 30-way Intel/AMD/NVIDIA 2D Linux benchmarks this weekend I have some results comparing the GeForce GPU performance for 2D operations between the open-source Nouveau driver and the closed-source proprietary NVIDIA Linux driver.
The Linux graphics benchmarks we have to publish today at Phoronix are some tests of the Intel "ILO" Gallium3D driver that is independently developed by LunarG as an unofficial alternative to the classic Intel Mesa DRI driver that's officially supported by the Intel Open-Source Technology Center.
For those of you with NVIDIA graphics cards prior to the GeForce 400 "Fermi" series, NVIDIA is soon eliminating the support from their mainline proprietary Linux graphics driver.
A few days ago I began testing over 60 GPUs with the Intel/AMD/NVIDIA open-source Linux drivers. From that huge assortment of hardware I was able to deliver a plethora of Linux gaming and other OpenGL benchmarks from 50 of the graphics cards. I already followed-up with the performance-per-Watt and efficiency data for the wide assortment of graphics cards on the open-source drivers. As the last article looking at the open-source performance before switching over to the AMD Catalyst and NVIDIA proprietary Linux benchmarks, here are some 2D performance results from the Linux desktop.
This week there's already been a high-end OpenGL comparison using the latest proprietary drivers with newer AMD Radeon and NVIDIA GeForce graphics cards. Those OpenGL results were followed by a 2D NVIDIA/AMD Linux performance comparison and now to end out the week are some OpenCL compute benchmarks.
Yesterday on Phoronix we had benchmarks of high-end NVIDIA and AMD GPUs when looking at the Linux OpenGL performance on the proprietary drivers. For those more concerned about the 2D performance of the modern GeForce and Radeon graphics cards, here's some benchmarks for you.
For those curious about the impact of running Intel "Haswell" HD Graphics 4600 on Ubuntu 14.04 LTS and then pulling in the latest Mesa 10.3-devel code followed by the Linux 3.15 kernel, it's not entirely a happy story if you are looking to maximize your Intel Linux graphics performance capabilities.
After this week having carried out benchmarks showing Intel's Windows 8.1 OpenGL driver is outperforming their open-source Linux driver but NVIDIA's driver on Ubuntu Linux is commonly faster than Windows 8.1, the time has come to benchmark several different AMD Radeon graphics cards under Ubuntu 14.04 LTS and Windows 8.1 Pro x64 with all available updates and each OS using the latest Catalyst 14.4 driver.
The latest Linux graphics testing under the microscope at Phoronix is comparing the Ubuntu 14.04 LTS vs. Windows 8.1 performance with all available updates. Results from Intel, NVIDIA, and AMD hardware is coming up next week while today is a bit of a preview of the AMD numbers when using a Radeon R9 290 "Hawaii" graphics card. While the open-source AMD Hawaii support remains broken, with the Catalyst 14.4 driver on each operating system, the Linux Catalyst driver with the R9 290 graphics card can outperform Windows 8.1 Pro with some OpenGL games and benchmarks.
Up for sharing today are our benchmarks comparing the very latest open-source Nouveau graphics driver code (Linux 3.15 + Mesa 10.3-devel) against the proprietary NVIDIA Linux graphics driver to see how the two NVIDIA Linux drivers compare.
After earlier this week doing an Intel vs. Radeon vs. Nouveau comparison using the very latest open-source Linux graphics driver code in the form of Mesa 10.3-devel and the Linux 3.15 kernel, here's benchmark results comparing the updated open-source AMD Radeon performance on Ubuntu 14.04 LTS against the Catalyst 14.4 Linux graphics driver.
The latest Linux graphics we have to benchmark at Phoronix are from a spectrum of Intel HD Graphics, AMD Radeon, and NVIDIA GeForce graphics when testing the latest open-source GPU drivers found with the in-development Linux 3.15 kernel and Mesa 10.3-devel.
With Mesa 10.2 just having been branched for its release in the weeks ahead, at Phoronix we have carried out some tests of four different graphics cards when using Mesa 10.1.0 as shipped by Ubuntu 14.04 LTS and then using the Oibaf PPA to upgrade to the latest Mesa 10.3-devel snapshot, which is still close to the state that Mesa 10.2 will be shipping.
Now that we have run the Nouveau open-source NVIDIA tests on the Linux 3.15 kernel and discovered there were no real performance changes for this latest Linux kernel, after finding some Radeon regressions in Linux 3.15, now our attention is on Intel and their Haswell-based HD Graphics. Fortunately, the Intel numbers are slightly more interesting than the Nouveau data.
Following this week's Radeon DRM benchmarks on Linux 3.15, here are benchmarks of the Nouveau open-source NVIDIA Linux graphics driver when using the 3.15 Git kernel compared to stable Linux 3.14.
Our latest focus in benchmarking the Linux 3.15 kernel is the Radeon DRM kernel graphics driver. There's been some reports of small performance changes with this newest kernel currently under development, in part due to some video memory optimizations that landed this cycle. In this article are benchmarks of four AMD Radeon graphics cards when running Linux 3.14 and 3.15 Git.
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.
