It's been a while since last running any video acceleration benchmarks at Phoronix so this week we're running a fresh set of VDPAU (Video Decode and Presentation API for Unix) benchmarks with NVIDIA's official driver plus for AMD Radeon hardware using the Radeon VDPAU state tracker support.
Besides the Nouveau driver performance being faster thanks to experimental re-clocking when using the Linux 3.16 kernel, there are also performance improvements to note with some generations of AMD graphics processors.
Back in 2012 with the NVIDIA 310 Linux driver series a threaded OpenGL optimization was added to the proprietary graphics driver. When this driver premiered we tested NVIDIA's Linux threaded OpenGL optimizations to mixed results. We're back now re-testing the OpenGL threaded optimizations to see if it makes any more of a difference now with modern Linux games and OpenGL workloads while using the latest 337.25 Linux driver.
Earlier this week on Phoronix we covered the steps to trying out Nouveau re-clocking with Linux 3.16, assuming you're running a supported NVIDIA GPU that can currently be statically re-clocked using this reverse-engineered graphics driver. While the support is still experimental and isn't intended for end-users, here are some fresh benchmarks of the Nouveau driver DRM code for Linux 3.16 when re-clocked.
Last weekend I published 2D performance benchmarks comparing Nouveau to NVIDIA's official driver. To no real surprise, the proprietary NVIDIA driver beat Nouveau in most micro-benchmarks when it comes to 2D (and separately, 3D) performance. With the open-source Radeon stack, however, it presents a much tougher fight against the proprietary Catalyst driver.
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.
