Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming

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.

Nouveau Re-Clocking Is Way Faster, Shows Much Progress For Open-Source NVIDIA

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.

Open-Source Radeon Takes On AMD Catalyst In 2D Performance

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.

30-way Intel/AMD/NVIDIA Linux 2D Performance Comparison

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.

Updated Intel Graphics Stack On Ubuntu 14.04 Has Some Slowdowns

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.

Catalyst On Ubuntu 14.04 Linux Competes Well With Windows 8.1

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.

AMD Radeon R9 290 On Ubuntu 14.04 With Catalyst Can Beat Windows 8.1

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.

Radeon: Mesa 10.1 vs. Mesa Git On Ubuntu 14.04

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.

Intel HD Graphics On Linux 3.15 Brings Few Changes

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.

Radeon DRM Graphics Benchmarks On Linux 3.15

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.

Testing NVIDIA Optimus / DRI PRIME On Ubuntu 14.04

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.

AMD Catalyst 14.4 On Linux With Radeon R3 APU Graphics

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.

AMD Athlon's R3 Graphics: RadeonSI Gallium3D vs. Catalyst

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.
