The NVIDIA GTX 900 Series Performance On The Open-Source Nouveau Driver

With the in-development Linux 4.6 kernel there is the long-awaited NVIDIA GeForce GTX 900 series accelerated support atop the open-source Nouveau driver. While it requires using NVIDIA's signed binary blobs for the firmware, the support is now working. Here are some benchmarks on several different GTX 900 Maxwell graphics cards comparing the open-source driver performance to what's offered by NVIDIA's proprietary Linux driver.

AMD GPU-PRO vs. NVIDIA Linux OpenCL Compute Performance

Following this week's AMD vs. NVIDIA Linux OpenGL and Vulkan benchmarks, you may be wondering about the performance of OpenCL GPGPU performance particularly around AMD's new hybrid Linux driver stack. So for your viewing pleasure today are some OpenCL benchmarks on AMD Radeon and NVIDIA GeForce hardware using the newest drivers.

AMD vs. NVIDIA Vulkan & OpenGL Linux Performance With The New Drivers

Thanks to AMD having released their new GPU-PRO "hybrid" Linux driver a few days ago, there is now Vulkan API support for Radeon GPU owners on Linux. This new AMD Linux driver holds much potential and the closed-source bits are now limited to user-space, among other benefits covered in dozens of Phoronix articles over recent months. With having this new driver in hand plus NVIDIA promoting their Vulkan support to the 364 Linux driver series, it's a great time for some benchmarking. Here are OpenGL and Vulkan atop Ubuntu 16.04 Linux for both AMD Radeon and NVIDIA GeForce graphics cards.

AMD GPU-PRO Hybrid Linux OpenGL Performance vs. RadeonSI Gallium3D

While still working on some AMD vs. NVIDIA Vulkan Linux driver benchmarks using AMD's new hybrid driver with Vulkan support, for your viewing pleasure this morning are some benchmarks comparing the new AMD GPU-PRO driver with its binary OpenGL driver against the pure open-source driver stack with the Ubuntu 16.04 AMDGPU driver and RadeonSI Gallium3D from Mesa 11.2 + LLVM 3.8.

NVIDIA GeForce vs. Radeon/AMDGPU OpenGL Performance On Ubuntu 16.04

This week we showed how the new AMDGPU driver stack is performing on Ubuntu 16.04 and that the recent generations of Radeon graphics cards are commonly seeing 80~90% the performance of Catalyst. However, it's important to keep in mind that aside from Catalyst being more buggy than the proprietary NVIDIA driver, the NVIDIA binary driver also tends to be more performant. So for putting the Ubuntu 16.04 open-source Radeon numbers into perspective, here are results putting them against the GeForce Kepler and Maxwell graphics cards.

Tonga AMDGPU Performance On Ubuntu 16.04 Has 80~90%+ Performance Of Catalyst

Earlier this week was the How Ubuntu 16.04 Is Performing With AMDGPU/Radeon Graphics Compared To Ubuntu 14.04 With FGLRX, which showed off some interesting open-source Radeon Linux driver results but the Radeon R9 285 "Tonga" graphics card at the time couldn't be tested on Ubuntu 16.04's kernel due to a regression. That issue is fortunately now resolved in the latest Xenial Xerus kernel so here are those numbers.

DRI2 vs. DRI3 Benchmarks With Intel Skylake HD Graphics 530

While DRI3 appears to be in good shape with the latest X.Org Server series and Direct Rendering Infrastructure 3 is even mandated by the Intel Mesa Vulkan driver, DRI2 is still the default with the xf86-video-intel DDX driver, similar to the situation in the Radeon DDX driver as well.

Radeon Open-Source vs. Catalyst With OpenCL CLPEAK

With yesterday having started to run some fresh basic OpenCL benchmarks on the open-source Radeon driver given the interesting remarks by some super-computing researchers about having more hope for the open-source drivers than the proprietary Catalyst, here are some results comparing the latest open-source AMD Radeon Linux driver code to the proprietary driver.

Catalyst vs. AMDGPU vs. Radeon DRM On A R9 290: Experimental AMDGPU Can Be Faster

While the AMDGPU Linux kernel driver right now exposes support for AMD GCN 1.2 GPUs and newer, like Carrizo, Fiji, and Tonga, it is possible to get GCN 1.1 Sea Islands hardware working with this driver if jumping through a few hoops. In this article are some tests of a Radeon R9 290 "Hawaii" when using the proprietary Catalyst driver, Radeon DRM driver as is the default for this card on open-source, and then using the experimental AMDGPU DRM open-source support.

Linux 4.5 AMDGPU/Radeon vs. Catalyst OpenGL Performance

With the first test release out this week for the Linux 4.5 kernel I have carried out some fresh benchmarks on different AMD Radeon graphics cards for comparing the very latest open-source driver performance against that of the proprietary AMD Linux driver. Here are how the competing AMD OpenGL Linux stacks are comparing to one another for starting off 2016.

New AMD GPU Performance To Be Boosted By Linux 4.5; How It Compares To The Binary Blob

Last week I posted some AMD proprietary vs. open-source AMD Linux driver benchmarks using the very latest code. Left out of that earlier comparison was the R9 Fury series with Fiji GPU as well as newer graphics cards using the Tonga GPU. These graphics cards are supported by the AMDGPU DRM driver rather than the long-standing Radeon DRM driver. As I've been mentioning a lot this week, Linux 4.5 will bring the PowerPlay power management / re-clocking support to AMDGPU. In this article are showing benchmarks of the Fiji and Tonga GPUs under Linux 4.4 and Linux 4.5 DRM-Next along with the Catalyst 15.9 driver as shipped by Ubuntu 15.10.

NVIDIA vs. Nouveau Linux Driver Performance With Extra Re-Clocking Patches

Last week I posted benchmarks of the AMD proprietary vs. open-source Radeon R600/RadeonSI Gallium3D drivers of various graphics cards on the newest open-source code. Today I'm doing a similar treatment on the NVIDIA GeForce side with seeing how their proprietary driver compares to the latest open-source Nouveau code.

Proprietary vs. Linux Git, Mesa 11.2-devel, DRI3 For R600g/RadeonSI

Following this week's OpenGL 4.1 R600g benchmarking with that newly-enabled OpenGL 4 support, I set out to run a larger hardware comparison on both the R600g and RadeonSI drivers as part of our year-end 2015 Linux benchmarking. In this article are tests of seven AMD Radeon graphics cards tested on the proprietary driver compared to the latest open-source driver stack -- with extra steps of enabling DRI3 rendering and also using the latest AMDGPU PowerPlay code.

With R600g Now Supporting OpenGL 4.1, See How The Open-Source Performance Compares To AMD Catalyst

There are two reasons for doing some end-of-the-year Radeon R600 Gallium3D driver testing with pre-GCN graphics cards. First, since the pre-GCN (HD 6000 series and older) support is being dropped by the new Radeon Software driver. Secondly, the R600g open-source driver finally supports OpenGL 4.1 for select GPUs. In this article is a look at the AMD Catalyst Linux driver with the last official release for HD 6000 series hardware compared to the very latest open-source Radeon graphics stack on Ubuntu Linux with a variety of interesting OpenGL Linux game tests.

Radeon DRM Linux 4.4 + Mesa 11.1 + DRI3 vs. AMD's Proprietary Driver

On Friday I posted benchmarks showing Nouveau's re-clocked performance relative to NVIDIA's proprietary driver for showing the performance potential of NVIDIA's GeForce GTX 600/700 series with the performance state code there beginning to work. That article was followed by AMDGPU driver tests on Linux 4.4 against Catalyst for the newest AMD GPU tech that uses this newer Direct Rendering Manager driver. The third test now is comparing the Radeon DRM performance on Linux 4.4 against AMD's binary blob when using older AMD GCN GPUs as well as a Northern Islands GPU for reference.

How Nouveau Compares To NVIDIA's Linux Driver When Kepler Re-Clocking Works

With the upcoming Linux 4.4 kernel, the Kepler re-clocking is in much better shape and for select GeForce GTX 600/700 series cards now allows the open-source driver to run them at their fully-rated clock frequencies. Here's some tests showing how Nouveau now compares to NVIDIA's proprietary Linux driver in such a comparison.
