Nouveau Open-Source NVIDIA Tests On Linux 4.8, Mesa 12.1-dev

I haven't run any Nouveau driver benchmarks recently for looking at the open-source NVIDIA Linux performance since there hasn't been too much progress, particularly when it comes to re-clocking of the desktop GPUs for delivering better performance. However, with all the testing I've been doing on the Radeon side with Linux 4.8 and Mesa 12.1-dev Git, I decided to do a comparison with a few NVIDIA GeForce GPUs under this latest open-source driver stack.

AMDGPU-PRO Radeon RX 460/470/480 vs. NVIDIA Linux GPU Benchmarks

Last week I published an 18-way GPU Linux comparison featuring the new Radeon RX 460 and RX 470 graphics cards along with other AMD Radeon and NVIDIA GeForce GPUs. The Radeon tests were done using the very latest open-source Linux driver stack while in this article are similar benchmarks done but using the AMDGPU-PRO hybrid driver stack.

AMDGPU-PRO Beta 2 vs. Mesa 11.3 + Linux 4.6: Very Competitive For Linux Gamers

Following last week's AMDGPU-PRO 16.20.3 "Beta 2" driver release of AMD's new hybrid driver stack for Linux that makes use of the AMDGPU open-source kernel DRM driver with the closed-source OpenGL driver derived from Catalyst / Radeon Software, I set out to do a fresh open vs. closed-source driver comparison. For the Radeon R9 285, R9 290, and R9 Fury, I compared the performance of this new AMDGPU-PRO driver against Mesa 11.3-devel Git and Linux 4.6 for the latest open-source driver stack.

Intel Skylake Performance Boosted By Mesa 11.3

This past week I showed how Intel Broadwell graphics are much faster with Mesa 11.3 but this new Mesa version doesn't do much for Haswell. Similar to Broadwell, Mesa 11.3 is a big win if you are on Intel's latest-generation Skylake hardware.

AMDGPU DRM For Linux 4.7 Will Bring Some Performance Boosts For The R9 Fury

Yesterday I published some Radeon DRM-Next performance tests for the Radeon DRM code queued up for the Linux 4.7 kernel merge window. Today I'm testing the DRM-Next-4.7 code for AMDGPU for looking at the performance improvements coming to this newer AMD DRM driver with the next Linux kernel cycle. The DRM-Next-4.7 performance was compared to Linux 4.6 in this article for a Tonga and Fiji graphics card.

Fresh Mesa 11.3-devel RadeonSI Tests On Ubuntu 16.04 vs. NVIDIA's 364.19 Driver

For some end-of-month benchmarks and while having a number of graphics cards out prior to being let down by Tomb Raider's Linux benchmark, here is a fresh round of OpenGL tests while using the newest Mesa 11.3-devel code on RadeonSI with AMDGPU/Radeon DRM from Ubuntu 16.04 and then compared to various Kepler/Maxwell graphics cards with the newest NVIDIA Linux driver.

Nouveau With Boost Patches Are Now Competitive To Radeon/AMDGPU With RadeonSI

Last week I published benchmarks showing Nouveau's "boost" patches offering much performance potential compared to the current state of the open-source NVIDIA Linux graphics driver but generally still not enough performance to compete with NVIDIA's proprietary Linux graphics driver. I've since carried out some fresh open-source AMD Linux results for reference to see how the NVIDIA vs. AMD GPU open-source speeds are comparing.

Nouveau "Boost" Patches Show Much Performance Potential

Karol Herbst has been one of the independent developers leading the charge to improve Nouveau re-clocking support. Within his Git tree he's been queuing up re-clocking and voltage handling improvements for this reverse-engineered NVIDIA Linux driver. He's hoping the improved re-clocking code will be ready for the Linux 4.7~4.8 kernel, but I decided to try out his Git tree this week for some benchmarking of this experimental support.

Nouveau Kepler On Linux 4.6 vs. NVIDIA's 364 Proprietary Driver

We've already looked at the GeForce 900 series performance on Nouveau with the Linux 4.6 kernel that finally has the necessary bits for supporting 3D hardware acceleration on these Maxwell GPUs. Those GTX 900 series results didn't end up being particularly exciting since there isn't yet any re-clocking support on this open-source NVIDIA Linux driver. For complementing those results are some GeForce 600/700 "Kepler" graphics card results when comparing Nouveau on Linux 4.6 with Mesa 11.3-devel and using re-clocking then compared to the latest NVIDIA proprietary driver.

Nouveau Kepler vs. Maxwell Performance On Linux 4.6 + Mesa 11.3-dev

For putting the open-source GeForce GTX 900 driver performance into better perspective from the results this week with the new support found on Linux 4.6 and compared to NVIDIA's proprietary driver, hare are some benchmark results when comparing the Nouveau driver performance of the GTX 900 "Maxwell" graphics cards to that of the GTX 600/700 "Kepler" graphics cards with their experimental re-clocking support.

Radeon + AMDGPU Performance On Linux 4.6

For those curious whether the Linux 4.6 kernel is bringing any noticeable performance improvements to the AMDGPU and Radeon DRM drivers over Linux 4.5, here are some benchmarks in conjunction with using Mesa 11.3-devel built against LLVM 3.8.

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.
