With the initial Iris Gallium3D driver that was merged into Mesa at the end of February from our tests on UHD Graphics the performance is quite promising considering the early stage of this new open-source OpenGL driver and it not yet being fully tuned/optimized. The Iris Gallium3D driver support goes back to Broadwell CPUs so I decided to run some benchmarks with the legendary Core i7 5775C that features the Iris Pro Graphics 6200 with 128MB of eDRAM.

With yesterday's somewhat of a surprise announcement that Intel is ready to mainline their experimental Iris Gallium3D driver as their "modern" Linux OpenGL driver with numerous design advantages over their long-standing "classic" i965 Mesa driver, here are some fresh benchmarks of that latest driver compared to the current state of their OpenGL driver in Mesa 19.1.

It's been a number of months since last trying the RadeonSI NIR back-end, which is being developed as part of the OpenGL 4.6 SPIR-V bits for this AMD OpenGL driver, but eventually RadeonSI may end up switching from TGSI to NIR by default. Given the time since we last tried it out and the increasing popularity of NIR, this weekend I did some fresh tests of the NIR back-end with a Radeon Vega graphics card.

With today's launch benchmarks of the AMD Radeon VII graphics card on Linux, tests were done using the latest Linux 5.0 Git kernel as well as Mesa 19.0 providing the OpenGL/Gallium3D drivers. Details on the support going back to older releases were covered, but in this article is looking at the performance difference between those recent Linux kernel and Mesa releases.

Taking many by surprise less than one month after NVIDIA announced "G-SYNC Compatible" in supporting FreeSync/Adaptive-Sync displays as an alternative to the more expensive dedicated G-SYNC monitors, the newest Linux beta graphics driver has support for this gamer-oriented feature. This comes just a matter of days after NVIDIA began shipping their Windows driver with this dynamic refresh rate feature that aims to eliminate or at least reduce tearing and stuttering.

With yesterday having posted fresh OpenGL/Vulkan Linux gaming benchmarks for the current NVIDIA GeForce and AMD Radeon graphics cards, in this article is the freshest OpenCL GPU compute data for that set of 14 graphics cards on the very latest Linux graphics driver stack. In the case of AMD Radeon open-source compute, it was tested using the new ROCm 2.0 atop the mainline Linux 5.0 kernel and Ubuntu 18.10.

With the AMD Radeon VII graphics card shipping in two weeks as the second-generation Vega GPU at 7nm, I figured it would be an interesting time to see how far the original Radeon RX Vega 56 and RX Vega 64 graphics card performance has evolved since their launch back in August 2017. Here is a fresh look at the current Radeon RX Vega 56/64 GPU performance today using the bleeding-edge Linux graphics drivers compared to the driver state back in 2017 for OpenGL and Vulkan gaming performance.

With Mesa 19.0 entering its feature freeze before the month is through, here are fresh benchmarks of the very latest RadeonSI OpenGL and RADV Vulkan performance on Polaris and Vega graphics cards compared to the current stable Mesa 18.3 series and the former 18.2 release. This testing is complementary to last week's Mesa 19.0 RADV vs. AMDVLK vs. AMDGPU-PRO Vulkan tests.

When recently publishing the PlaidML deep learning benchmarks and lczero chess neural network OpenCL tests, some Phoronix readers mentioned they were seeing vastly different results with using the PAL OpenCL driver in AMDGPU-PRO (Radeon Software) compared to using the ROCm compute stack. So for seeing how those two separate AMD OpenCL drivers compare, here are some benchmark results with a Vega GPU while testing ROCm 2.0 and AMDGPU-PRO 18.50.

The open-source Radeon Linux graphics driver stack saw some nice RADV Vulkan performance improvements over the course of this year as well as to the RadeonSI Gallium3D driver performance, but how did the NVIDIA Linux driver stack perform this year for gaming? Here are some benchmarks showing it too saw some nice Linux gaming performance boosts this year with subsequent driver updates.

Last week AMD officially released ROCm 2.0 as the newest major release of the Radeon Open Compute stack. Here are some initial benchmark figures for that Radeon Linux compute component on Polaris and Vega hardware.

This year the focus for modern Linux gaming really shifted to Vulkan with Feral's major new game ports being exclusively Vulkan-based, DXVK and Steam Play coming about for relying upon Vulkan for Direct3D 10/11 emulation on Linux, Vulkan 1.1 and subsequent point releases ironing out desired functionality by developers for this graphics API, and all of the open/closed-source drivers continuing to mature. But there is still a plethora of OpenGL-only Linux games out there and AMD's open-source driver team hasn't let up in continuing to improve and optimize their RadeonSI Gallium3D driver. Here are some benchmarks showing how the RadeonSI performance has improved over the past year on an AMD RX Vega graphics card.

As the latest from our year-end Linux benchmarks, here are tests when seeing how Mesa's RADV open-source Radeon Vulkan driver performance has evolved for Linux gaming. With a Radeon RX Vega 64 graphics card, the performance was looked at from Mesa 17.3 through Mesa 19.0-devel for showing the driver's evolution.

While Windows users last week were greeted by the Radeon Software Adrenalin 2019 driver on the Linux side was the Radeon Software for Linux 18.50 release. The only listed public change for this 18.50 Linux hybrid driver build was RHEL 7.6 support, but I've since been able to test and confirm that the Radeon RX 590 is working with this new Linux driver package. As a result, here is a look at the Radeon RX 590 performance from this "AMDGPU-PRO" driver build compared to the latest open-source driver stack in the form of Linux 4.20 with Mesa 19.0-devel.

Following the GeForce RTX 2080 Linux gaming benchmarks last week with now having that non-Ti variant, I carried out some fresh GPU compute benchmarks of the higher-end NVIDIA GeForce and AMD Radeon graphics cards. Here's a look at the OpenCL performance between the competing vendors plus some fresh CUDA benchmarks as well as NVIDIA GPU Cloud TensorFlow Docker benchmarks.

One of the most exciting developments in the open-source Intel driver space this year was the Iris Gallium3D driver taking shape as what's destined to eventually succeed their "classic" i965 Mesa driver. With Iris Gallium3D maturing, here's a look at how the performance currently stacks up to their mature OpenGL driver.

As it's been a while since last looking at the NVIDIA vs. Nouveau Linux OpenGL driver performance, here's a look at the current performance difference as the end of the year quickly approaches. This benchmarking roundabout features multiple generations of GeForce GPUs while testing with the NVIDIA 415 proprietary driver against the Nouveau stack on Linux 4.19 and Mesa 19.0-devel.

Given the AMDGPU changes building up for DRM-Next to premiere in Linux 4.21 that is on top of the AMDGPU performance boost with Linux 4.20, here are some benchmarks of Linux 4.19 vs. 4.20 Git vs. DRM-Next (Linux 4.21 material) with the Radeon RX Vega 64 compared to the relevant NVIDIA GeForce competition.

Released this week was AMDVLK 2018.4.2 having been released this past week as the newest open-source AMD Vulkan driver code derived from their official Vulkan driver code-base but with using the AMDGPU LLVM compiler back-end over their proprietary shader compiler. For your latest Vulkan benchmark viewing pleasure is a look at this newest AMDVLK release compared to AMDGPU-PRO 18.40 (the same fundamental Vulkan driver but with the closed-source shader compiler) and then the RADV Vulkan drivers in the form of Mesa 18.2 stable and the now in-development Mesa 19.0. These four AMD Radeon Vulkan driver combinations were tested on Fiji, Polaris, and Vega graphics processors.

This week marked the release of Radeon Software 18.40 as the latest release of AMD's Linux driver stack targeting workstation users. While the sole mentioned change was the addition of SUSE Linux Enterprise 15 support, I decided to run some benchmarks of this latest driver compared to the other open-source Radeon Linux driver options.

Given AMD's weekly updating of the public AMDVLK Vulkan driver source tree as their official open-source Vulkan Linux driver while RADV continues to be maintained as the popular open-source Radeon Vulkan driver within the Mesa source tree, here is a fresh look at how those competing drivers perform. Additionally there are the results from Radeon Software / AMDGPU-PRO using its closed-source Vulkan driver that is derived from the same sources as AMDVLK but built against AMD's proprietary shader compiler.

With the two main set of AMDGPU DRM driver updates merged (one and two) to DRM-Next ahead of the next Linux kernel cycle, I decided to run some benchmarks on this code using Vega and Polaris hardware for seeing how the performance compares to that of the Linux 4.18 stable and Linux 4.19 Git kernels.

Here is a fresh look at the current Linux OpenGL/Vulkan performance of various new and old Intel/AMD systems with integrated graphics using Ubuntu 18.10.

There is one week to go until NVIDIA begins shipping the GeForce RTX 2080 "Turing" series but while waiting for that hardware, here is a look back at how various graphics cards are performing for Linux games from the GTX 1000 Pascal series back through the GTX 600 Kepler series. On the AMD side in this comparison is also going from Vega back to the GCN 1.0 Southern Islands. The Vulkan/OpenGL Linux gaming performance is being looked at as well as the overall system power consumption and performance-per-Watt.

Here are the results from some weekend benchmarking looking at the current stage of the AMDGPU + RadeonSI/RADV open-source AMD Linux graphics card performance when using the very latest code from the Linux 4.19 development kernel and Mesa 18.3. It's also an interesting mix of AMD Radeon graphics cards from the HD 7950 through the latest RX Vega 64.

Last week NVIDIA released the 396.54 driver that has a significant performance fix for OpenGL/Vulkan Linux performance due to a resource leak regression introduced at the start of the 390 driver series. With that updated driver (also as of yesterday back-ported to 390.87 too), there is a measurable boost in performance after running a few games on NVIDIA Linux systems. But at the same time, the Mesa 18.3-dev open-source graphics driver stack with RadeonSI/RADV continues improving on the open-source AMD front. Here is a fresh look at how the latest AMD Radeon and NVIDIA GeForce graphics cards compare using these latest drivers.

Last week AMD released the AMDGPU-PRO 18.30 hybrid driver featuring their latest optional proprietary Linux driver components as well as the "all-open" driver stack option. Here are some initial benchmarks of that driver stack compared to what's shipped by default in Ubuntu 18.04.1 LTS as well as the latest upstream Mesa/AMDGPU support.

Yesterday NVIDIA released the 396.54 Linux driver update and while from being another point release might feel like a mundane update hot on the heels of the GeForce RTX 2070/2080 series debut, it's actually a significant driver update for Linux gamers. Here are some benchmarks showcasing the performance fix that warranted this new driver release.

It's been a while since last delivering any benchmarks focused on the NVIDIA OpenCL compute performance, but for those curious, here are some fresh GPGPU performance numbers using the latest NVIDIA Linux driver release while testing from Ubuntu 18.04 LTS.

Being roughly mid-way through the Linux 4.18 kernel development cycle, I spent some time this weekend running benchmarks of the AMDGPU DRM driver on Linux 4.18 Git compared to Linux 4.17 stable on three different Radeon graphics cards while using the Mesa 18.1.3 based drivers.
