With having added Tencent's NCNN tests to the Phoronix Test Suite with Vulkan acceleration, here is a look at the real-world impact by using RealSR-NCNN for scaling up with RealSR. Various NVIDIA GeForce and AMD Radeon graphics cards were tested for this initial NCNN / RealSR-NCNN Vulkan comparison.

The Mesa Radeon Vulkan driver "RADV" with its ACO back-end by default is now winning nearly across the board against not only AMD's AMDVLK Vulkan driver with LLVM back-end but also AMDGPU-PRO with the proprietary shader compiler back-end.

As part of re-testing all hardware prior to major GPU/driver launches, here is a look at the latest NVIDIA OpenCL/CUDA performance on Linux -- complementing the recent Blender 2.90 benchmarks and the latest NVIDIA vs. AMD Linux gaming performance. In still waiting to find out when we will get any NVIDIA Ampere hardware for Linux testing, I have been having some benchmarking fun and extended this to a 24-way graphics card comparison back to Maxwell in looking at not only the raw GPU compute performance but also the performance-per-Watt / power consumption and GPU thermal values.

With last week having delivered some current NVIDIA Linux gaming performance metrics ahead of the anticipated GeForce RTX 3000 "Ampere" series launch this week, here are some fresh compute metrics for those interested.

With NVIDIA next week expected to launch their next-generation GeForce RTX 3000 "Ampere" graphics cards, here is a fresh look at the current GeForce RTX 2000 series performance up against the latest AMD Radeon competition when using the very latest Linux graphics drivers for both vendors. This is the very latest performance showdown right now for the AMD/NVIDIA GPU performance under various Linux and Steam Play games on Ubuntu.

With the Mesa Radeon Vulkan driver "RADV" recently switching its default to the ACO shader compiler back-end that is developed with the support of Valve rather than the existing AMDGPU LLVM back-end that is the official open-source AMD shader compiler solution, here are some fresh Linux gaming benchmarks of the RADV driver on the in-development Mesa 20.2 comparing the now-default RADV+ACO configuration against that of the RADV AMDGPU LLVM back-end.

Going back to the end of 2018 was initial open-source "Nouveau" driver work on RTX 2000 / Turing GPUs as of Linux 5.0. But due to the lack of signed firmware images at the time, there was no actual hardware acceleration but just display/modesetting. The accelerated Turing support has come together recent so now here are benchmarks showing the open-source GeForce RTX 2060 and RTX 2080 performance of this open-source driver compared to the proprietary official driver.

Since its mainlining in Mesa 20.0, the Valve-backed ACO compiler back-end for the Radeon "RADV" Vulkan driver has been helping to reduce game load times and often increasing overall Linux gaming performance both for native titles as well as those on Steam Play with Proton+DXVK/VKD3D. With Mesa 20.1 releasing in the coming weeks, here are some recent benchmarks showing the RADV+ACO performance on Mesa 20.1-devel compared to RADV using its default AMDGPU LLVM back-end.

With last week's release of Radeon Software for Linux 20.10 as AMD's first packaged graphics driver update for Linux of 2020, here are some benchmarks showing how the performance compares to what is shipped by Ubuntu 18.04.4 LTS as well as when using the newer Mesa and Linux kernel releases for the very latest open-source performance, including switching over to RADV+ACO for Vulkan gaming.

For those using AMD Radeon "Navi" GPUs, the in-development Linux 5.7 kernel is delivering some minor performance improvements compared to prior kernels.

Released this month was the X-Plane 11.50 beta flight simulator that introduced a Vulkan renderer for this cross-platform, realistic flight simulator that long relied upon an OpenGL pipeline. Last week we published OpenGL vs. Vulkan X-Plane 11 benchmarks for both NVIDIA GeForce and AMD Radeon graphics. In this article is a look at the X-Plane 11.50 beta Vulkan performance across the different Radeon Vulkan driver options.

While Vulkan has had NVIDIA's ray-tracing extension (VK_NV_ray_tracing) extension, coming out today is Vulkan's first formal ray-tracing extension for cross-vendor/driver adoption.

Here is an up-to-date look at how the very latest Mesa 20.1 Git performance is for the Radeon "RADV" Vulkan driver both out-of-the-box and when enabling the Valve-backed ACO compiler back-end alternative to AMDGPU LLVM. Plus there are benchmarks of the latest AMDVLK open-source AMD Vulkan driver and also when using AMDGPU-PRO's Vulkan packages that still rely upon AMD's proprietary shader compiler.

Last week Basemark launched their Basemark GPU 1.2 benchmark that now includes Linux support alongside all other major supported desktop and mobile operating systems. We've been testing out this Linux version with OpenGL and Vulkan support on both AMD Radeon and NVIDIA GeForce hardware.

As it's been a few weeks since last running a Mesa open-source driver comparison on AMD Radeon graphics hardware, here are some fresh Mesa 20.1-devel benchmarks just a few weeks so far after the Mesa 20.0 branching. These latest Mesa 20.1-devel benchmarks were also run a second time when enabling the RADV ACO shader compiler back-end that's been a focus by Valve developers in enhancing the Linux gaming experience. These results are compared to Mesa 19.2.8 as a baseline for the open-source driver support offered out-of-the-box by Ubuntu 19.10.

With the release of Mesa 20.0 being imminent, here is a look at all of the new features for this first quarter update to the Mesa 3D stack for open-source OpenGL/Vulkan drivers.

Among many other Valve ACO back-end improvements for Mesa 20.0, one of the notable additions is this AMDGPU LLVM alternative now working for Radeon "Southern Islands" / GCN 1.0 graphics cards. With this, these original AMD GCN graphics cards may have some extra life out of Linux gaming boxes thanks to slightly higher performance some eight years after these graphics cards first launched in the Radeon HD 7000 series.

Yesterday we noted that the Linux kernel picked up a patch mitigating an Intel Gen9 graphics vulnerability. It didn't sound too bad at first but then seeing Ivy Bridge Gen7 and Haswell Gen7.5 graphics are also affected raised eyebrows especially with that requiring a much larger mitigation. Now in testing the performance impact, the current mitigation patches completely wreck the performance of Ivybridge/Haswell graphics performance.

Coming up next month already will mark four years since the release of Vulkan 1.0 but for today is an early surprise... Vulkan 1.2! The Khronos Group has prepared Vulkan 1.2 for release as the newest major update to this graphics and compute API. Several vendors also have Vulkan 1.2 support in tow.

As part of our year-end articles we already provided benchmarks looking at the Radeon OpenGL / Vulkan driver performance for 2019. That testing was done using Polaris and Vega given their GPU support prior to 2019, but for those wondering about the Radeon RX 5700 "Navi" performance for these GPUs that launched this summer, here are some end-of-year tests.

While the open-source Radeon Linux graphics stack has made some remarkable improvements this year not only from AMD but also the likes of Valve, unfortunately not as much can be said about the state of the open-source NVIDIA (Nouveau) driver. The Nouveau Linux graphics driver remains much slower than the proprietary driver, the hardware with the best support is several generations old, and due to the lack of signed firmware images there still isn't yet any open-source 3D for the Turing GPUs that have been shipping for months. But there may be hope in 2020.

For the latest of our year-end tests is a look at how the RadeonSI OpenGL driver and RADV Vulkan driver performance has evolved since the end of 2018 for Linux gaming.

The Mesa RADV Vulkan driver paired with the Valve-funded ACO compiler back-end is yielding an incredibly power competitor to AMD's own AMDVLK Vulkan driver that is derived from the source-code of their shared Windows Vulkan driver code-base. Here are some year-end benchmarks looking at the RADV vs. RADV ACO vs. AMDVLK Vulkan driver Linux gaming performance on Ubuntu with several generations of Radeon graphics hardware.

Mesa 19.3 could be released as soon as this week after being challenged by several delays over blocker bugs. This release should be making it out in the days ahead and is a fantastic Christmas gift to Linux desktop users and a big step-up for these OpenGL / Vulkan driver implementations as we end out 2019.

With AMD last week having enabled OpenGL 4.6 for their RadeonSI OpenGL Linux driver when enabling the NIR intermediate representation support, you may be wondering how using NIR is stacking up these days compared to the default TGSI route. Here are some benchmarks on Polaris, Vega, and Navi for comparing this driver option that ultimately allows OpenGL 4.6 to be flipped on.

It's been almost two months since last looking at the RADV ACO performance for this shader compiler back-end alternative to the AMDGPU LLVM code. ACO is making its debut in the upcoming Mesa 19.3 release while since the last round of testing have been more optimizations and fixes as well as getting the Navi/GFX10 support in place. In this article are some fresh benchmarks of the Vulkan RADV ACO support for not only Polaris and Vega but also the Radeon RX 5700 Navi graphics cards.

With Linux 5.4 due to be released this coming Sunday, 24 November, one of the big "winners" of this next kernel are AMD Radeon customers. Linux 5.4 brings support for new GPUs as well as better performance for existing graphics cards. Here are some fresh benchmarks of the performance wins as a result of the LRU bulk moves functionality.

With the upcoming Mesa 19.3 release one of the big new features is the "Zink" driver that provides a Mesa OpenGL implementation over Vulkan. This in theory allows for a generic OpenGL driver running over Vulkan hardware drivers, but there is a lot of work ahead before it's really a viable option.

For those curious about the performance of AMD Radeon open-source Linux gaming out-of-the-box on the newly released Ubuntu 19.10, here are those benchmarks compared to the Radeon driver state on Ubuntu 19.04. Additionally, there are benchmark results if manually upgrading your Ubuntu 19.10 installation to using the in-development Linux 5.4 kernel and Mesa 19.3 for the very newest AMD Linux driver support.

With picking up the Dell XPS 7390 with Intel Core i7-1065G7 for being able to deliver timely benchmarks from Intel's long-awaited 10nm+ Icelake generation, one of the first areas we have been testing is the Iris Plus "Gen 11" graphics performance. In this article are our initial Windows 10 vs. Linux graphics performance numbers for Ice Lake.
