Open-Source NVIDIA GeForce RTX 2000 "Turing" 3D Driver Performance

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.

The Current RADV+ACO Mesa Driver Performance For February 2020

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.

Valve's ACO Helps Put New Life Into Radeon GCN 1.0 GPUs With ~9% Better Linux Gaming Performance

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.

Intel's Mitigation For CVE-2019-14615 Graphics Vulnerability Obliterates Gen7 iGPU Performance

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.

How The Radeon RX 5700 XT Navi Linux Performance Has Evolved Since Launch

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.

The Open-Source NVIDIA/Nouveau vs. NVIDIA Linux Driver At The End Of 2019 - Poor But A Lot Of Hope

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.

Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

Intel's New OpenGL Driver Is Looking Really Great With The Upcoming Mesa 19.2

Intel's new open-source OpenGL Linux driver "Iris" Gallium3D that has been in development for the past two years or so is getting ready to enter the limelight. Months ago they talked of plans to have it ready to become their default OpenGL driver by the end of the calendar year and with the state of Mesa 19.2 it's looking like that goal can be realized in time. With our new tests of this driver, in most games and other graphics applications the performance of this Gallium3D driver is now beyond that of their "classic" i965 Mesa driver.
