Radeon RX 6600 Linux Performance Rising Even Higher With Newest Open-Source Driver

Filed under
Graphics/Benchmarks

Just one week ago was the public launch of the Radeon RX 6600 as the newest offering in the RDNA2 GPU line-up. While in our Radeon RX 6600 Linux review the performance was good on AMD's well regarded open-source driver stack and standing ground against the likes of the GeForce RTX 3060 with NVIDIA's proprietary Linux driver, it turns out the RX 6600 Linux performance can be even better already. Here are benchmarks of the Radeon RX 6600 on Linux across six different driver configurations.

In particular, it appears that the driver state around 1 October that was used for the launch-day RX 6600 Linux review is actually less than ideal -- there appears to have been a regression around that point and with newer (as well as 21.2 stable) driver code there can be measurable gains to Linux gaming performance.

  • Intel teases 'software-defined silicon' with Linux kernel contribution – and won't say why

    Intel has teased a new tech it calls "Software Defined Silicon" (SDSi) but is saying almost nothing about it – and has told The Register it could amount to nothing.

    SDSi popped up around three weeks ago in a post to the Linux Kernel mailing list, in which an Intel Linux software engineer named David Box described it as "a post-manufacturing mechanism for activating additional silicon features".

  • RadeonSI Lands Another "Very Large" Optimization To Further Boost SPECViewPerf - Phoronix

    In recent months we have seen a lot of RadeonSI optimizations focused on SPECViewPerf with AMD seemingly trying to get this open-source OpenGL driver into very capable shape moving forward for workstation GL workloads. Hitting Mesa 22.0-devel today is yet another round of patches for tuning SPECViewPerf.

  • Vendors Including NVIDIA Talk Up New OpenCL Extensions For Vulkan Interop, NN Inference - Phoronix

    Last Friday night we spotted OpenCL 3.0.9 with several new extensions included. Today The Khronos Group is formally announcing these latest OpenCL additions focused on Vulkan interoperability as well as neural network inferencing.

    These new extensions for OpenCL 3.0 include an integer dot product extension for neural network inferencing (cl_khr_integer_dot_product) with a focus on 8-bit integer support.

  • RadeonSI Enables NGG Shader Culling For Navi 1x Consumer GPUs - Phoronix

    As another possible performance win for RadeonSI Gallium3D as AMD's open-source Radeon OpenGL driver on Linux systems is enabling of NGG culling for Navi 1x consumer graphics processors rather than limiting it only to newer Navi 2x (RDNA2) GPUs.

    Merged on Monday was a patch to enable shader culling for Navi 1x consumer SKUs with no longer limiting it to Navi 2x / GFX10.3 or when using various debug options. This culling was also enabled for Navi 1x GPUs but only for the "Pro" graphics SKUs.

Ubuntu 21.10 Radeon Gaming With KDE Plasma vs. GNOME Shell + Wayland vs. X.Org

Filed under
Graphics/Benchmarks

With last week's release of Ubuntu 21.10, here are some fresh benchmarks looking at the Linux gaming performance on this new release while testing both the GNOME Shell 40 default desktop to that of its KDE Plasma 5.22 based option. Both the X.Org and Wayland sessions for KDE and GNOME were benchmarked for seeing how the Linux gaming performance compares with the Radeon open-source GPU driver stack.

In the past we've seen the GNOME Shell Wayland-based Linux gaming experience to be in very good shape and in some games performing even better than the X.Org based environment. With GNOME / Mutter continuing to mature as well as running the latest open-source Radeon drivers, now with the Ubuntu 21.10 release it's a good time to re-test the performance. Additionally, the KDE Plasma Wayland experience has matured a heck of a lot this year and is now in much better shape for day-to-day use so it's been also included for this comparison.

NVIDIA 495 Linux Beta Driver Released

  • NVIDIA 495 Linux Beta Driver Released With GBM Support - Phoronix

    NVIDIA 495.29.05 is out today as the first public Linux driver in the 495 series.

    Most exciting with the NVIDIA 495.29.05 beta release is GBM API support! After years of waiting and NVIDIA wanting to pursue an alternative API instead after years of pushing EGLStreams, NVIDIA's proprietary driver has finally adopted the Generic Buffer Manager (GBM) API. This greatly enhances the Wayland support for NVIDIA's proprietary driver stack and makes it compatible with a lot more Wayland software. For example, the likes of Sway should now run fine with this new driver.

  • NVIDIA Beta 495.29.05 rolls out with GBM for expanded Wayland support | GamingOnLinux

    NVIDIA has today released the 495.29.05 driver as a Beta in their New Feature Branch and it's a relatively big one.

    The main highlight feature is that NVIDIA has finally added support for the GBM API making it more compatible with Wayland, this is instead of EGLStreams that they were previously pushing. Just another tick in the box for running a Wayland system with NVIDIA with it now using the same API as Mesa with GBM.

  • Mesa 21.3 Fixes Issue Of Some Games Having Transparency Issues Under Wayland - Phoronix

    Landing in time for the imminent Mesa 21.3 feature freeze / code branching is support for the EGL_EXT_present_opaque extension on Wayland. While this EGL extension may not sound too exciting, for some OpenGL games on Wayland it will address some transparency issues.

    The issue stems from this issue ticket opened during the summer by game porter Ethan Lee. The issue is around needing an EGL equivalent to VkCompositeAlphaFlagBitsKHR as "we've got a whole lot of games that are unintentionally translucent in Wayland." Portal 2 is among the games as a result having issues under native Wayland.

  • Vulkan 1.2.196 Introduces H.265 Encode Extension - Phoronix

    Arriving back in April were the initial Vulkan Video extensions that included support for video decode of H.264 and H.265 while the initial video encode support was limited to H.264. Out today with Vulkan 1.2.196 is the new extension allowing for H.265 encoding with this new industry-standard video API.

    Vulkan 1.2.196 introduces the provisional VK_EXT_video_encode_h265 extension. This extension was worked on by AMD, Intel, and NVIDIA but at least under Linux only the NVIDIA proprietary driver currently exposes Vulkan Video encode/decode support. Presumably this morning NVIDIA will be issuing a new Vulkan beta driver providing timely support for this new H.265 encode provisional extension.

Pumpkins, markets, and one bad Apple

Imagine your local farmers market: every Saturday the whole town comes together to purchase fresh and homemade goods, enjoy the entertainment, and find that there is always something for everyone. Whatever you need, you can find it here, and anyone can sign up to have their own little stand. It is a wonderful place, or so it seems. Now, imagine starting out as a pumpkin farmer, and you want to sell your pumpkins at this market. The market owner asks 30% of every pumpkin that you sell. It's steep, but the market owner -- we'll call him Mr. Apple -- owns all the markets in your area, so you have little choice. Let's continue this analogy and imagine that, since it is a little hard for you to make ends meet, you decide to tell your customers that they can come visit you at your farm to purchase pumpkins. Mr. Apple overhears and shuts your stand down. You explain that your business cannot be profitable this way, but the grumpy market owner says that you can either comply or find another place. At the end of your rope, you look for information about starting your own farmers market, but it seems Mr. Apple owns every building in town. In the midst of Apple announcing its new products, attention is drawn away from its ongoing battle to maintain its subjugation over users globally. The Netherlands’ Authority for Consumers and Markets (ACM) last month informed the U.S. technology giant of its decision that the rules around the in-app payment system are anticompetitive, making it the first antitrust regulator to conclude that the company has abused market power in the App Store. And while Apple is appealing this verdict, the European Union is charging the company with another antitrust claim concerning the App Store. Read more
