For your viewing pleasure this Friday are some open-source AMD vs. NVIDIA numbers when using the latest open-source code on each side. Linux 4.9-rc1 was used while Ubuntu 16.10 paired with the Padoka PPA led to Mesa Git as of earlier this week plus LLVM 4.0 SVN. As covered recently, there are no Nouveau driver changes for Linux 4.9 while we had hoped the boost patches would land. Thus the re-clocking is still quite poor for this open-source NVIDIA driver stack. For the Nouveau tests I manually re-clocked each graphics card to the highest performance state (0f) after first re-clocking the cards to the 0a performance state for helping some of the GPUs that otherwise fail with memory re-clocking at 0f, as Nouveau developers have expressed this is the preferred approach for testing.
I have pushed out new ISO files for the Wayland Live CD project, named after my favorite celebrity (Rebecca Black).
The Live CD Linux distribution focused on showcasing the potential of Wayland across different desktops, toolkits, and applications is out with a new ISO release.
Developer and Phoronix reader "Nerdopolis" has announced the latest version of his RebeccaBlackOS that packages up the latest Wayland/Weston code and other software supporting Wayland. He announced, "I have pushed out new ISO files for the Wayland Live CD project, named after my favorite celebrity (Rebecca Black). I wanted to time the release to celebrate the release of her new song The Great Divide, but I had some issues I previously had to resolve This might be the last set of ISOs I announce here. I will post newer ISOs/commits, but probably won't announce to the Wayland mailing list."
Now that the RADV Radeon Vulkan driver has landed in Mesa Git and Linux 4.9-rc1 is out, I figured it was time for some fresh benchmarks of the Radeon Vulkan driver against the RadeonSI Gallium3D OpenGL driver. Here is the first of that new data.
For some Sunday benchmarking fun was testing RADV Vulkan vs. RadeonSI OpenGL for Dota 2, the best Vulkan benchmark on Linux to date. In addition to looking at the latest performance results, the Phoronix Test Suite was looking at the CPU utilization in both scenarios too (by setting the MONITOR=cpu.usage environment variable). The OpenGL vs. Vulkan tests were done at a variety of resolutions.
It's been a while since last delivering any open-source NVIDIA (Nouveau) Gallium3D driver benchmarks but for your viewing pleasure this Friday are some fresh Kepler and Maxwell test results for this reverse-engineered NVIDIA Linux driver code against the proprietary NVIDIA driver in various OpenGL test cases.
As of today Mesa now has full OpenGL 4.4 support (with 4.5 already done) for both AMD radeonsi and Intel (i965/gen8+). Mesa won't actually expose any higher than OpenGL 4.3 until Mesa (well, someone) pays up for the Conformance Tests.
The AMD developer Marek Olšák sent over a patch to Mesa for the AMD radeonsi driver that he found by luck, and it improves DiRT: Showdown on Ultra settings by 15%. It's likely of course that this can help other games too. Thanks to Phoronix for pointing it out.
It does of course make me wonder: Just how many gotchas like this are hidden in Mesa, and how many other general improvements can be made? I'm betting there's quite a few.
Now that the RADV Radeon Vulkan driver is part of mainline Mesa, it's increasingly easy to experiment with this unofficial, open-source Vulkan driver on rolling-release distributions and through third-party package archives/repositories.
One of the popular choices for Linux gamers and enthusiasts on Ubuntu, the Padoka PPA, has added support for building the Radeon Vulkan driver with its most recent update over the weekend. The Padoka PPA is now building its Mesa packages with support for the Radeon Vulkan (RADV) driver to complement the existing Intel Vulkan (ANV) support. The Mesa Git code continues to be built against LLVM 3.0 SVN for the best AMDGPU LLVM back-end support too.
Back in April I did tests showing how Intel's Clear Linux distribution showed much potential for HD/Iris Graphics performance, something that intrigued many Phoronix readers since Clear Linux would generally be seen as a workstation/cloud/container-optimized Linux distribution and something with not much emphasis on the desktop or gaming. Those earlier tests were with Ubuntu 16.04, bur with Ubuntu 16.10 coming out this week, here are some fresh tests of Clear Linux and Ubuntu Yakkety Yak on an Skylake HD Graphics system.
For curiosity sake, I ran some fresh Ubuntu 16.10 vs. Clear Linux (10820) benchmarks on the same Core i5 6600K system with an MSI Z170A GAMING PRO motherboard, 16GB DDR4-2133MHz memory, and 256GB TS256GSSD370S SSD. The mid-range i5-6600K is equipped with HD Graphics 530.
