There's a lot of benchmarking going on this weekend at Phoronix in preparation for next week's Radeon RX 480 Linux review. Here are some fresh results on the NVIDIA side showing the current performance-per-dollar data for the NVIDIA Maxwell and Pascal graphics cards for seeing what the RX 480 "Polaris 10" card will be competing against under Linux.
Not that I can share any early benchmark figures or anything of the Radeon RX 480 "Polaris" graphics card, but the testing commenced today... But I can at least share a couple images.
Yep, AMD sent over a Radeon RX 480 graphics card for being able to provide launch-day Linux benchmarks next week. That day is 29 June when the embargo expires and the RX 480 cards will begin to hit stores for the $199+ price-tag (or slightly more for the 8GB version).
With the imminent Mesa 12.0 release there is now OpenGL 4.3 compliance for Intel Broadwell graphics hardware and newer, rather than OpenGL 3.3 as was the upper limit in the Intel Mesa driver to this point. Now having OpenGL 4.x support with this open-source Intel driver, I decided to see how various OpenGL 4.x games are running with the Intel driver when using a Skylake CPU sporting HD Graphics 530.
Yesterday I mentioned how the AMDGPU driver needed some important last minute fixes for the soon-to-launch Radeon RX 480 "Polaris" support. Those patches are now pending to be pulled as part of the next round of DRM fixes heading into Linux 4.7.
Just weeks after their first round of DRM updates for Linux 4.8 were submitted, the Intel crew has their second -- of a possible three -- feature updates readied for the Linux 4.8 kernel via DRM-Next.
As expected, the fourth and last RC (Release Candidate) build of the upcoming Mesa 3D Graphics Library 12.0.0 has been announced on June 21, 2016, by Collabora's Emil Velikov.
Mesa 3D Graphics Library 12.0.0 Release Candidate 4 incorporates the latest fixes and improvements that the development team behind the open-source Mesa 3D project managed to introduce during the last week, since the release of the third Mesa 3D 12.0.0 RC build.
Timothy Arceri of Collabora has prepped the latest version of his massive patch-set for providing an on-disk shader cache for Mesa, albeit focused for now on the Intel DRI driver.
Emil Velikov announced the release this morning of the fourth and final planned release candidate for Mesa 12.0.
Mesa 12 is a monstrous release with a lot new OpenGL 4 support across the major drivers and tons of other improvements: learn more via The 12 Big New Features Of Mesa 12.0.
With the recent report that Intel's Vulkan Linux driver should now work with Dota 2, I was curious to test out the game -- and Talos Principle -- with the latest Mesa Git code that houses this open-source "Anvil" Vulkan driver.
With the Padoka PPA now shipping the Intel Vulkan driver by default, it's super easy on Ubuntu-based Linux systems to fetch a Mesa Git snapshot within the past day or two that does have the Vulkan driver for Intel hardware built and enabled. So that's what I went with for trying Mesa 12.1-dev state of the Intel Vulkan driver as of today on a Core i5 6600K "Skylake" box running Ubuntu 16.04.
With this weekend's 5-Way Mesa 12.1-dev + Linux 4.7 Git Radeon Comparison and other tests I've done on Linux 4.7 Git with Radeon hardware, the R9 290 has regressed to the point of performing noticeably worse than other AMD GCN GPUs... Many other Phoronix readers with different Rx 200/300 graphics cards have also confirmed their graphics cards performing poorly on Linux 4.7.
The newest OpenGL extension now supported by Mesa is GL_EXT_window_rectangles.
GL_EXT_window_rectangles is a newer OpenGL extension and explained via the OpenGL.org registry, "this extension provides additional orthogonally aligned 'window rectangles' specified in window-space coordinates that restrict rasterization of all primitive types (geometry, images, paths) and framebuffer clears."
Following the massive Windows 10 vs. Ubuntu 16.04 Graphics Performance With Radeon Software, AMDGPU-PRO, AMDGPU+RadeonSI article, I immediately started work on my next article... In preparation for a hardware launch Linux testing later this month, I started testing my collection of AMD cards on Linux 4.7 and Mesa 12.1-dev. Here are some of those results if you are curious, including performance-per-Watt metrics.
The cards tested so far this weekend on this bleeding-edge driver stack were the R9 270X, R9 285, R9 290, R7 370, and R9 Fury. Mesa 12.1-dev was from Git yesterday using the Padoka PPA and also built with LLVM 3.9 SVN. The Linux 4.7 kernel was from Git in the Ubuntu Mainline Kernel PPA this week.
Yesterday I published some Windows 10 vs. Ubuntu 16.04 Linux gaming benchmarks using the GeForce GTX 1070 and GTX 1080 graphics cards. Those numbers were interesting with the NVIDIA proprietary driver but for benchmarking this weekend are Windows 10 results with Radeon Software compared to Ubuntu 16.04 running the new AMDGPU-PRO hybrid driver as well as the latest Git code for a pure open-source driver stack.
For your viewing pleasure this Friday is our largest Windows vs. Linux graphics/gaming performance comparison ever conducted at Phoronix in the past 12 years! With the brand new NVIDIA GeForce GTX 1070 and GTX 1080 graphics cards, their performance was compared under Windows 10 Pro x64 and Ubuntu 16.04 x86_64 when using the very latest NVIDIA Corp drivers for each OS. A range of Steam gaming benchmarks and more were done, including some cross-platform Vulkan graphics benchmarks. Continue on for this interesting comparison.
Collabora's Emil Velikov has announced the release and general availability of the third and likely the last RC (Release Candidate) build of the upcoming Mesa 12.0.0 3D Graphics Library.
Mesa 3D Graphics Library 12.0.0 Release Candidate 3 arrives more than a week after the second RC version, bringing a total of 111 changes to most of the included graphics drivers and components. The full changelog has been attached at the end of the article just in case you're wondering what's new in this update.
