Early Benchmarks Of Linux 4.10 Show Some Improvements & Regressions For Core i7-6800K

Linux

This New Year's Eve I finished up some benchmarks of the Linux 4.5 through Linux 4.10 Git kernels on a powerful Core i7 6800K "Broadwell-E" system. I found some improvements with 4.10 Git, but there are also some evident regressions.

I'll have more benchmark results in the New Year as time allows and the 4.10 development settling down, but from the tests I did so far on the Core i7 6800K system there is some concern over what appears to be some definite and noticeable regressions.

  • Skylake Iris Pro Graphics: Ubuntu, Fedora, openSUSE, Antergos, Clear Linux Benchmarks

    For those craving some more end-of-year Linux distribution benchmarks, this morning I finished carrying out a fresh Linux distro comparison focusing upon the Intel OpenGL performance when making use of "Skylake" Iris Pro hardware. For this New Year's Eve benchmarking fun was Ubuntu, Fedora, openSUSE, Antergos, and Clear Linux.

  • Mesa Saw More Than 10,000 Commits This Year From Record Number Of Contributors

    Unless Marek delivers another one of his big patch-sets to provide some new feature/improvement to RadeonSI, the OpenGL shader cache magically lands, or some other big surprise to end out the year, here are some final statistics about Mesa's impressive developments in 2017.

  • AVC VDENC Video Encoding Enabled For Intel Broxton & Kabylake

    For those that don't recall, VDENC is a low-power, high-performance video encode engine added originally to Intel Skylake hardware. That aforelinked article covers the big benefits of using VDENC and the patches published earlier this year for enabling this Intel video encode engine on Linux.

EXT4 / F2FS / Btrfs / XFS On Early Linux 4.10 Kernel

Linux

Given all the changes with the Linux 4.10 kernel, including a fair amount of work on file-systems and block / I/O code, here are some fresh benchmarks of the EXT4, F2FS, Btrfs, and XFS file-systems atop a solid-state drive when comparing the early post-RC1 Linux 4.10 kernel benchmarks to that of the 4.6/4.7/4.8/4.9 stable kernels.

For those curious about file-system performance expectations for Linux 4.10 after reading our feature overview or after seeing our recent 4.6/4.7/4.8/4.9 kernel comparison with EXT4/F2FS/Btrfs/XFS, here are fresh results with the Linux 4.10 Git code as of 28 December. All tests were done on the same Intel Core i7 6800K system with Ubuntu 16.10 x86_64. Each file-system was tested on a Toshiba TR150 SATA 3.0 SSD.

  • AMDGPU-PRO vs. RadeonSI/RADV & NVIDIA's Linux Drivers To End 2016

    Last week I published a 31-way Linux graphics card comparison with an assortment of both NVIDIA GeForce and Radeon graphics cards using the latest Linux drivers. I also published a variety of Vulkan benchmarks. In those tests the open-source Radeon driver stack was used given that's what AMD is endorsing these days for Linux gamers with AMDGPU-PRO not even working on all modern Linux distributions. But for those curious how AMDGPU-PRO compares to those big result data-sets, here are those -PRO results to share today.

  • The Wayland Highlights Of 2016

    Wayland much progress in 2016 and arguably the biggest milestone of it shipping by default in Fedora 25 Workstation with the GNOME 3.22 desktop.

    Aside from the GNOME Wayland session premiering as the default on the Fedora desktop this year, many other milestones were achieved. This includes a lot of progress by KDE on their native Wayland support, toolkit support for Wayland continuing to improve, Vulkan working on Wayland, various other compositors advancing their Wayland support, NVIDIA publishing their EGLStreams support for Wayland, new Wayland protocol and Weston features, more Linux desktop programs losing their hard dependencies on X11, and various other efforts.

  • Intel's Beignet Working On More OpenCL 2.0 Support

    It's unfortunate that the Beignet developers weren't able to get OpenCL 2.0 support fully working for Intel graphics hardware by the end of 2016, but nevertheless the project is ongoing and more OCL2 work landed today.

AMDGPU-PRO vs. RadeonSI/RADV & NVIDIA's Linux Drivers To End 2016

Filed under
Graphics/Benchmarks

In this article are AMDGPU-PRO 16.50 (the latest public hybrid driver release) compared to all of last week's data looking at the OpenGL and Vulkan results on the NVIDIA 375.26 and AMDGPU/Radeon+R600g/RadeonSI driver stacks. These tests were done with Ubuntu 16.04.1 LTS for the AMDGPU-PRO 16.50 results due to this hybrid driver not yet officially supporting Ubuntu 16.10, which is the OS used for last week's tests while having upgraded to Linux 4.9 and Mesa 13.1-dev when running the open-source AMD results.

System76 and NVIDIA

  • System76 Has Been Collaborating With NVIDIA Over Linux Driver Fixes

    For helping not only their Ubuntu laptop customers but all NVIDIA Linux users, System76 has recently been working with the green GPU firm over getting more fixes into their proprietary driver.

  • System76 have been working with NVIDIA on Linux driver fixes, a chat with the System76 community manager

    System76, the Linux hardware supplier for laptops, desktops and more has been working with NVIDIA on fixing up their drivers.

    It's good to see more companies get involving in speaking with and working directly with NVIDIA to improve Linux graphics drivers. It's important for our future to have stable drivers as it makes the experience for everyone so much better. Every little issue fixed would hopefully make us look more attractive to people new to Linux too.

    In the NVIDIA 375.26 driver two bug fixes made it in thanks to System76: The screen backlight not coming on after entering idle mode and the driver not detecting when the power source had changed (say between battery and being plugged in).

    They are still working on a bug involving the screen backlight not adjusting properly, which should arrive in a future driver.

    I spoke with their community manager Ryan Sipes about it to see if I could find out a little more.

Given this weekend's release of Darktable 2.2 as a big upgrade to this open-source RAW photo workflow software, here are some fresh benchmarks of NVIDIA GeForce and AMD Radeon graphics cards under Linux when making use of the program's OpenCL support, which did see some improvements during this v2.2 cycle.

  • X.Org Server Development Continues Trending Quite Low

    Development of the X.Org Server by commits and new code barely passed the low amounts achieved in 2015, which in turn is significantly lower -- halved or more -- than just a few years prior.

  • Arcan Display Server Working On X.Org / Wayland Compatibility

    Arcan is the project we first wrote about earlier this year as an open-source display server built atop a game engine and with Lua scripting support. It's been in development for years and progressed a lot this year. Lately the developer has been working on X11 and Wayland compatibility for Arcan.

Ubuntu 16.04.2 LTS Delayed Until February 2, Will Bring Linux 4.8, Newer Mesa

If you've been waiting to upgrade your Ubuntu 16.04 LTS (Xenial Xerus) operating system to the 16.04.2 point release, which should have hit the streets a couple of days ago, you'll have to wait until February 2. We hate to give you guys bad news, but Canonical's engineers are still working hard these days to port all the goodies from the Ubuntu 16.10 (Yakkety Yak) repositories to Ubuntu 16.04 LTS, which is a long-term supported version, until 2019. These include the Linux 4.8 kernel packages and an updated graphics stack based on a newer X.Org Server version and Mesa 3D Graphics Library. Read more
