Igalia Aligns Latest Patches For Giving Intel's Mesa Driver OpenGL 4.6

Igalia developers have been very involved with the Intel open-source developers on getting the long-awaited OpenGL 4.6 support into the "i965" Mesa driver. As has been the case for a while, out-of-tree patches can allow this to happen but with the Mesa 18.2 branching soon, it doesn't look like this will materialize ahead of this next release.

Vulkan vs. OpenGL Performance For Linux Games

It has been a while since last publishing some Linux GPU driver benchmarks focused explicitly on the OpenGL vs. Vulkan performance, but that changed today with a fresh look at the performance between these two Khronos graphics APIs when tested with AMD and NVIDIA hardware on the latest RadeonSI/RADV and NVIDIA Linux graphics drivers.

GCC 8/9 Land Fix For "-march=native" Tuning On Modern Intel CPUs

The other day we reported on a GCC 8 regression where Skylake and newer CPUs with "-march=native" haven't been performance as optimally as they should be. Fortunately, that patch was quickly landed into the GCC SVN/Git code for GCC 9 as well as back-ported to GCC 8.

Windows Server 2016 vs. FreeBSD 11.2 vs. 8 Linux Distributions Performance

Given the recent releases of FreeBSD 11.2, Scientific Linux 6.10, openSUSE Leap 15, and other distribution updates in the past quarter, here are some fresh benchmarks of eight different Linux distributions compared to FreeBSD 11.2 and Microsoft Windows Server 2016. The tested Linux platforms for this go-around were CentOS 7.5, Clear Linux 23610, Debian 9.4, Fedora Server 28, openSUSE leap 15.0, Scientific Linux 6.10, Scientific Linux 7.5, and Ubuntu 18.04 LTS.

More Mutter Performance Tuning Work Landing For GNOME 3.30

GNOME 3.30 is looking like Mutter will be quite fit with the ability to remove its dependence on X11 code and various performance tuning optimizations. On top of already landed performance work in recent months, more optimizations have just landed and it looks like more could still be on the way.

Vega 20 Support Added To RadeonSI Gallium3D Driver

With the upcoming Linux 4.18 kernel release due out in August there is the AMDGPU kernel driver support for Vega 20, the yet-to-be-released Vega GPU said to be the 7nm part launching later this year in Radeon Instinct products and featuring 32GB of HBM2 and adding some new deep learning instructions. Now the RadeonSI Gallium3D user-space driver for OpenGL within Mesa has Vega 20 support.

GCC 8 Hasn't Been Performing As Fast As It Should For Skylake With "-march=native"

It turns out that when using GCC 8 since April (or GCC 9 development code) if running on Intel Skylake (or newer architectures like the yet-to-be-out Cannonlake or Icelake) and compile your code with the "-march=native" flag for what should tune for your CPU microarchitecture's full capabilities, that hasn't entirely been the case. A fix is en route that can correct the performance by as much as 60%.

The NVIDIA/AMD Linux GPU Gaming Benchmarks & Performance-Per-Dollar For July 2018

In part with GPU demand by crypto-currency miners waning a bit, NVIDIA GeForce and AMD Radeon graphics card availability at retailers has been improving in recent weeks as well as seeing less inflated prices than just recently had been the case. Given the better availability and stabilizing prices, here is a fresh look of the current line-up of GeForce and Radeon graphics cards under Ubuntu Linux using the newest AMD/NVIDIA drivers and also providing performance-per-dollar metrics given current retail prices.
