The AMD Ryzen 9 5900X and Ryzen 9 5950X are hands-down incredible winners. While processor company marketing claims are sometimes dubious and not necessarily relevant to Linux users and their open-source workloads/software, after testing the Ryzen 9 5900X and 5950X the past several weeks the performance has been incredibly compelling with significant single and multi-threaded performance uplift over Zen 2 and easily thrashing Intel's current desktop offerings with over 200 benchmarks conducted for launch-day.

After just publishing the results of 200+ Linux benchmarks under many diverse workloads for the Ryzen 9 5900X and Ryzen 9 5950X we see the 16~20% performance lift is very real and very broad from obscure open-source niche software through high profile programs... What about the Linux gaming performance? This article offers a first look at the Ryzen 9 5900X/5950X Linux gaming performance compared to Zen 2 and the Core i9 10900K while being the first of several Linux gaming performance articles coming out this month.

Cincoze is a brand we previously haven't tested at Phoronix but is a Chinese manufacturer of embedded computers. The company's recently introduced GM-1000 is advertised as a "Machine Vision Embedded Computer" geared for a variety of industrial applications in being constructed within a well engineered aluminum enclosure that is fan-less thanks to an array of heatpipes and chassis serving as a heatsink while offering MXM-based GPU expansion and a total system power budget of up to 360 Watts.

Given Intel's very fresh Tiger Lake platform, our latest benchmarking with the Core i7-1165G7 within the Dell XPS 9310 is seeing if running the in-development Linux 5.10 kernel means any performance or power changes for this latest-generation Intel mobile CPU with Xe/Gen12 graphics...

While Qt 6.0 is aiming to ship in December there are many open bugs against the Qt code-base. Given the increasing number of P1 priority bug reports that are the highest besides the "P0" build breakage bug reports, developers are discussing what to do with these bugs and the merits of their current priority classifications...

We haven't heard much of traditional Linux gaming on any ARM-powered Qualcomm notebooks as it would rely on the likes of Hangover for running Windows x86_64 games on ARM, but the Turnip Vulkan driver within Mesa has a necessary feature for now being able to run DXVK with the Direct3D 10_1 (v10.1) feature level...

The Linux x86_64 micro-architecture feature levels have taken shape this year for different feature/performance levels based on a CPU's capabilities. Both LLVM Clang 12 and GCC 11 are ready to go in offering the new x86-64-v2, x86-64-v3, and x86-64-v4 targets...

September marked a decade since the OpenIndiana project was announced for continuing on with the OpenSolaris code-base (and ultimately based on Illumos) in being born out of the justified and proven accurate concerns when Oracle acquired Sun Microsystems. OpenIndiana Hipster 2020.10 was released this weekend as the newest version of this open-source operating system...

Another month in the books, another month closer to the end of the dreadful 2020.

The content ranged from the continuous Linux kernel advancements to exciting hardware announcements...

The Wine program for running Windows games/applications on Linux and other platforms can run on a number of different architectures, but Wine doesn't handle the emulation of running Windows x86/x64 binaries on other architectures like 64-bit ARM or PowerPC. But that's what the Wine-based Hangover is about with currently allowing those conventional Windows binaries to run on AArch64 (ARM64) and 64-bit POWER too...

With this month's Ubuntu/Debian-based Linux Mint development news there are two items worth calling attention to...

Laptop vendors recently disclosed "Xe MAX" graphics as discrete Intel graphics set to appear within laptops in the coming weeks. That announcement was a bit unexpected and Intel did not brief the media in advance while today -- in an unusual announcement for a Saturday (Intel says it's timed for system availability, seemingly first in China) -- the company is formally announcing Iris Xe MAX.

This week brought the release of AMD's ROCm 3.9 as their open-source compute stack for Radeon GPUs. With ROCm 3.9 the AOMP work for LLVM/Clang-based compiler with OpenMP offload capabilities to Radeon GPUs was integrated. AOMP though is still advancing independently of the ROCm releases with Friday night marking the release of AOMP 11.11...
