Linux Gaming Performance With AMD Ryzen 5 2600X / Ryzen 7 2700X

Today the Ryzen+ "Pinnacle Ridge" processors begin shipping and we can now share with you the initial performance results for the Ryzen 5 2600X and Ryzen 7 2700X processors. One of the most common questions I've received about these improved Zen processors since showing them off last week was inquiries/hopes about the Linux gaming performance, so those numbers are first up today followed by other Linux benchmark results forthcoming.

Rise of the Tomb Raider Linux Performance On AMD Radeon GPUs

Yesterday Feral announced that the long-awaited Linux release of Rise of the Tomb Raider would be coming tomorrow and now they have honored that release. Rise of the Tomb Raider is now natively available for Linux and this port is exclusively relying upon the Vulkan graphics API for rendering. Here are our initial benchmarks of Rise of the Tomb Raider on Linux with Radeon GPUs while making use of the Mesa RADV driver.

RadeonSI Now Appears To Support "RX Vega M" With Intel Core CPUs

One of the most common Linux hardware questions I've received dozens of times in the past few weeks alone has been over the support for "RX Vega M" Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs.

Meltdown/PTI Mitigation Impact On BSDs vs. Linux

Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation.

Some DragonFly HAMMER2 / FreeBSD ZFS / Linux EXT4 Benchmarks

With the recent release of DragonFlyBSD 5.2 one of the prominent changes is HAMMER2 now being considered stable for most use-cases. I've been running some benchmarks of this file-system compared to alternatives on other operating systems and have some FreeBSD / Linux reference points to share.

RADV vs. AMDVLK Vulkan Drivers Continue Stiff Performance Battle

With the RADV Mesa Radeon Vulkan driver continuing to be advanced by Valve and other independent developers while AMD continues with open-source code drops of their official AMDVLK Vulkan driver, it's been a friendly open-source Radeon Vulkan driver performance and feature/extension battle since that official AMD Vulkan driver was opened up at the end of last year. With new AMDVLK/XGL/PAL code drops happening about weekly and RADV continuing to receive new feature/performance work every few days, both drivers continue maturing gracefully as shown by our latest performance benchmarks.

Wayland's Weston Begins Switching To Head-Based Output API

Following last week's release of Wayland 1.15 / Weston 4.0, the development gates are once again open for new feature activity to land for Wayland and the reference Weston compositor. Weston has already landed a big patch series for what will likely become Weston 5.0.

P-State/CPUFreq CPU Frequency Scaling Tests For Radeon/NVIDIA Gaming With Linux 4.16

With last week's release of Feral GameMode as a system tool to optimize Linux gaming performance, which at this point just toggles the CPU frequency scaling driver's governor to the "performance" mode, reignited the CPU governor debate, here are some fresh Linux gaming benchmarks. Tests were done with both the CPUFreq and P-State scaling drivers on Linux 4.16 while testing the various governor options and using both AMD Radeon and NVIDIA GeForce graphics cards.

Detailing The Idle Loop Ordering Problem & The Power Improvement In Linux 4.17

Of the many great features/changes for Linux 4.17, one of the most exciting to us is the idle power efficiency and performance-per-Watt improvements on some systems thanks to a rework to the kernel's idle loop handling. Rafael Wysocki and Thomas Ilsche as two of the developers working on this big code change presented on their work today for this CPU idle loop ordering problem and its resolution.

Intel Tremont CPU Support Added To LLVM's Clang Compiler

Earlier this month Intel ISA documentation pointed to a new CPU micro-architecture codenamed "Tremont", we've seen a few kernel patches also referencing Intel Tremont, and now there is Tremont microarchitecture support for LLVM's Clang compiler.

Linux 4.17 Offers Some Promising Power-Savings Improvements

Of the many improvements to be found in the in-development Linux 4.17 kernel -- nicely summarized in our Linux 4.17 feature overview -- one of the features I've been anxious the most to begin benchmarking has been the reported power management improvements. Here are my initial power/performance tests of Linux 4.17 that for some systems is seeing a measurable drop in power usage, even in some cases under load while without sacrificing the performance.

A Look At The Meltdown Performance Impact With DragonFlyBSD 5.2

Besides looking at the HAMMER2 performance in DragonFlyBSD 5.2, another prominent change with this new BSD operating system release is the Spectre and Meltdown mitigations being shipped. In this article are some tests looking at the performance cost of DragonFlyBSD 5.2 for mitigating the Meltdown Intel CPU vulnerability.

The Many Great Features & Changes Coming For The Linux 4.17 Kernel

Linus Torvalds is expected by the end of the day to release Linux 4.17-rc1, thereby marking the end of the two-week merge window that saw a lot of changes and new features land for Linux 4.17. Here is our original feature overview of the changes to be found in this next major release of the Linux kernel, which should premiere as stable by the middle of June.
