There have been 1,071 Linux hardware reviews and benchmark articles on Phoronix for operating systems. Separately, check out our news section for related product news.

With Canonical engineers again experimenting with x86_64-v3 package builds for Ubuntu Linux using an "amd64v3" archive for the current Ubuntu 26.10 development, I decided to see how these latest amd64v3 packages comparing to their conventional Ubuntu 26.10 amd64 packages.

Earlier this week I ran benchmarks of different CachyOS Linux kernel flavors that proved interesting from the performance overhead of their hardened kernel build to various other interesting performancr takeaways. One kernel flavor I hadn't tested though was their build with the BORE scheduler. Given the interest and feedback from Phoronix readers, here is an article focused on looking at the performance of the BORE scheduler for the Linux kernel on CachyOS.

CachyOS ships with a good Linux kernel configuration by default balancing the different features as well as performance. But they also ship a variety of other kernel builds for those preferring a more leading-edge kernel or the current LTS series, a hardened kernel configuration, and more. In this article are some fresh benchmarks of the Arch Linux based CachyOS Linux distribution with some of its main kernel flavors.

The new System76 Thelio Major powered by the AMD Ryzen Threadripper 9000 series and optionally with the Radeon AI PRO R9700 graphics card for an all-open-source AMD Linux stack is a mighty powerful workstation. If desiring even more compute potential out of this high-end desktop/workstation, CachyOS works pretty darn well on this new system with lofty leads over upstream Arch Linux as well as Ubuntu 26.04 LTS and the stock Pop!_OS 24.04 distribution.

Last month with the new AMD Zen 5 "Dual Edition" 3D V-Cache CPU, the AMD Ryzen 9 9950X3D2 Dual Edition showed great performance on Linux across a range of workloads. Curious if the operating system was playing into the greater benefit of Ryzen 9 9950X3D2 versus just the workloads tested, this article is looking at both the AMD Ryzen 9 9950X3D and Ryzen 9 9950X3D2 on Microsoft Windows 11 and Ubuntu 26.04 LTS Linux across a range of native benchmarks.

It's not too entirely surprising given the aggressive stance that the CachyOS Linux distribution has taken on out-of-the-box performance, but for those curious, it continues largely leading over the newly-released Ubuntu 26.04 LTS and Fedora Workstation 44 distributions for the leading performance on modern hardware.

Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.

The past few weeks I have been testing out the new HP Z6 G5 A workstation desktop PC. It's a beast in being powered by the AMD Ryzen Threadripper PRO 9975WX, eight channels of DDR5-5600 memory, and paired with a NVIDIA RTX PRO 6000 Max-Q workstation graphics card. The full review on the HP Z6 G5 A workstation will be published on Phoronix in the next week or so but given the timing and that it shipped with WIndows 11 Pro, here is a look at how Windows 11 Pro is competing against the newly-released Ubuntu 26.04 LTS in creator/workstation workloads.

As part of my ongoing testing around the upcoming Ubuntu 26.04 release I have been running a lot of benchmarks. After recently showing some nice performance gains for AMD Ryzen AI Max "Strix Halo" with Ubuntu 26.04, several Phoronix readers inquired about any performance uplift from the more modest but still powerful Strix Point laptops like the popular Ryzen AI 9 HX 370 SKU. Here are benchmarks showing the performance of Ubuntu 26.04 in its near final state compared to Ubuntu 24.04.4 LTS with its HWE stack on an ASUS Zenbook S16.

Last week I provided benchmarks to quantify how the AMD Strix Halo graphics performance has evolved since launch one year ago, in today's article is a look at how the Zen 5 CPU performance with the flagship Ryzen AI Max+ 395 has evolved under Linux in the year since these exciting APUs began making their way to high-end laptops and desktops. Complementing the nice Radeon 8060S performance gains are also some nice CPU performance benefits quantified when using Ubuntu 26.04.

Most of my Intel Panther Lake benchmarking over the past two months for the new Core Ultra Series 3 hardware has been done with Ubuntu Linux given the pervasiveness of it, especially in the corporate/enterprise space. But for those looking at achieving even greater out-of-the-box Linux performance on Intel Panther Lake, the Arch Linux based CachyOS does a pretty fine job at further advancing the performance.

With the Ubuntu 26.04 LTS release due out in three weeks, I have been re-testing a number of different devices on this newest Ubuntu release. One of the most significant improvements to note was when running the Framework Desktop with Ryzen AI Max "Strix Halo" and quantifying the performance gains of the Radeon 8060S Graphics since launch last year. Here's a look at how the Vulkan and OpenGL performance has evolved for the Ryzen AI Max+ 395 since its launch last year in going from Ubuntu 25.04 to Ubuntu 26.04.

While having the new System76 Thelio Mira in the lab I ran some benchmarks of Ubuntu 24.04 LTS vs. 26.04 development on that AMD Ryzen 9000 series powered desktop. Those results were interesting for how the Ubuntu performance has changed over the past two years, but even if drilling down to just the past six months there have been some nice gains on the AMD Zen 5 desktop. In this article is a look at how Ubuntu 26.04 in its near-final state is performing relative to Ubuntu 25.10 with this Ryzen 9 9950X desktop.

While having the new System76 Thelio Mira desktop in the lab, I took the opportunity to run some benchmarks to see how Pop!_OS 24.04 is currently performing relative to Ubuntu 24.04 LTS for which it is based as well as looking ahead at how Ubuntu 26.04 LTS in its current near-final development form is looking on the same hardware.

Since last week's Fedora 44 Beta release I have been testing out this upcoming Fedora Linux version on a few systems in the lab, most notably with the Framework Desktop powered by the powerful AMD Ryzen AI Max+ 395 "Strix Halo". Fedora Workstation 44 Beta has been looking nice and running stable albeit in some instances seeing lower performance at this point than Fedora Workstation 43 but overall in good shape.

Earlier this month I posted benchmarks of the Loongson 3B6000 for this 12-core / 24-thread LoongArch Chinese CPU with DDR4 ECC memory. Those initial benchmarks were done with Debian LoongArch64 while since then I've shifted over to using Arch Linux on LoongArch.

Last week I began publishing the many exciting Panther Lake benchmarks under Linux from the interesting CPU performance and efficiency to the much anticipated Xe3 graphics with the Intel Arc B390 graphics. Up today is a look at how the out-of-the-box performance for the Intel Core Ultra X7 358H compares under Microsoft Windows 11 and the current Ubuntu Linux 26.04 development state.

There still are several months to go until the official Ubuntu 26.04 LTS release -- including one month until the feature freeze and the future Linux 6.20~7.0 kernel is expected to land too before the latter kernel freeze in early April. But for those curious how Ubuntu 26.04 is looking so far for servers, here are some very early benchmarks of it on AMD EPYC 9005 "Turin" in its present development state. The main motivation here for this early look was stemming from the recent rolling-release CachyOS benchmarks on AMD EPYC and wanting to see how it goes up against the current development state of Ubuntu Linux.

One of the more interesting announcements over the holiday period thus far is that moving into 2026, CachyOS is looking to develop a server edition for their Arch Linux based operating system. CachyOS has garnered quite a following among Linux enthusiasts and gamers for its competitive out-of-the-box performance, employing some of the optimizations by Intel's now defunct Clear Linux distribution, and pulling in all of the goodness from upstream Arch Linux. It will be very interesting to see how CachyOS Server Edition takes shape and whether it will develop a foothold in any prominent enterprise environments. While CachyOS Server Edition isn't yet released and still in its early stages, over the holidays I decided to see how CachyOS in its current form currently looks for AMD EPYC servers.

Given the recent release of FreeBSD 15, I started off my testing in looking at how FreeBSD 15.0 improves performance versus FreeBSD 14.3. Now it's onto the next important question: how is FreeBSD 15.0 performing relative to Linux on servers? Here are some benchmarks exploring that topic today.

This week brought the official release of FreeBSD 15.0 as the latest major update to this BSD operating system. In being eager to test out this new FreeBSD release, for this first round of FreeBSD 15.0 benchmarking is seeing how it compares to the former FreeBSD 14.3 release on a Supermicro + AMD EPYC Turin server.

Last week when delivering some CachyOS benchmarks against Fedora 43 and Ubuntu 25.10 on the Framework Desktop with AMD Ryzen AI Max+, a few Phoronix readers wrote in with the question or belief that openSUSE Tumbleweed would better perform against CachyOS given the distribution's select x86_64-v3 packages and other advantages. As it's been a while since running any benchmarks of the rolling-release openSUSE Tumbleweed, here are those benchmarks now in the mix for seeing how the performance compares.

With Intel having sunset Clear Linux, when it comes to aggressive out-of-the-box Linux performance there is the Arch Linux based CachyOS as the leading contender. Given the recent releases of Ubuntu 25.10 and Fedora Workstation 43, if you are curious about the out-of-the-box performance here are some fresh benchmarks of all three using the Framework Desktop.

Yesterday Canonical announced architecture variants for Ubuntu Linux with Ubuntu 25.10 seeing the introduction of "amd64v3" packages that are built for the x86_64-v3 micro-architecture feature level to assume AVX/AVX2 and other newer CPU ISA features found since Intel Haswell and AMD Excavator processors. Eager to run some initial tests, here is a first look at the Ubuntu 25.10 amd64v3 performance for desktop workloads.

This week marks fifteen months since AMD Strix Point laptops began shipping. Back at the end of July 2024 the Linux performance and support was already in good shape while since then the Linux performance has only evolved even more to make these AMD Zen 5 laptops perform even better. Here is a fresh look at how the performance has evolved since launch day and the added gains when moving to the recently released Ubuntu 25.10 and some performance advantages too if moving to the in-development Linux 6.18 kernel.

For those wondering how the AMD 3D V-Cache performance with the Ryzen 9 9950X3D is looking on Linux relative to Microsoft Windows, a few weeks back I carried out some comparison benchmarks of Windows 11 25H2 against Ubuntu Linux both the Ubuntu 24.04.3 LTS release and an Ubuntu 25.10 development build using both the AMD Ryzen 9 9950X and Ryzen 9 9950X3D processors.

With the recent release of Ubuntu 25.10 we have seen some nice performance improvements on the likes of AMD Zen 5 and Intel Lunar Lake compared to prior Ubuntu releases. But what about ARM? In this article is a look at the Ampere Altra performance between Ubuntu 25.04 and Ubuntu 25.10 using the popular System76 Thelio Astra workstation.

Last week System76 released the Pop!_OS 24.04 beta along with the beta COSMIC desktop. This long overdue update to Pop!_OS re-bases against the Ubuntu 24.04 LTS base while featuring their modern, Rust-based desktop environment. For those curious I ran some benchmarks of Pop!_OS 24.04 beta compared to the current Pop!_OS 22.04 stable release.

Ubuntu 25.10 is looking quite nice in the performance department ahead of its official release later this week. On various systems tested thus far, Ubuntu 25.10 is delivering nice gains over Ubuntu 25.04 and compared to the current Ubuntu 24.04 LTS. The latest Ubuntu 25.10 benchmarking at Phoronix is looking at the Intel Core Ultra Lunar Lake performance using the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.

Fedora 43 Beta is releasing today as we work toward the official release in either late October or early November. I have been testing out the Fedora Workstation 43 Beta candidate to great success on the AMD Ryzen AI Max+ "Strix Halo" powered Framework Desktop. Here are some benchmarks of Fedora Workstation 42 compared to the Fedora Workstation 43 Beta.
