Benchmarking The Experimental Ubuntu x86-64-v3 Build For Greater Performance On Modern CPUs
Benchmarking The Experimental Ubuntu x86-64-v3 Build For Greater Performance On Modern CPUs

One of the exciting innovations currently being explored by Canonical ahead of the Ubuntu 24.04 LTS release is an x86-64-v3 build of the OS / packages. The x86-64-v3 micro-architecture feature level makes AVX/AVX2 support assumed by default as well as other modern x86_64 ISA features typically common of AMD and Intel processors the past number of years (with exceptions). Canonical's determination around what to do with a possible complementary Ubuntu x86-64-v3 build/archive is still being determined but they had released an experimental Ubuntu 23.04 based build that I decided to take for some benchmarking.

Ubuntu 23.10 Showing Nice Performance Improvements On Ampere Altra Max

Gigabyte (Giga Computing) recently sent over their G242-P36 HPC/AI Arm server platform built for Ampere Altra and Ampere Altra Max processors. This 2U server platform can accommodate up to four graphics cards or a mix of GPUs and DPUs if so desired, for maxing out the AI possibilities on Arm. I'll have up a full review on the G242-P36 soon while in this article is a look at the direction of the Ubuntu Server Arm performance from Ubuntu 22.04 LTS to now with Ubuntu 23.10 ahead of the important Ubuntu 24.04 LTS cycle.

Intel Continues To Demonstrate The Importance Of Software Optimizations: Clear Linux + Xeon Max Benchmarks
Intel Continues To Demonstrate The Importance Of Software Optimizations: Clear Linux + Xeon Max Benchmarks

While the recently released Ubuntu 23.10 is bringing some performance improvements to Intel Xeon Max / Sapphire Rapids, Ubuntu Linux still isn't delivering the best possible out-of-the-box server performance. For that Intel continues to show the importance of software optimizations with the likes of their in-house Clear Linux platform as well as the likes of CentOS Stream having more sensible defaults. Here is a look at the Intel Xeon Max 9480 performance across Ubuntu 22.04 LTS, Ubuntu 23.10, CentOS Stream 9, Fedora Server 39, and Clear Linux 40130.

Benchmarks: AMD Ryzen 7000 Series Performance Boosted With Ubuntu 23.10
Benchmarks: AMD Ryzen 7000 Series Performance Boosted With Ubuntu 23.10

With Ubuntu 23.10 due for release on Thursday, I've been benchmarking a number of systems to look at the Ubuntu 23.10 performance against prior releases like Ubuntu 23.04 and Ubuntu 22.04 LTS. Besides the open-source graphics driver performance for Intel and AMD Radeon graphics always being a stand-out improvement, one area that is particularly exciting with Ubuntu 23.10 is for those with newer AMD processors where there are some nice performance gains to find with this new Ubuntu Linux release. Here are side-by-side benchmarks of an AMD Ryzen 9 7950X desktop along with an Intel Core i9 13900K desktop while testing Ubuntu 22.04.3 LTS / Ubuntu 23.04 / Ubuntu 23.10.

AMD Ryzen 9 7950X "Zen 4" Rocks On Intel's Clear Linux
AMD Ryzen 9 7950X "Zen 4" Rocks On Intel's Clear Linux

This shouldn't be too surprising to long-time Phoronix readers, but Intel's performance-optimized Clear Linux operating system is yielding great performance with AMD Ryzen 7000 series "Zen 4" processors. Intel's Clear Linux has long shipped HWCAPS support and tuning for AVX-512 and the like to be able to provide optimized libraries when running on their own AVX-512 processors. But with AMD now joining the AVX-512 party -- and Zen 4's AVX-512 implementation performing great -- Intel's Clear Linux distribution is showing leading performance numbers on these new AMD desktop processors.

Windows 11 vs. Ubuntu Linux Performance Is Very Close On The AMD Ryzen 9 7950X

One of the leading test requests at Phoronix around my AMD Zen 4 Linux benchmarking has been some side-by-side comparisons against Microsoft Windows 11. While older, high core count AMD systems have particularly performed very well under Linux against Windows, with new hardware there is sometimes hiccups and various limitations with the at-launch support especially on the open-source Linux side. So for your viewing pleasure today are some initial AMD Ryzen 9 7950X benchmarks under Microsoft Windows 11 22H2 up against Ubuntu 22.04.1 LTS and a near-final development snapshot of the upcoming Ubuntu 22.10.
