To be honest, Ubuntu likely has nothing to do with it and I find the headline therefore misleading. It's mostly the Linux kernel from how it reads.

Ubuntu 23.10 was run for providing a clean, out-of-the-box look at this common desktop/workstation Linux distribution. Benchmarks of other Linux distributions will come in time in follow-up Phoronix articles. But for the most part the Ubuntu 23.10 performance should be largely similar to that of other modern Linux distributions with the exception of Intel's Clear Linux that takes things to the extreme or those doing non-default tinkering to their Linux installations.

I wonder why they went with a version of Windows 11 Pro instead of Windows 11 Pro for workstations?

Do a Gentoo test with correct compilation parameters! Or just Arch, Fedora or Opensuse Tumbleweed okay.

Let's see Paul Allen's Threadripper performance...

This is the best summary I could come up with:

Going back to the original AMD Ryzen Threadripper processors, Linux has long possessed a performance lead over Microsoft Windows.

With Linux typically being the dominant OS of HPC systems and other large core count servers, the Linux kernel scheduler has coped better than various flavors of Windows when dealing with high core count processors.

Ubuntu 23.10 was run for providing a clean, out-of-the-box look at this common desktop/workstation Linux distribution.

The HP Z6 G5 A for all testing was configured with the Ryzen Threadripper PRO 7995WX at default frequencies, 8 x 16GB DDR5-5200 Hynix RDIMMs, Samsung MZVL21T0HCLR-00BH1 NVMe SSD, NVIDIA GeForce RTX A4000 16GB graphics.

A full review on the HP Z6 G5 A Threadripper workstation will be published in a separate article on Phoronix in early December.

From there the up-to-date Windows 11 Pro Build 22631 (H2'23) was tested against Ubuntu 23.10 with its stable release updates.
