AMD Ryzen 9 9950X vs. 9950X3D On Windows 11 & Ubuntu Linux

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.
