The author threw lots of benchmarks at all four operating systems. Windows 11 Pro, Ubuntu 22.04 LTS, Ubuntu 22.04 LTS after installation of the Linux 5.18 Stable kernel, and Intel's Clear Linux 36580 were tested in the benchmarks. It is powered by an Intel Core i9 12900K processor at default speeds, an ASUS ROG STRIX z690-E gaming WiFI motherboard, 2x 16 Gigabytes of DDR5-6000 memory, a 500 Gigabyte Western Digital Black SN850 NVMe SSD, and a Radeon RX 6800 XT graphics card. The same computer system was used in the benchmark. The Linux kernel received performance fixes for Alder Lake in the meantime, and the author decided to run the benchmarks again to see if the situation has improved. Windows 11 outperformed Linux in the initial test back in November 2021, and this came down to missing Linux kernel patches according to the author.

The site performed the test several times since the release of Intel's Core i9 12900K Alder Lake processor.
