Despite Alder Lake optimizations, Windows 11 is struggling to get ahead of Ubuntu/Linux.

Back at the Architecture Day 2021 event, when Intel shared details of the underlying design of its Alder Lake CPU architecture, the firm said Windows 11 is optimized to best take advantage of Alder Lake’s hybrid architecture and new Thread Director technology. it helps to schedule Windows 11 tasks.

A benchmark test last November did show Intel’s 12th generation chips slightly ahead of Ubuntu and the Linux 5.15 kernel. With the subsequent release of Linux 5.16, Alder Lake performance was not as stable as it was with Windows 11.

However, with the recent Ubuntu 22.04 LTS with Linux kernel version 5.18, things weren’t so easy for Windows 11. Despite Thread Director optimizations, Microsoft’s OS failed in a recent July test.

Today, Phoronix tested the Alder Lake-P Core i7-1280P to see how the Big-Bigger mobile architecture performs on Windows 11 versus Clear Linux and Ubuntu. The test bench consisted of the following components:

MSI MS-14C6 Prestige 14 Evo

  • Core i7-1280P
  • 16 GB RAM
  • 1TB Micron 3400 NVMe SSD
  • Ubuntu 22.04 LTS with Linux 5.18
  • Purge Linux 36580 (Linux kernel v5.18)

All in all, it’s a mixed bag of performance. We start with ParaView , in which case Windows 11 performs much better than Clear Linux and Ubuntu.

However, in Java 2D rendering tests, both Ubuntu 22.04 and Clear Linux show a very significant performance advantage over Windows 11.

In the CanvasMark test of the Google Chrome Selenium browser, Ubuntu is almost twice as fast as Windows 11, and Clear Linux is even faster.

The combined geometric mean of all benchmark results shows that Windows 11 is only 1.5% faster than Ubuntu 22.04, which is a good indicator of the fact that the new Linux kernel is starting to include Alder Lake optimizations. It also bodes well for the upcoming Raptor Lake.
