Intel Alder Lake processor users running Ubuntu 22.04 LTS “Jammy Jellyfish” based systems will continue to suffer performance compromises unless they update their Linux kernel to a newer version. Linux-based news site Phoronix has released a series of benchmark results to show the difference.

Ubuntu’s latest LTS issue is rooted in the Linux 5.15 kernel. But stable 5.16 kernel builds have been available since January and 5.17 came out a few weeks ago. The new kernels contain lots of hardware optimizations. At this point, the potential power of the 12th Generation Alder Lake processors has also emerged.

Legacy Linux kernels mainly fail to use Alder Lake’s hybrid architecture efficiently. Here are some of the important tesdollars made:

1 – 3

Comparisons Intel Core i9 12900K processor with 2 x 16GB DDR5-5400 memory modules, ASUS ROG Strix Z690-E Gaming Wi-Fi motherboard and 2TB WD Black Made on SN850 NVMe SSD. The same system was used only for comparison with various Linux kernels.

The chart above shows the geometric mean over all tesdollarser run. As a result, there is an improvement of about 14% for the i9-12900K when upgrading from the stock kernel of Ubuntu 22.04 to later versions.
