Linux 7.3 Delivering Some Performance Gains On Intel Panther Lake / Framework Laptop 13 Pro
Linux 7.1 brought some performance improvements for Intel Core Ultra Series 3 "Panther Lake", Linux 7.2 enhanced the performance for the integrated Arc B390 Xe3 graphics, and now for the in-development Linux 7.3 kernel are various performance improvements at large. Today's article is looking at the performance of the in-development Linux 7.3 kernel compared to Linux 7.2 stable using the Core Ultra X9 388H within the Framework Laptop 13 Pro.
My earlier Linux 7.3 benchmarking on other hardware found some performance gains and paired with all the new Linux 7.3 features, I was curious to see if there was any performance benefit of this upcoming kernel for the popular Intel Panther Lake laptops.
With the Framework Laptop 13 Pro review unit with flagship Intel Core Ultra X9 388H, on an Ubuntu 26.04 LTS installation I compared the Linux 7.2 and Linux 7.3 Git kernel performance from the Ubuntu Mainline Kernel PPA. Fortunately, no scary regressions but some performance wins in a few areas.
