Michael Larabel of Phoronix tested the in-development Linux 7.3 kernel against the Linux 7.2 stable kernel on a Framework Laptop 13 Pro equipped with an Intel Core Ultra X9 388H processor. The testing aimed to determine if the new kernel version offered any performance benefits for Intel Panther Lake laptops, following previous improvements in Linux 7.1 and 7.2.
The tests were conducted on an Ubuntu 26.04 LTS installation using Git kernels from the Ubuntu Mainline Kernel PPA. Larabel’s earlier benchmarking of Linux 7.3 on other hardware had already indicated some performance gains, prompting the investigation on the Framework Laptop 13 Pro.
The results showed no significant regressions and some performance improvements in certain areas. The article does not specify which areas saw gains, only that they existed.
