Unexpected Performance Regressions on Intel Panther Lake with Linux 7.0

Early performance tests on Linux 7.0 reveal an unexpected picture for the new Intel Core Ultra Series 3 "Panther Lake" processors. Contrary to expectations of improvement, preliminary benchmarks indicate a performance regression.

These results emerged during the merge window of Linux 7.0, a period in which it was hoped to capitalize on the progress of Intel Xe graphics drivers and general kernel optimizations. The 7.0-rc1 release is expected soon, and it is hoped that further testing will clarify the nature of these regressions.

General Context

It is important to note that preliminary results may not reflect the final performance that will be obtained with stable versions of Linux 7.0. The kernel development process is iterative, and performance can vary significantly between different phases. Further optimizations and bug fixes may lead to improvements in the future.
