Linux 7.0 Showing Some Early Performance Regressions On Intel Panther Lake
Unfortunately, when it came to the Arc B390 Graphics on Linux 7.0, the performance was typically a few percent slower than using Linux 6.19 stable.
I was hopeful of seeing enhanced Panther Lake graphics performance with Linux 7.0 given the ongoing Intel Xe driver enhancements, but at least as it stands right now, the performance on this Core Ultra X7 358H laptop ended up being slower than Linux 7.19.
All of the graphics benchmarks run were slower on Linux 7.0 than Linux 6.19.
For what I had hoped was going to be some nice performance gains on Linux 7.0 with Intel Panther Lake especially for the Arc B390 Graphics ended up being just the opposite. Benchmarks ongoing to see what introduced these regressions in Linux 7.0 Git for Panther Lake and whether other hardware is affected too and the overall extent of these early regressions. At least with the merge window still ongoing and Linux 7.0 stable not debuting until April, there still is time for these regressions to be hopefully addressed prior to release. Linux 7.0 is the kernel expected to power the likes of Fedora Workstation 44 and Ubuntu 26.04 LTS at launch.
