Pushing The Intel Panther Lake CPU Performance Further On Linux
We see right away with the "Core Ultra X7 358H - MSI Prestige 14 - Perf" run where the Panther Lake is running in the performance profile, even for "simple" browser workloads there is some added performance uplift for helping pull ahead of AMD Strix Point in raw performance. On a performance-per-Watt basis for this benchmark in Google Chrome, even with the performance profile Panther Lake still had the best performance-per-Watt here.
The increased performance in the Google Chrome benchmarks came with around a 2 Watt increase to the SoC power usage compared to the default balanced mode.
The performance profile on this Intel Panther Lake laptop was more pronounced when it came to the more demanding workloads. With the performance profile activated on the MSI Prestige 14, the Core Ultra X7 358H was now the fastest at compiling the Linux x86_64 kernel with narrowly passing the AMD Ryzen AI 9 HX 370. (Granted, AMD Ryzen AI Max would come out ahead of Panther Lake here.) On a performance-per-Watt basis though the Core Ultra X7 358H now fell behind the AMD Zen 5 Strix Point laptop processors tested, compared to leading in efficiency at the balanced defaults.
Even for a big compile job with building LLVM the performance profile allowed the Core Ultra X7 358H to now outpace the Ryzen AI 9 365 and Ryzen AI 9 HX 370 at those laptop defaults. But those Strix Point SoCs did deliver a better performance-per-Watt than the MSI laptop in its performance mode.
