One-Line Patch For Intel Meteor Lake Yields Up To 72% Better Performance

Michael Larabel reports via Phoronix: Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance. [...] When looking at the CPU power consumption overall, for the wide variety of workloads tested it was just a slight uptick in power use and thus overall leading to slightly better power efficiency too. See all the data here. So this is quite a nice one-line Linux kernel patch for Meteor Lake and will hopefully be mainlined to the Linux kernel for Linux 6.11 if not squeezing it in as a "fix" for the current Linux 6.10 cycle. It's just too bad though that it took six months after launch for this tuned EPP value to be determined. Fresh benchmarks between Intel Core Ultra and AMD Ryzen on the latest Linux software will be coming up soon on Phoronix.
