AMD P-State EPP Performance With EPYC On Linux 6.3

Among the many new features coming in Linux 6.3 -- including many AMD additions -- is the AMD P-State EPP "Energy Performance Preference" support being merged for modern Ryzen and EPYC systems. AMD P-State EPP can further help tune the performance and power efficiency of AMD Linux systems beyond the existing basic AMD P-State driver support and address some existing deficiencies. Here are some benchmarks of the AMD P-State and ACPI CPUFreq driver configurations benchmarked on an EPYC Milan-X server with the in-development Linux 6.3 kernel.
