Early Benchmarks: AMD EPYC 9005 Performance & Power Efficiency To Lead Further With Linux 6.13

Phoronix - Wed, 11/13/2024 - 00:10
One of the many changes to look forward to with the upcoming Linux 6.13 kernel cycle is the AMD P-State driver to be used by default with the new EPYC 9005 series processors. While AMD Ryzen CPUs for a while now have been defaulting to the modern AMD P-State driver that makes use of ACPI CPPC platform support for allowing better power efficiency, AMD EPYC CPUs have kept to using the generic ACPI CPUFreq frequency scaling driver. But now AMD engineers have deemed amd_pstate ready for use with EPYC 9005 "Turin" CPUs and will be the default choice moving forward. Here is more information and power/performance benchmarks for this shift while testing using the EPYC 9755 processors.
