AMD Finally Releases Overdue Linux CPPC Driver

As reported by Phoronix, AMD’s Zen 3 architecture is getting support for the ACPI CPPC

As reported by Phoronix, AMD’s Zen 3 architecture is getting support for the ACPI CPPC driver designed for Linux-based operating systems. The Collaborative Processor Performance Control driver allows Linux to see which cores have the highest boosting potential in a Ryzen CPU and target the highest boosting cores for single- or lightly-threaded workloads, a feature that has been supported in Windows since the launch of the Zen 2 processors. Additionally, the ACPI driver will improve Linux’s support of Ryzen power states, allowing for better power consumption and performance. However, the new drivers are currently only for Zen 3, with Zen 2 support coming down the road.

This is much better than the current generic CPUFreq driver built into Linux, which, as the name states, is generic and isn’t fully optimized for AMD processors.
