It would be nice to know what this actually does, to which CPUs, installed in what platform. There is only tenuous correspondence between ACPI C-states and the energy saving features of CPUs, and Intel started diverging from ACPI definitions around the time of Haswell, so a direct comparison is difficult.

Nope. That's AMD's Power Clamping Infrastructure.
