TL;DR: AMD is introducing a new CPPC-based "Highest Frequency" feature to improve CPU scheduling accuracy on Windows 11 and Linux by exposing actual maximum boost clocks directly to the OS. This enhancement aims to optimize workload assignment, boost prediction, and CPU capacity calculations, with support planned in ACPI 6.7 and future AMD processors.
