AMD is preparing to introduce a new specification called CPPC HighestFreq for its modern Ryzen processors. This update aims to eliminate the need for the operating system to estimate or interpolate CPU frequencies. Instead, the firmware will report the true maximum boost frequencies directly to the OS.
Driver prepared for Linux AMD P-State support and ACPI 6.7
The feature relies on Collaborative Processor Performance Control, a technology already used by AMD Ryzen CPUs. The change is prepared for the Linux AMD P-State driver to support this new reporting method. It is expected to become part of the upcoming ACPI 6.7 specification.
According to Wccftech, this update could improve thread scheduling efficiency and responsiveness. The HighestFreq feature allows the operating system to identify the best-performing CPU cores for demanding tasks. The scheduler will prioritize the fastest cores available rather than relying on estimated values.
This technical specification update impacts both hardware and software domains. It directly affects CPUs by providing more accurate performance data and improves software driver support. The changes also have significant implications for gaming performance through better core prioritization.
Wccftech notes that the feature is expected to be included in the upcoming ACPI 6.7 specification. The source uses conditional language such as could improve, indicating that these performance improvements are potential rather than confirmed. AMD has not confirmed the launch window for this specification update.
