Version 5.08.02.027 of the Ryzen Chipset software was released by AMD. The drivers include application support for a “New program support and some new drivers added,” in addition to bug fixes for its many components. The AMD SFH 1.1 driver, AMD PMF-7040Series driver, and the oddly called AMD Interface driver are now included in the package. The SFH, or Sensor Fusion Hub, is a mobile-relevant component that enables the presentation of multiple sensory devices to the OS for use with programs like Windows Hello that require them. The AMD PMF-7040 driver, which is unique to the Ryzen 7040-series “Phoenix” mobile processors, provides Platform Management Framework. It’s unclear what “AMD Interface driver” is.

The Ryzen 7 5800X3D, AMD’s first CPU with 3D V-cache, didn’t experience optimization problems because it was a single-CCD chip. The newest 7900X3D and 7950X3D processors from the firm are dual-CCD processors, one of which has a 64 MB 3D V-cache in addition to the 32 MB on-die L3 cache, and the other of which is a conventional “Zen 4” CCD with only the on-die 32 MB L3 cache. AMD has been employing a driver that aids Windows scheduler in ensuring the appropriate workload is scheduled to the appropriate CCD. The “AMD Interface driver” could act as a backend to a program that most likely provides some sort of control for the 3D V-cache control driver, or it could simply be a Ryzen Master backend. The natural course of action for AMD to take if it needs to give end users control over 3D V-cache application scheduling is to add capabilities to the Ryzen Master app. If a separate front-end application is planned for the project, it is most likely private and intended only for AMD and its ISV partners.
