Skin temperature-aware power management (STAPM), is a 2014 feature introduced by AMD for its mobile processors that gets the on-die power management logic to take into account not just the processor's own temperatures (measured via on-chip thermal diodes); but also the physical surface temperature of the laptop itself, by reading off temperature probes mounted on the laptop chassis. This ensures that laptops don't get uncomfortably hot for the user, and the processor could do its bit to bring temperatures down. Every desktop APU released by AMD since 2014 has been a case of mobile processor silicon being adapted for the desktop platform by simply disabling certain I/O interfaces and features irrelevant to desktops, such as battery management GPIO, LPDDR memory interfaces, image processing, sensor suite, etc. One such feature is STAPM.
