Die "Kern"-Frage ;)

Dynamic frequency scaling

According to the ACPI Specs, the C0 working state of a modern-day CPU can be divided into the so called "P"-states (performance states) which allow clock rate reduction and "T"-states (throttling states) which will further throttle down a CPU (but not the actual clock rate) by inserting STPCLK (stop clock) signals and thus omitting duty cycles.

Dürften nur zwei Seiten der gleichen Medaille sein.
