Processor Power States

Processor Package and IA Core C-States

  1. PkgC2/C3 are non-architectural: software cannot request to enter these states explicitly. These states are intermediate states between PkgC0 and PkgC6.
  2. There are constraints that prevent the system to go deeper.
  3. The “core state” relates to the core which is in the HIGEST power state in the package (most active).
