Low-Power Idle States

When the processor is idle, low-power idle states (C-states) are used to save power. More power savings actions are taken for numerically higher C-states (deeper C-states). However, deeper C-states have longer exit and entry latencies. Resolution of C-states occur at the thread, processor IA core, and processor package level.

Idle Power Management Breakdown of the Processor IA Cores

Processor IA core C-states are automatically resolved by the processor. A transition to and from C0 state is required before entering any other C-state.
