Processor IA Core Power Management

While executing code, Enhanced Intel SpeedStep® Technology and Intel® Speed Shift technology optimizes the processor’s IA core frequency and voltage based on workload. Each frequency and voltage operating point is defined by ACPI as a P-state. When the processor is not executing code, it is idle. A low-power idle state is defined by ACPI as a C-state. In general, deeper power C-states have longer entry and exit latencies.
