The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.47 GHz (asserted by call to hardware) boost state support: Supported: no Active: no 2000 MHz max turbo 2 active cores 2000 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1 C1E C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 3379 Duration: 50384 C1: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 11339 Duration: 1475234 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 20901 Duration: 2568421 C3: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 489254 Duration: 1373523942
