How To Check CPU Core Frequency

Version 2

    This is a guide for running performance benchmarks.
    Before we start, make sure the CPU core frequency is close to maximum.

    To see if all CPU cores are running on the same frequency and each core running on maximum supported capacity, run:

    # cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq

    3300000

    3300000

    3300000

    3300000

    3300000

    ...

     

    To view current CPU frequency (for comparison)

    # cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

    1199975

    1200256

    1199975

    1200115

    1200677

    1199694

     

    If the CPU frequency is not at maximum capacity, make sure the settings are turned to max performance in the BIOS.
