Why do some VAIO computers show 2 types of clock frequencies in System Information?

    The System Information tab in Sony Notebook Setup shows 2 kinds of clock frequencies.

    The types of VAIO computers that show 2 types of clock frequencies are:
    1. CPUs that have equipped with the Intel® SpeedStep technology
    2. CPUs that are driven with low voltage

    These types of CPU will have 2 different clock frequencies.
    This is because one clock is for running in the AC operation and the other is for running in the battery operation.
