powermon

Displays the CPUs current power consumption

Powermon is a small utility that reads the CPU internal power counters, calculates the current power consumption and displays it together with some nice statistics on an interactive curses interface. All Intel CPUs starting with Sandy Bridge are supported. Older Intel CPUs and CPUs from other vendors don't expose the necessary performance counters. Additionally some server CPUs like those based on Haswell and Broadwell do not provide the necessary data.
