It all starts with precision monitoring and measurements down to Milliseconds. As example Intel has made a tool to monitor the Intel CPU parameters. It displays the Power the Frequency and the Temp. The Power usage and the Temperature are products of the Frequency (the speed), or the amount of data processed. The sampling rate is Milliseconds and the ...
