Can i measure the power consumption of the CPU with Kill-A-Watt?
ive to specifically measure it to a single process (e.g. firefox)
Do you mean only the CPU chip? Or the whole computer (power supply, disk drives, memory etc.). A Kill-A-Watt can measure the power consumption of your computer, but you would need some specialized instrumentation to isolate the power utilization of the CPU chip alone.
An ammeter/wattmeter alone is not going to be able determine what power went to individual processes. You will need to measure the power consumption of the whole computer, then use the operating system process statistics to figure out what percentage of the CPU time was used by firefox. This would be an approximation, as there are other CPU-specific variables such as power-saving modes during idle time etc.
Total Watt for CPU x CPU usage for that particular process (percentage) would give an approximate answer, am i right?
IMO, it cant be done.
