Hi.. iam looking for a method or device or software which can calculate the power consumption of a multicore processor... and if a device or software exists.. how much would it cost me.... please do reply as soon as possible..
thank you ...

There not really a device or software program that can measure power consumption to a single item (like a cpu) for the general market that im aware of. There is however a way to see your overall system power consumption called a "kill a watt"

Well first i have heard of a program that can measure power consumption to a single item. although the web site that they lead you to that has the program is in a language i cant read.... So i cant say how well it works.

I also would like to know how it works. As far as I know, there are no sensors that such a utility could monitor to calculate power consumption.

I use a clamp-on ammeter to measure the current flowing through the yellow wires (12 volt) in the CPU power cable. Times 12 volts gives me watts into the motherboard power regulator.

I usually just read the spec sheet for the particular processor, and pretty much just go with that. :)

it seems there are some specific methods to calculate the power consumed by a multiprocessor..... the power consumption varies with the execution of same program in different ways...

Or I just estimate 10 amps (120 watts) for an OC'd quad core CPU.
