Methods to calculate power consumption of multi core processor

[vamshi999]

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"

For estimating power need for PSU to power system, there a psu calculator called "eXtreme Power Supply Calculator Lite v2.5" http://www.amazon.com/P3-International-P4400-Electricity-Monitor/dp/B00009MDBU/ref=sr_1_1?ie=UTF8&s=electronics&qid=1260818277&sr=8-1

Although this is estimated power consumption and not actual power you'll be consuming.

i found this link http://www.xbitlabs.com/articles/cpu/display/core2duo-shootout_11.html .... i need something like this.. please correct me if i am wrong... whether i am looking at the right one or nor..

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.

this is the translated page...http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Fwww.testmem.nm.ru%2Fsnm.htm&sl=ru&tl=en ... sorry about the last page..

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.

 

[vamshi999]

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.

can you explain me ...how to do that ?
