How to figure the capability of a CPU

Hey,
I thought I had this all figured out, when I had a argument with a friend about it :pfff:  ... he says that to figure out the speed of a cpu you need to divide the clock speed by the # of cores... I say that each core runs at the clock speed... so in the case of my Phenom II 965, he says I'd divide my 3.4ghz speed by 4 and thus my speed per core is 850mhz per core... but I say that each core is at 3.4ghz... which is correct?

You are. But with amd's cool and quiet enabled, your core speed will vary with some applications.

Yeah, I dont run c&q... I like the max from my rig... thanks for the quick reply :)  I'll send him a link right now :)

Your friend is full of crap.

If your processor is running at 3.4Ghz, then each core is running at 3.4 as well.

Example: If I have 4 trucks running at 65 miles an hour, that most definitely does NOT equal one running at 260.

What it *does* allow (the computer) to do is to put a different load in each of the four, and deliver them to different places at the same time.

Great thanks guys :)  I appreciate the help, and yeah, I love to laugh at the guys that multiply it by the # of cores :D
