AMD vs Intel volts + temps + frequency question

post #1 of 7
Thread Starter 
I'm just curious. How come AMD processors run at higher volts for the same frequency as intel processors but run at cooler temps? Is it just that the architecture allows it to? What differences allow this to be?

Your comparing apples to oranges, they can't really be compared piece by piece - and the one that starts with A is better

So i guess i need to learn both architectures myself. Anyone have links to good articles on each ones architecture? And I don't see how this could cause a flame war. lol

It's due to power leakage. Different cpu designs and manufacturing processes cause current to leak in tiny amounts from the circuits. This varies from chip to chip. The less leakage a chip has, the less power it requires to operate at a given frequency. However since it's leaking less power that power gets converted to heat, it has to go somewhere.

A cpu that leaks more power requires more current (because it's losing more, like pumping up a tyre with a puncture) to operate at the same frequency as the other cpu, and stays cooler because it's leaking the current and not converting it to heat.


...or something like that! LOL
