I was just curious as to what ya'll thought. What is the biggest heat producing component of a cpu? Or is it just a combination of everything. I was just reading this here <A HREF="http://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,... " target="_new">http://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,... </A> and I see that, yes, these arent super high clock speeds, but even 14w for 1.4ghz seems pretty low to me. How would they have gotten the power usage down so low? I noticed that the other specs were almost identical to a Thorton/Palamino core. 266fsb 128/256 L1/L2 cache. Would one of these even need a heat sink? Is this pehaps something we might be seeing in dual-triple-quad cored processors, what I mean is, a bunch of low power cores that add up to quite a wallop?

That is [-peep-] awesome. I'd buy one right now, if I could.

In general, High Speed I/O switching causes highest power dissipation on a chip, the more there is, the more dominant, so external memory is goona require this, High internal memory is thus better, but manufacturers utilise this to add speed, which it's self requires more current to operate at peak frequence, so add heat. Also high memory count IC's are bigger, less chips per wafer, lower yield, cost more money, that's why laptops cost a lot for less...

probably because the p-m's would put them to shame. :wink:
