John,

what is so different about the AMD chip that it can take the heat?

Semiconductors generally have a relationship between temperature and speed, where the higher the temperature, the lower the speed at which the part will function correctly.

Normally, parts are tested at 80-90C because that is the upper limit of temperatures found in normal operating environments. All PIII parts which run below 933MHz are rated up to at least 80C.

Intel is unable to manufacture PIII's that run at 1GHz and 80C, so they lowered the operating temperature to 60C. This is a very questionable practice, to say the least.

If AMD chose to lower their standards to 60C, they could be shipping parts at 1.4GHz right now. I hope the company has the integrity not to do that, however.
