Actually, in most AMD CPUs you have the naked die underside looking at
you. A number of people had to find out how brittle silicon is the hard
way (chipped edges at best, dead die at worst).

No idea. I'm told recent AMDs have built-in thermal protection, but no
motherboard so far (?) supports that. Given that their power density is
currently higher than Intel, this means instant thermal death if your heat
sink grows a gap, or a slow death if your fan fails or the fan connector

Nope, that's empirical observation from the trenches. Thermal design for
AMDs is far more critical than Intel. For time being, I'm rather fond of
AMDs, and this won't deter me from building my viz/number crunch box on
AMD. Meanwhile, my current box is a 700 MHz Intel Celeron (Coppermine)
stepping 06 (hey, I got it virtually for free), and my server/network
appliance will be based on an 1.3 GHz Tualatin Celery. Part of my choice
was a form factor, part of it was uncritical thermal and acoustical
