For the same reason they don't design memory-CPU blocks bonded with heat
dissipation + networking, all in a handy pluggable module. Customers
apparently don't want it. AMD is losing credibility with the user base
right now, though, because it doesn't offer thermal protection. A naked
AMD CPU would self-destruct in less than a second.

Copper and diamond heat spreaders should be there quite soon, and advent
of liquid cooling is unavoidable. Voltage and structure shrink still gives
us some headway, but current designs are rapidly getting uncomfortably
hot. Asynchronous designs and power saving should do better, and even
reversible logic in semiconductors, eventually.

Latter is a must for computronium, of course.
