Just as an aside, the power savings going from two single-core CPUs
to one dual-core can be rather impressive. At work I run a computing
cluster on AMD64 hardware, and we've been studying replacing our 2-
socket single-core compute nodes with half as many 2-socket dual-core
systems, and doing some similar consolidation of our support
servers. Part of the motivation for this is we've exceeded our
available A/C capacity. I ran the numbers and at the same clock
speed (2.8 GHz) we could cut our power consumption (and, by
extension, our heat generation) by a third. By giving up 200 MHz per
chip to switch to HE-series CPUs we could cut it by almost half.
