This desrves some attention. Existing 940 motherboards will be able to take
Dual Core CPUs. This means that single socket 940s can effectively run 2
CPUs. Dual socket motherboards, 4.

This is very different to Intel Hyperthreading - they appear as 2 CPUs in
Windows, but it's not really 2 complete CPUs. I think it's only two
"processing units".

It's not even that. Intel runs a second thread in the unused portions
of the chip on each clock cycle. This requires very little extra
logic. But it limits what can be done simultaneously to things that
don't use the same hardware.
