I'm currently working with a chip that has several hardware "threads". On a
single piece of code it's performance is not great, but when you have 2 or
more threads it's performance per watt can be quite impressive.
Also bear in mind that Intel chips are constrained very much by their legacy.
If you have a specific load (e.g. floating point, integer, I/O, DSP, highly
concurrent) it is not that difficult to build a chip that is faster than a
more general purpose processor.
At present it doesn't run Erlang however. :-)
