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. :-)
