Intel's low power plays

There is an interesting "Power Plays" discussion of Intel's focus on low power at Ars Technica.

There is a lot of work going on to optimize current enterprise server designs to use less power, this is good, but its not the order of magnitude difference that a move to Millicomputing based designs would provide.

The most interesting new technology described is an interconnect that uses very low power and which scales its clock rate and power consumption according to the bandwidth demand. This brings variable capacity to the network layer, and I'd love to see some very low power Intel CPUs with this technology integrated.
