Intel gets lower power by turning off individual pipelines if they are not addressed by the current instruction cycles. It takes a clock or two to turn them back on if they get addressed, so that adds a bit of delay to that execution.

AMD turns off whole sections, like all MMX or all floating point, but does much less turning off subsections. This makes them faster, but they are driving all the pipelines whether the instruction needs them or not.

I expect AMD will have to adapt more low power techniques as they move to quad-core devices.
