and also instead of just idles of "nop" statements, I believe that it uses instructions that minimise gate operations which reduces power consumption and hence heat production. On my Athlon 1.4 room heater it means a drop of 2-4 degrees c over a light load. A kernel complile or long mp3 encode can mean a rise of 10 degree's c above the idle level for comparison. Not a lot of advantage for a desktop, but well worth while for a laptop.
