It is said that Intel's newest revision of the Pentium 4 with the 'J' suffix that incorporates Execute Disable-bit supports also uses less power. According to someone from Intel at the latest Intel Developer Forum this new revision uses 20% less power than the Pentium 4 D0-stepping!
Someone at the XtremeSystems Forums got one of these CPUs in his hands and was able to overclock this CPU to 6.3GHz with a tripple phase-change that keeps the CPU temperature at a chilly -121°C. More about this overclock here
