[Beowulf] XEON power variations

Intel assigns the same power consumption to different clockspeeds of L,
E, X series XEON. All L series have the same rating, all E series etc.
So, taking their numbers, the fastest of each type will always have the
best performance per watt. And there is no power consumption penalty
for buying the fastest clockspeed of each type. Vendor's power
calculators reflect this (dell.com/calc for example). To me this seems
like marketing simplification... Anybody know any different, e.g. have
you seen other numbers from vendors or tested systems yourself?
Is the power consumption of a system with an E5502 CPU really the same
as one with an E5540?
