From a different angle: Merom will have a ~30% better performance per watt than Yonah. Ofcourse Merom has higher TDP, but it has higher integer performance because of 64b as well. Merom has twice the performance per watt compared to current Pentium M (Dothan), due to DC and 64b which increase performance per watt, and higher TDP which probably decreases performance per watt. Yonah has 50% higher performance per watt than Dothan, due to dual core almost exclusively (not 64b). The other comparisons are comparing architectures that are rather different which makes interpreting the difference in performance per watt much more complex. Also it's impossible to tell if Conroe has a lower or higher integer performance per watt than Merom. We don't know how integer performance per watt was measured.
