Again, I am mostly interested because it would be representative of architectural efficiency to perform such a test. If the top-spec processor is more efficient at a given power level than another, the same applies to lesser processors as well, in general (in particular, laptops and the like) This comparison is meaningless though if the processors aren't running at the same power, however :(
