Finally! Somebody has performed a power consumption comparison between Intel Core i7 processors for laptops and Core 2 ones in similar configurations. The conclusion: a Core i7-920XM draws a 32% more power than a Core 2 Extreme QX9300 when idle, a 24% when playing a DVD. The performance benefit is ar0und 20% (between 0 and 36%, in general), so the efficiency of this new processors is not impressive. It would be very interesting to see data from the non-Extreme processors, but the results would be probably similar.
