In the CPU wars one of the things that gets thrown back and forth is how much power the CPU uses. IN some cases we see high numbers that are excused by high performance while other times a lower performing CPU might be labeled "efficient".
With all of this going back and forth it is interesting to note that Intel's Sandy Bridge could see a rather impressive 25% reduction in power over Intel's current Core i7 usage. This number is very surprising given some of the TDPs we have seen in the not too distant past. A 25% reduction is even more impressive when you consider that Nehalem, Lynnfield and Clarkdale are already fairly efficient in their own rights.
