Nehalem gets all on die.The difference?

Until Nehalem NBs were typically 1 or 2 process generations behind. ( CPUs on 90nm NB were 130/180nm , CPUs 65nm NBs were 90nm/130nm ).

A NB typically burns 8-25w.Moving it inside the CPU and using the latest process tech will probably cut the power by 2-4x.
You can already get 65nm chipsets today to use with your 65nm CPU. So thats basicly just pragmatics. Also I dont hope a NB uses 25W...
If you note most of the powersavings is from a faster core. 30% less power consumption for the same performance as a Penryn. And if you have a scenario with 10-100% boost (Lowest single to highest multi). Then you have your 30% there.
