I don't see 10% baseline improvement over a single generation as significant as the power consumption decrease over the same generation. Probably just me.
What is striking is the 300% improvement that the mobile processor brought for Intel. Those who were around then will remember that Conroe was the desktop version of a laptop chip that was designed by a small Israeli acquisition of Intel's, because all they could muster up were lots of megahertz - at one point reachimg ridiculous levels - and massively long pipelines. Which basically led to the infamy that was Presshot. Intel was making lots of fumbles *ahem* Rambus *ahem* but since they had been in the game for very long they had the funds to dig themselves out of a hole.
Given that long term desktop future is uncertain, maybe looking hard at mobile is what Intel needs to do again. After all, that's where Conroe came from.
