Do you have a source for that? The thesis of this article is that it is a more powerful CPU, in terms of performance-per-watt, which is the same metric that spawned the PowerPC-to-Intel transition. The author pointed to specific ARM chips that exist today which "consume less power, about 210 watts, than a competing Xeon CPU needing as much as 400 wats, for about the same amount of computing".
