ARM chief tosses Moore's Law out with the trash, says efficiency rules all

ARM CEO Warren East already has a tendency to be more than a bit outspoken on the future of computing, and he just escalated the war of words with an assault on the industry's sacred cow: Moore's Law. After some prompting by MIT Technology Review during a chat, East argued that power efficiency is "actually what matters," whether it's a phone or a server farm. Making ever more complex and power-hungry processors to obey Moore's Law just limits how many chips you can fit in a given space, he said. Not that the executive is about to accept Intel's position that ARM isn't meant for performance, as he saw the architecture scaling to high speeds whenever there was a large enough power supply to back it up. East's talk is a bit long on theory and short on practice as of today -- a Samsung Chromebook isn't going to make Gordon Moore have second thoughts -- but it's food for thought in an era where ARM is growing fast, and even Microsoft isn't convinced that speed rules everything.
