(GIGAOM): Both mobile and high-performance computing are placing huge power efficiency and performance demands on chips, but the $64,000-question is how long until such extreme computing use cases hit the server mainstream. Asked another way, the question becomes, how long until Amazon Web Services adopts ARM-based servers. Or perhaps it isn’t ARM-based servers, but a variation on an Intel chip that takes its architecture from some of the more innovative and energy-efficient silicon out today. For example, Adapteva, a startup I profiled back in May, released a 64-core chip on Monday that can deliver 70 gigaflops of performance per watt. If you don’t speak gigaflops, that’s okay: It basically has done what Intel and certain countries have deemed impossible with the current generation of silicon. Full Article
