2. “Till about 2002 you could safely misinterpret Moore’s law as promising that clock speeds would double every 18 months. Actually what it says is that circuit densities will double every 18 months.” 2 “It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU” “Not any more. Intel can no longer give us faster CPUs, just more of them.” (Paul Graham) GPU as a Service (GaaS) - AWS Hackathon Berlin 2012
