The growth in processor power over the last 40 years seems so uniform that it almost has the status of a law of nature. Moore’s Law, as it is called, states that the number of transistors on a chip doubles every two years. We don’t know how long it will hold true, but here are some of the most significant chips and devices this growth has made possible.
