Intel Architecture (IA) ProcessorsIntel Architecture (IA) ProcessorsMoore's Law:In the mid-1960s, Intel Chairman of the Board Gordon Moore deduced a principle: the computing power and the complexity (or roughly, the number of transistors per CPU chip) of the silicon integrated circuit microprocessor doubles every one to two years, and the cost per CPU chip is cut in half.
