Moore’s Law (Transistors per Microprocessor), 1971-2020

In 1965 Gordon Moore, co-founder of the microprocessor manufacturer Intel, predicted that the number of transistors per integrated circuit would double every 18 months. So far, his assumption remains reasonably true as microprocessors saw their number of transistor equivalent jump from 2,250 in Intel’s 4004 (1971) to 731 million in Intel’s Pentium iCore 7 (2008) and 2.6 billion for the Xeon (2011). Thus, a doubling every 24 months permitted the development of the information economy where massive processing power is required. There are, however, physical limits to this process since electric current cannot effectively flow once a size threshold is reached in miniaturization.
