In 1973, Gordon Moore, one of Intel’s founders, predicted that the number of transistors that could be placed on a single silicon chip would double every 18 months, equivalent to an annual growth rate of 59% (i.e., 1.591.5 = 2.0). The first microprocessor was built in 1971 and had 2,250 transistors. In 2019, the AMD Epyc chip contained 32 billion transistors, 1.42 million times the number of transistors 48 years earlier. What has been the annual compound rate of growth in processing power? How does it compare with the prediction of Moore’s law?
