The prediction made in 1965 by Gordon Moore, cofounder of Intel, that in the future the number of transistors on a chip would double every two years. Surprisingly, Moore’s prediction—based on the development of the then very new concept of the integrated circuit—still held true until the mid2010s. The Intel 4004 processor released in 1971 had 2300 transistors, whereas the most recent Intel 22-core Broadwell-EP Xeon processor has 7.2 billion. Over that period transistor sizes have shrunk from 10 micrometres to 14 nanometres.
