Moore's law Moore's law Moore's law is the observation that the number of transistors in a dense integrated circuit doubles about every two years. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel, whose 1965 paper described a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years. The period is often quoted as 18 months because of a prediction by Intel executive David House (being
Doubling time in five years, and an Egyptian proverb of the time was "If wealth is placed where it bears interest, it comes back to you redoubled." Examining the doubling time can give a more intuitive sense of the long-term impact of growth than simply viewing the percentage growth rate For a constant growth rate of "r%", the formula for the doubling time "T" is given by Some doubling times calculated with this formula are shown in this table. Simple doubling time formula: For example, with an annual growth rate of 4.8% the doubling time is 14.78 years, and a doubling time
