Moore's law 2015 that the pace of advancement has slowed, starting at the 22 nm feature width around 2012, and continuing at 14 nm. Brian Krzanich, the former CEO of Intel, announced, "Our cadence today is closer to two and a half years than two." Intel is expected to reach the 10 nm node in 2018, a three-year cadence. Intel also stated in 2017 that hyperscaling would be able to continue the trend of Moore's law and offset the increased cadence by aggressively scaling beyond the typical doubling of transistors. Krzanich cited Moore's 1975 revision as a precedent for the current deceleration,
Rule of 72 by 200/(200−"r") as follows: For example, if the interest rate is 18%, the rule of 69.3 says "t" = 3.85 years. The E-M rule multiplies this by 200/(200−18), giving a doubling time of 4.23 years, where the actual doubling time at this rate is 4.19 years. (The E-M rule thus gives a closer approximation than the rule of 72.) Note that the numerator here is simply 69.3 times 200. As long as the product stays constant, the factors can be modified arbitrarily. The E-M rule could thus be written also as in order to keep the product mostly unchanged. In
