Grosch's law
Grosch's law is the following observation of computer performance, made by Herb Grosch in 1953:
I believe that there is a fundamental rule, which I modestly call "Grosch's law", giving added economy only as the square root of the increase in speed — that is, to do a calculation ten times as cheaply you must do it hundred times as fast.
This adage is more commonly stated as
Computer performance increases as the square of the cost. If computer A costs twice
money drives good money out of circulation if their exchange rate is set by law." Coined in 1858 by British economist Henry Dunning Macleod, and named for Sir Thomas Gresham (1519–1579). The principle had been stated before Gresham by others, including Nicolaus Copernicus.
