Grosch's law re-revisited: CPU power and the cost of computation

Abstract

Does Grosch's law, which postulated that the costs of computer systems increase at a rate equivalent to the square root of their power, still hold? The age of mini-, micro-, and supercomputers seems to have complicated the situation. When computers are grouped according to their size and power, Grosch's law seems to hold within each group, but not between different groups. © 1985, ACM. All rights reserved.
