GROSCH LAW RE-REVISITED - CPU POWER AND THE COST OF COMPUTATION

The author asks whether Grosch's law, which postulated that the costs of computer systems increase at a rate equivalent to the square root of their power, still holds. He concludes that the age of mini-, micro-, and supercomputers has 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.
