Question

State Pollack’s rule and prove that if you double the number of transistors in a processor, the chances are that you will only get a speedup of about 40 per cent.

Answer 1

Pollack’s rule states that the performance of a processor, P is directly proportional to the square root of its increase in complexity which is dependent on the number of transistors, T.

which is an approx. 40% increase in the original performance P1.
