'''Pollack's rule''' states that the performance increase delivered by [[microarchitectural]] improvements is roughly proportional to the square root of the increase in logic complexity. In other words, in order to double the performance of a design, you need to quadruple the logic complexity or alternatively doubling the logic in the [[physical core|core]] will deliver roughly 1.4x more performance. | '''Pollack's rule''' states that the performance increase delivered by [[microarchitectural]] improvements is roughly proportional to the square root of the increase in logic complexity.
