The basic idea is that all things don't remain equal. Some of the differences that can and do dominate frequency differences are the microarchitecture, resulting in machine instructions that aren't comparable even if both processors have a similar frequency, parallelism, resulting in a variable amount of instructions handled per clock cycle, and data transfer, resulting in clock cycles being wasted. GP argues that even though frequency has not increased recently, performance has, a point better made by the article.
