Is CPU frequency really an accurate metric for determining relative performance of different hardware ? It seems maximum CPU frequency of CPUs has rather plateaued, and chip vendors have been following different avenues to improve performance of their chips such as multicore, multhreads, and various other architectural changes. So I'm not sure that just having a filter that compares CPU frequency is neccessarily going to give useful results. ie faster frequency no longer neccessarily implies faster performance.
