I did plan this, but upon getting the data, found it too difficult for the initial version. There's no standard for CPU (or most fields actually), so sellers write it in a variety of ways. But it could be done, after I compile a dataset of cpu > benchmarks.
I like passmark / cpubenchmark.net to get a good ballpark idea of CPU performance, because it covers a wide range of CPUs, and because it has both single-core and multi-core scores.
