I wouldn't suggest cpuboss or other boss sites as they rate on irrelevant spec comparisons and many benchmarks were shown to be wrong. Your link actually shows an instance on performance. Userbenchmark is ok but keep in mind they are based mainly on synthetics and not real world difference. It's good to get a quick general idea but that's it.
cpuboss does often have errors, but it also has a list of specs and some benchmark results so if you read the whole page and don't use it as your sole source of comparison it can still be useful. I did say neither site was perfect.
