TBH, there are people way more qualified in this area than I, but AFAIK Intel CPUs run at the turbo speed as long as they have sufficient cooling, and the benchmarks run at maximum performance available, which would be 4.7GHz in this case. Therefore, the benchmarks should be pretty close to your OC. You could verify this theory by running the benchmark yourself.
