I would argue that Cinebench is not particularly indicative of the real-world performance of CPUs; I know that AMD has a tendency to use it because it produces better numbers for their CPUs, but Cinema4D's integrated renderer that Cinebench is based on is somewhat outdated now. From the various benchmark results floating around the release of the Ryzen 3 CPUs, both Corona and V-Ray seem to produce very similar results compared to Intel CPUs.
