The Retina display-powered MacBook Pro is out in 15-inch, but what of the smaller 13-inch model? Well, it appears that unverified benchmarks of an unreleased MacBook Pro model running an unreleased build of Mountain Lion ended up in the logs of benchmarking tool, Geekbench.
The new non-Retina 13-inch MBP has the model identifier "MacBookPro9,2", while the 5-inch non-Retina model is "MacBookPro9,1" and the corresponding Retina model is "MacBookPro10,1". Of course, the machine name for the MacBookPro10,2 could have been faked, but the information listed on the Geekbench result is pretty consistent with what would be expected from a new 13-inch MBP.
The unreleased machine is, according to the Geekbench results, running a 2.9GHz Intel Core i7-3520M, and runs Built 12A2056 of OS X Mountain Lion. We should hear more of a 13-inch Retina MacBook Pro in the coming months once we get closer to its launch.
