The MacBookPro10,2 entry could refer to a new Retina display version of the MacBook Pro since it’s identifier is similar to that of the 15in MacBook Pro with Retina display.
The 15in Retina MacBook is referred to as MacBookPro10,1 in Geekbench results while the non-Retina versions are known as MacBookPro9,x.
There is no evidence that Apple would use Geekbench to test its new machines. Geekbench is used by people creating Hackintoshes, so the fact that some machines with different specs and different names should come as no surprise.
However, Geekbench developer Primate Labs told AppleInsider that they believe the entry is genuine because the OS version number, processor model, motherboard and BIOS strings, all appear to be legitimate.
