I think Ryan8bit misspoke, but we'd have to factor in that the ST09 was essentially an origin story, and very specifically set a few years chronologically before TOS (2258 vs. 2265), so the characters -- and thus the actors -- are going to be slightly younger. Or, if you want to consider the Cage in 2254, then the two Spocks more or less line up (except Spock is a Commander in the reboot and Lt. in the Cage).
