Matt has this weariness he often employs in his performance. Most recent example I can remember is in Closing Time, when he's telling Craig he dies tomorrow, as Craig and Stormy nod off. It's something Tennant, at least, lacks. But I think that has less to do with him trying to portray the Doctor's age and more to do with that plot involving the Doctor coming to terms with his impending doom.
Matt doesn't play an old Doctor, he plays a Doctor for whom the nature of his age is far more ambiguous. I'd argue they all did this in their own way- the youthfulness of some of the "older" Doctors, Tennant's ridiculous energy and faith, Eccleston's excitement and anger that flipped between that of a young man and that of one whose seen the world burn and is pissed off with it all. But Smith's style of weariness and a sense that he's only just holding on to the youthful manner his past incarnations called upon so much definitely invokes the vibe of an older man more than most regenerations.
