The theory is that they had bigger brains - e.g. see the reference at:

Yes, but they also had more massive bodies, possibly 30% more massive than modern humans. I'm not sure that they had a higher brain/body mass ratio than we do and even if they had, a difference on the order of 10% isn't strong evidence when comparing intelligence between species.
