The measure of brain computational power is not the volume or size of a brain. Cortical surface area is the important factor. The human brain is folded with gyri and sulci making up the ridges and the valleys of the folds. This folding allows for much greater surface area to be packed into our smaller by volume brains.
So just because a hominid skull is found that is larger does not necessarily mean that hominid was more intelligent. How complex was the brain in that big skull.
