Normally, it is tough to see the gap in sensor sizes purely by looking through technical specs. The pic below should give you a far better sense of the sensor sizes in the D800 and A77.

As you have seen, both of these cameras feature different megapixels and different sensor sizes.

Higher resolution will let you crop photographs way more aggressively. The more recent D800 is going to have an edge in sensor technology.
