Supposedly the A55 and A65/77 use the same sensor technology while the A57 sensor was "tweaked" for better high iso. The problem with that is DXO scores the A55 sensor a touch better at high iso than the A57 (although the difference is insignificant). There must be a margin of error in the DXO tests. Somebody else said 1/3 - 1/2 stop MOA.

Miss use of the ability to do 100% pixel peeping is the bane of digital photography because it causes people to fret over inconsequential issues.
