You do the math. If Apple included the Retina display and added some fresh powerful GPU on it, would it be more powerful than the previous generation? I mean, of course it would be but let's say you're playing a game and the previous generation is also playing a game. Which one would have the higher frame rate? I'm worried about this because if the Retina Display will reduce the MacBook Pro's performance, then the Retina Display isn't ready to meet the computers.
