Does non retina vs retina make a difference in game performance speed?

I'm getting a MacBook Pro. Don't convince me to get a different computer, I grew up with macs my whole life. Anyways, I want to get minecraft, which I'm pretty into. I play on very crowded servers, and take lots of screenshots. I like high settings, and I expect to 30-40 fps at all times. This is why I'm planning the non retina: because I don't care that much about screen quality. I'm getting the i5 13 inch. I know retina is literally ALWAYS at least 40 fps, but does non retina preform the same? I think it might preform better because the specs were higher. And it's $200 cheaper! So should I still get the non retina, or is non retina gonna kill my fps. Thanks!
