Some new benchmarks from Geekbench show that the new MacBook Pros with Retina displays only show a 3-5% increase from its predecessors. The new MacBook Pros received an upgrade to their processors, and some received increased storage space. Because of the launch of its new MacBooks, Apple has lowered the prices on its previous models. The previous models may appeal to those of you who want a MacBook Pro with Retina display, but don't necessarily need the extra 5% boost. You'll save hundreds of dollars as well.
