Hello there! I currently use a MacBook Air 11" from 2011 that's run by a 1.7 i7 GHz processor featuring a 3.3 GHz turbo boost. Now I've spoiled my eyes with the Retina screen of my iPad resulting in the upgrade of my "blurry" MBA to a MacBook Pro Retina 13". The turbo boost for both my current MBA as well as the MBPr of my choice (2.6 i5) is 3.3 GHz. I don't know how exactly this boost works, but I assume that under heavy usage the processor will jump into "boost mode" until the base clock speed cuts it again. I hence imagine that I will not see any speed improvements with the MBPr, "boost mode" will simply be used less often (and save battery life this way?). While my current MBA has to work with 4GB memory, the 8GB of the MBPr will be a welcome speed increase in multitasking (especially video rendering in the background). But will there be any noticeable power improvement processor-wise (eg faster rendering) if the maximum speed is the same 3.3 GHz? Of course, Haswell is a superior processor to whatever was used in 2011 (sandy bridge?), but how exactly does this play out in real life? Does it at all?
