Rob for Bare Feats:
If apps like Aperture and Motion are your “bread and butter,” you can conclude from this test session that the 2012 MacBook Pro (Retina and ‘normal’) performs on par with the best Mac Pro with the best graphics cards.
Aperture has always been a dog in terms of performance and thus I have usually preferred Lightroom. However since getting the retina MacBook Pro I have switched back to Aperture and haven’t noticed that dog slow performance in Aperture. Maybe the hardware has finally caught up, maybe Apple got around to optimizing Aperture.
I do get some good satisfaction from how favorably the retina MacBook Pro and MacBook Pro compare to Mac Pros.
