BareFeats’ rob-ART morgan asks and answers the rhetorical question: “is the 13″ Retina MacBook Pro just a smaller version of the 15″ Retina MacBook Pro?”
“Not exactly,” says rob, who notes that the new 13″ Retina MacBook Pro comes only with a Dual-Core i5 or Dual-Core i7 while the 15″ Retina MacBook Pro comes with a Quad-Core i7. Additionally, the 13-inch model is limited to an integrated Intel HD Graphics 4000 GPU with memory annexed from the operating system, while the 15-inch model comes with a discrete NVIDIA GeForce GT 650M with its own dedicated memory. Futhermore, the 13″ RMBP is limited to its hard-soldered standard 8 GB RAM configuration while the 15″ rMBP can be ordered with up to 16G.
Morgan conducted a shootout between the two rMBPs to illustrate the performance gap, which may be critical for users who run professional apps.
