In addition to the standard configurations of its Macs, Apple offers a number of build-to-order (BTO) upgrade options that include more RAM, more storage capacity, and faster processors. An "ultimate" configuration is a customized machine with the fastest options available. We’ve tested the ultimate configuration of the 13-inch Retina MacBook Pro and found that the performance—as well as the price tag—were both considerably higher than the standard high-end configuration.
The $2799 15-inch Retina MacBook Pro costs just $100 more than our ultimate 13-inch laptop and was 34 percent faster overall. The 15-inch Retina laptop was also 65 percent faster in our MathematicaMark tests.
