Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, two USB 3.0 ports, two 'Thunderbolt 2' ports, an HDMI port, an audio in/out port, and an SDXC card slot. It does not have an internal optical drive. It also has an integrated 720p FaceTime HD webcam, and a high-resolution LED-backlit 13.3' widescreen 2560x1600 (227 ppi) 'Retina' display in a case that weighs just less than 3.5 pounds (1.58 kg). The MacBook Pro 'Core i7' 3.1 13-Inch (Early 2015 Retina Display) features a 14 nm 'Broadwell' 3.1 GHz Intel 'Core i7' processor (5557U), with dual independent processor 'cores' on a single silicon chip, a 4 MB shared level 3 cache, 8 GB of onboard 1866 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 128 GB, 256 GB, or 512 GB of 4 Lane PCIe-based flash storage, and an integrated Intel Iris Graphics 6100 graphics processor that shares memory with the system.

The processor (and the corresponding larger level 3 cache), are the only substantial differences between this model and its stock compatriots.

Starting on October 27, 2016, it only is a CTO option for the MacBook Pro 'Core i5' 2.7 13-Inch (Early 2015 Retina Display). The MacBook Pro 'Core i7' 3.1 13-Inch (Early 2015 Retina Display) originally was a 'configure-to-order' configuration for both the MacBook Pro 'Core i5' 2.7 13-Inch (Early 2015 Retina Display) and MacBook Pro 'Core i5' 2.9 13-Inch (Early 2015 Retina Display), but also is documented as a separate model for reader convenience.
