The MacBook Pro "Core i7" 3.3 13-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) technically is a "configure-to-order" configuration of the MacBook Pro "Core i5" 2.9 13-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports), but also is documented as a separate model for reader convenience. Other than processor, these two models are identical.
The MacBook Pro "Core i7" 3.3 13-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) features a 14 nm, 6th Generation "Skylake" 3.3 GHz Intel "Core i7" processor (6567U), with dual independent processor "cores" on a single silicon chip, a 4 MB shared level 3 cache, 8 GB of onboard 2133 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 256 GB or 512 GB of PCIe-based flash storage, and an integrated Intel Iris Graphics 550 graphics processor that shares memory with the system.
This notebook also has an integrated 720p FaceTime HD webcam, a thin, backlit "second generation" butterfly mechanism keyboard with an integrated new "Touch Bar" that replaces the traditional function keys with a touch-sensitive control that adapts for different applications and provides Touch ID login support, and a gigantic "Force Touch" trackpad.
Additionally, it has a high-resolution LED-backlit 13.3" widescreen 2560x1600 (227 ppi, 500 nits) "Retina" display, and a integrated battery that provides an Apple estimated 10 hours of runtime.
