The MacBook Pro "Core i5" 3.3 13-Inch (Mid-2017 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) is a "configure-to-order" version of the MacBook Pro "Core i5" 3.1 13-Inch (Mid-2017), also documented separately for clarity. Apart from the processor, these two models are identical.
This model is powered by a 14 nm, 7th Generation "Kaby Lake" 3.3 GHz Intel "Core i5" processor (7287U), with dual independent cores on a single chip, 64 MB of eDRAM on the processor die, and a 4 MB shared L3 cache. It comes with 8 GB of onboard 2133 MHz LPDDR3 SDRAM (upgradable to 16 GB only at purchase), 256 GB or 512 GB of flash storage, and an integrated Intel Iris Plus Graphics 650 processor that shares system memory.
Externally, it features an integrated 720p FaceTime HD webcam, a slim, backlit "second generation" butterfly mechanism keyboard with an integrated "Touch Bar" that adapts to applications and provides Touch ID login, and a large "Force Touch" trackpad. It also has a high-resolution 13.3-inch LED-backlit widescreen 2560x1600 (227 ppi, 500 nits) "Retina" display and an integrated battery with an estimated 10-hour runtime.
Available in silver or a darker "Space Gray" aluminum, this notebook weighs just over 3 pounds (1.37 kg). Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.2, four "Thunderbolt 3" ports (USB-C), and a 3.5 mm headphone jack.
Compared to its predecessor, this model is externally almost identical but has a more advanced processor and architecture.
