The MacBook Pro “Core i5” 2.9 13-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports)
features a 14 nm, 6th Generation “Skylake” 2.9 GHz Intel “Core i5” processor (6267U),
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,
256 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 2560×1600 (227 ppi, 500 nits) “Retina” display,
and a integrated battery.

This notebook was offered in either silver colored aluminum or a darker “Space Gray” colored aluminum housing (but not other colors) and weighs just a bit more than 3 pounds (1.37 kg).

Connectivity includes:
802.11ac Wi-Fi,
Bluetooth 4.2,
four “Thunderbolt 3” ports (USB-C connector),
and a 3.5 mm headphone jack.

Compared to its predecessor, this model has a completely different external housing that is thinner, is available in another color option, and has the aforementioned “Touch Bar” in addition to a larger trackpad, but swaps a variety of ports for just four Thunderbolt 3 ports and a 3.5 mm headphone jack.

Internally, it has a more advanced processor and architecture, as well as a more advanced graphics processor and better speakers, but reduced battery life.
