The MacBook Pro 'Core i7' 2.9GHz 15-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) features a 2.9 GHz Intel 'Core i7' processor, with four independent processor 'cores' on a single silicon chip, an 8 MB shared level 3 cache, 16 GB of onboard 2133 MHz LPDDR3 SDRAM (which cannot be upgraded), 2 Terabyte (TB) of PCIe-based flash storage, and dual graphics processors -- an AMD Radeon Pro 455 with 2 GB of dedicated GDDR5 memory and an integrated Intel HD Graphics 530 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 15.4' widescreen 2880x1800 (220 ppi, 500 nits) 'Retina' display. This notebook is offered in either silver colored aluminum or a darker 'Space Gray' colored aluminum housing and weighs just a bit more than 4 pounds (1.83 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.
