The MacBook Pro "Core i7" 2.6 15-Inch (Late 2016 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) features a 14 nm, 6th Generation "Skylake" 2.6 GHz Intel "Core i7" processor (6700HQ), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 16 GB of onboard 2133 MHz LPDDR3 SDRAM (which cannot be upgraded), 256 GB of PCIe-based flash storage, and dual graphics processors -- an AMD Radeon Pro 450 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, and an integrated battery that provides an Apple estimated 10 hours of runtime. This notebook is 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 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.
