The MacBook Pro "Core i7" 2.8 15-Inch (Mid-2017 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) is powered by a 14 nm, 7th Generation "Kaby Lake" 2.8 GHz Intel "Core i7" processor (7700HQ), 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 and 256 GB of onboard flash storage, and dual graphics processors -- an AMD Radeon Pro 555 with 2 GB of dedicated GDDR5 memory and an integrated Intel HD Graphics 630 graphics processor that shares memory with the system.
Externally, this notebook has an integrated 720p FaceTime HD webcam, a thin, backlit "second generation" butterfly mechanism keyboard with an integrated "Touch Bar" touch-sensitive control that adapts for different applications and provides Touch ID login support in lieu of traditional function keys, 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 a 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.
Compared to its predecessor, this model is effectively identical externally, but has a more advanced processor and architecture.
