The MacBook Pro “Core i7” 3.1 15-Inch (Mid-2017 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) technically is a “configure-to-order” configuration of either the MacBook Pro “Core i7″ 2.8 15” Touch Bar/Mid-2017 or MacBook Pro “Core i7″ 2.9 15” Touch Bar/Mid-2017, but also is documented as a separate model for reader convenience. Other than processor, these models can be configured identically.
The MacBook Pro “Core i7” 3.1 15-Inch (Mid-2017 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) is powered by a 14 nm, 7th Generation “Kaby Lake” 3.1 GHz Intel “Core i7” processor (7920HQ), 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 and 256 GB or 512 GB of onboard flash storage (RAM cannot be upgraded at the time of purchase, but the flash storage can), and dual graphics processors — either an AMD Radeon Pro 555 with 2 GB of dedicated GDDR5 memory or an AMD Radeon Pro 560 with 4 GB of dedicated GDDR5 memory as well as 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 2880×1800 (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.
