The MacBook Pro “Core i9” 2.9 15-Inch (Mid-2018 True Tone Display, Touch Bar, Four Thunderbolt 3 Ports, Vega 16/Vega 20) is a “configure-to-order” configuration of the MacBook Pro “Core i7″ 2.6 15” Touch/Mid-2018, but with a faster processor and a Vega 16 or Vega 20 video card. Unusually, this custom video card results in different system identifiers (as well as operating system support), and the notebook also is documented as a separate model for reader convenience, accordingly.
The MacBook Pro “Core i9” 2.9 15-Inch (Mid-2018 True Tone Display, Touch Bar, Four Thunderbolt 3 Ports, Vega 16/Vega 20) is powered by a 14 nm, 8th Generation “Coffee Lake” 2.9 GHz Intel “Core i9” processor (8950HK), with six independent processor “cores” on a single silicon chip, a 12 MB shared level 3 cache, 16 GB of onboard 2400 MHz LPDDR4 SDRAM — which could be upgraded to 32 GB at the time of purchase, but cannot be upgraded later — and 512 GB of onboard flash storage standard, and dual graphics processors — an AMD Radeon Pro Vega 16 or Radeon Pro Vega 20 with 4 GB of dedicated HBM2 memory and an integrated Intel UHD Graphics 630 graphics processor that shares memory with the system.
Externally, this notebook has an integrated 720p FaceTime HD webcam, a thin, backlit “third 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 with True Tone technology, 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 5.0, four “Thunderbolt 3” ports (USB-C connector), and a 3.5 mm headphone jack.
Compared to its predecessor, this model has an improved display and keyboard as well as a more advanced processor and architecture and the option of twice as much RAM and storage by custom configuration.
