Bar, Four Thunderbolt 3 Ports) features a 14 nm, 6th Generation 
"Skylake" 2.6 GHz Intel "Core i7" processor (6700HQ), with <i>four</i> independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 16 GB of <i>onboard</i> 2133 MHz LPDDR3 SDRAM (which <i>cannot</i>

memory with the system.<br><br>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.<br><br>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.<br><br>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).<br><br>Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.2, <i>four</i> "Thunderbolt 3" ports (USB-C connector), and a 3.5 mm headphone jack.<br><br>Compared to its <a >predecessor</a>,
 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. Internally, 
it has a more advanced processor and architecture, as well as a more 
advanced graphics processor and better speakers, but reduced battery 
life.
