"The MacBook Pro ""Core i7"" 2.6GHz, 15-Inch (2019, Touch Bar) is powered by a 14 nm, 9th Generation ""Coffee Lake"" 2.6 GHz Intel ""Core i7"" processor (I7-9750H), with six independent processor ""cores"" on a single silicon chip, a 12 MB shared level 3 cache, 16 GB of onboard 2400 MHz DDR4 SDRAM and 512 GB of onboard flash storage as well as dual graphics processors -- an AMD Radeon Pro 555X with 4 GB of dedicated GDDR5 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 revised ""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 2880x1800 (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 a faster processor as well as a tweaked butterfly keyboard said to use different materials and be less error prone."
