The MacBook Pro "Core i7" 2.7 15-Inch (Early 2013 Retina Display) features a 22 nm "Ivy Bridge" 2.7 GHz Intel "Core i7" processor (3740QM), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 16 GB of onboard 1600 MHz DDR3L SDRAM (which cannot be upgraded), 512 GB of flash storage, dual graphics processors -- a NVIDIA GeForce GT 650M with 1 GB of dedicated GDDR5 memory and an "integrated" Intel HD Graphics 4000 graphics processor that shares system memory, an integrated 720p FaceTime HD webcam, and a high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "retina" display with a thin, sleek case design that weighs a bit less than 4.5 pounds (2.02 kg). It does not have an internal optical drive. Connectivity includes 3-stream AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt" ports, an HDMI port, an audio in/out port, and an SDXC card slot. It does not have Gigabit Ethernet or Firewire "800," although adapters are available at extra cost. In addition, this model has a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, a "MagSafe 2" power adapter, and an internal, and glued battery that provides an Apple estimated 7 hours of battery life.
