The MacBook Pro "Core i5" 2.6 13-Inch (Early 2013 Retina Display) is powered by a 22 nm "Ivy Bridge" 2.6 GHz Intel "Core i5" processor (3230M). It features dual independent cores on a single chip, a 3 MB shared L3 cache, and 8 GB of onboard 1600 MHz DDR3L SDRAM that cannot be upgraded. The system includes 256 GB of flash storage, an integrated Intel HD Graphics 4000 processor sharing system memory, an integrated 720p FaceTime HD webcam, and a high-resolution 13.3-inch LED-backlit widescreen 2560x1600 (227 ppi) "retina" display. All this is housed in a chassis weighing just over 3.5 pounds (1.62 kg). It does not have an internal optical drive.
Connectivity options comprise 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. Adapters for Gigabit Ethernet or Firewire "800" were 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 a sealed internal battery providing an estimated 7 hours of use.
