The MacBook Pro "Core i5" 2.4 13-Inch (Late 2013 Retina Display) is driven by a 22 nm "Haswell" 2.4 GHz Intel "Core i5" processor (4258U), with dual independent cores on a single chip and a 3 MB shared L3 cache. It comes with either 4 GB or 8 GB of onboard 1600 MHz DDR3L SDRAM (not upgradable after purchase, though a 16 GB option was available at the time of order), 128 GB or 256 GB of PCIe-based flash storage, and an integrated Intel Iris 5100 graphics processor that shares system memory. It also features an integrated 720p FaceTime HD webcam and a high-resolution 13.3-inch LED-backlit widescreen 2560x1600 (227 ppi) "Retina" display, all in a chassis weighing just under 3.5 pounds (1.57 kg). There is no internal optical drive.
Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt 2" ports, an HDMI port, an audio in/out port, and an SDXC card slot.
Additionally, 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 9 hours of life.
Compared to its predecessor, this model not only features a slimmer housing but also boasts a faster, more efficient "Fourth Generation" processor and architecture, leading to longer battery life. It also offers improved graphics, storage, and Wi-Fi speeds, along with enhanced connectivity.
