The MacBook Pro "Core i5" 2.7 13-Inch (Early 2015 Retina Display) is powered by a 14 nm "Broadwell" 2.7 GHz Intel "Core i5" processor (5257U), with dual independent cores on a single chip and a 3 MB shared L3 cache. It includes 8 GB of onboard 1866 MHz LPDDR3 SDRAM (upgradable to 16 GB at purchase, but not later), and by default, 128 GB or 256 GB of 4-Lane PCIe-based flash storage (only 128 GB by default from Oct 27, 2016). It also features an integrated Intel Iris Graphics 6100 processor sharing system memory, a 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 (1.58 kg). It lacks an internal optical drive.
Connectivity comprises 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, an innovative haptic-capable "Force Touch" trackpad, and a sealed internal battery providing an estimated 10 to 12 hours of use.
Compared to its predecessor, this model appears nearly identical externally but features a more advanced processor and architecture, a more capable graphics processor, faster RAM, a quicker SSD, and a higher-capacity battery, along with the advanced "Force Touch" trackpad.
