The Apple MacBook Air "Core i5" 1.6 11-Inch (Early 2015/Broadwell) is powered by a 14-nm "Broadwell ULT" 1.6 GHz Intel "Core i5" processor (5250U), which integrates two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard 1600 MHz LPDDR3 SDRAM (upgradable to 8 GB at the time of purchase, but not subsequently), either 128 GB or 256 GB of PCIe-based flash storage, and an "integrated" Intel HD Graphics 6000 graphics processor that shares system memory.
All of this is enclosed in a slim (0.11-0.68 inch), 2.3-pound aluminum case featuring an integrated 720p "FaceTime HD" webcam, a backlit full-size keyboard, and an 11.6-inch widescreen TFT LED-backlit active-matrix "glossy" display with a native resolution of 1366x768.
Connectivity options include 802.11ac Wi-Fi, Bluetooth 4.0, analog audio out, a single "Thunderbolt" 2 port, and two USB 3.0 ports.
Compared to its predecessor, this model appears virtually identical but incorporates a more advanced processor and architecture, superior graphics, longer stated battery life, and support for Thunderbolt 2. It also has some different identifiers.
