The Apple MacBook Air "Core i5" 1.4 11-Inch (Early 2014/Haswell) features a 22-nm "Haswell" 1.4 GHz Intel "Core i5" processor (4260U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard1600 MHz LPDDR3 SDRAM (which could be upgraded to 8 GB at the time of purchase, but cannot be upgraded later), 128 GB or 256 GB of PCIe-based flash storage, and an "integrated" Intel HD Graphics 5000 graphics processor that shares system memory.

This all is packed in a razor thin (0.11-0.68 inch), 2.3 pound, aluminum case with an integrated 720p "FaceTime HD" webcam, a backlit full-size keyboard and an 11.6" widescreen TFT LED backlit active-matrix "glossy" display (1366x768 native resolution).

Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, analog audio out, a "Thunderbolt" port, and two USB 3.0 ports.

Compared to its predecessor, this model is practically identical -- with the same design and architecture -- but it has a faster processor, longer reported battery life (due to OS X improvements rather than hardware), and a few, but not many, different identifiers, as well.
