The Apple MacBook Air "Core i5" 1.4 13-Inch (2014) featured
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 onboard 1600 MHz LPDDR3 SDRAM (which could be upgraded to 8 GB at the time of purchase, but cannot be upgraded later),
128 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,
2.96 pound, aluminum case with
an integrated 720p "FaceTime HD" webcam,
a backlit full-size keyboard and
a 13.3" widescreen TFT LED backlit active-matrix "glossy" display
(1440x900 native resolution).

Connectivity includes
802.11ac Wi-Fi,
Bluetooth 4.0,
analog audio out,
a "Thunderbolt" port,
two USB 3.0 ports, and
an SDXC-capable SD card slot.

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.
