The Apple MacBook Air "Core i5" 1.6 13-Inch (Retina, Late 2018) model features a 14-nm "Amber Lake Y" 1.6 GHz Intel "Core i5" processor (8210Y) with two independent processor "cores" on a single chip, a 4 MB shared level 3 cache, 8 GB of onboard 2133 MHz LPDDR3 SDRAM and 1.5TB onboard PCIe-based flash storage, and an "integrated" Intel UHD Graphics 617 graphics processor that shares system memory. Both the RAM and the SSD can be upgraded at the time of initial system purchase, but not subsequently.
This all is packed in a thin wedge-shaped aluminum case with an integrated 720p "FaceTime HD" webcam, Touch ID, a thin, backlit "third generation" butterfly mechanism keyboard, large "Force Touch" trackpad, and a high-resolution 13.3" LED-backlit 2560x1600 (227 ppi) "Retina" display.
