The iMac "Core i5" 1.6 21.5-Inch Aluminium (Late 2015/Broadwell) features a 14-nm "Broadwell" 1.6 GHz Intel "Core i5" processor (5250U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 8 GB of onboard 1867 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of order, but cannot be upgraded after system purchase at all), a 1 TB (5400 RPM) hard drive, and an "integrated" Intel HD Graphics 6000 graphics processor that shares system memory. It also has a built-in "FaceTime HD" webcam and stereo speakers.

This model has a 21.5" 1920x1080 LED-backlit 16:9 widescreen IPS display with a fully laminated glass cover and an anti-reflective coating. The rear of the case is aluminium and is thicker in the middle and tapers to a razor thin 5 mm at the edges.

Connectivity includes four USB 3.0 ports, dual Thunderbolt 2 ports, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n compatible), and Bluetooth 4.0.
