The iMac "Core i5" 3.0 21.5-Inch Retina 4K features a 3.0 GHz Intel "Core i5" processor (I5-8500) with six independent processor "cores" on a single chip, a 9 MB shared level 3 cache, 8 GB of 2666 MHz DDR4 SDRAM that is reportedly "built into the computer" -- but it actually can be upgraded later, it is just needlessly difficult -- a 256 GB SSD standard and a Radeon Pro 560X graphics processor with 4 GB of dedicated GDDR5 video memory. It also has a built-in "FaceTime HD" webcam and stereo speakers.

This model has a 21.5" 4096x2304 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 4K" display (that runs "pixel doubled" to look like 2048x1152). The rear of the case is aluminum 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 3 (USB-C) ports, Gigabit Ethernet, 802.11ac Wi-Fi, and Bluetooth 4.2. It does not have a T2 chip.

Compared to its predecessor, this model is very similar externally and internally, but it has a more advanced processor and architecture as well as graphics processor.
