iMac 21.5 -inch (Retina 4K) 3.0GHZ Quad Core i5 (Mid 2017).

The iMac “Core i5” 3.0 21.5-Inch Aluminum (Retina 4K, Mid-2017/Kaby Lake) features a 14-nm “Kaby Lake” 3.0 GHz Intel “Core i5” processor (7400) with four independent processor “cores” on a single chip, a 6 MB shared level 3 cache, 8 GB of 2400 MHz DDR4 SDRAM that is reportedly onboard — but actually can be upgraded later — a 1 TB (5400 RPM) hard drive, and a Radeon Pro 555 graphics processor with 2 GB of dedicated VRAM.

It also has a built-in “FaceTime HD” webcam and stereo speakers.

This model has a 21.5″ 4096×2304 LED-backlit 16:9 widescreen IPS DCI-P3 “Retina 4K” display (that runs “pixel doubled” to look like 2048×1152).

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.

Compared to its predecessor, this model essentially has the same external enclosure, but it has a more advanced processor and architecture as well as dedicated graphics, a brighter display, and Thunderbolt 3 (USB-C) ports.
