The iMac “Core i3” 3.6 21.5-Inch Aluminum (Retina 4K, 2019/Coffee Lake) features a 14-nm “Coffee Lake” 3.6 GHz Intel “Core i3” processor (I3-8100) 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 “built into the computer” — but it actually can be upgraded later, it is just needlessly difficult — a 1 TB (5400 RPM) hard drive, and a Radeon Pro 555X graphics processor with 2 GB of dedicated GDDR5 video memory. 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. 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.
