iMac Retina 5K, 27-Inch, 2019

The iMac "Core i5" 3.7 27-Inch Aluminum (Retina 5K, 2019/Coffee Lake) is equipped with a "9th Generation" 14-nm "Coffee Lake" 3.7 GHz Intel "Core i5" processor (I5-9600K). It features six independent cores on a single chip, a shared 9 MB level 3 cache, 8 GB of user-upgradable 2666 MHz DDR4 SDRAM, a 2 TB Fusion Drive, and a Radeon Pro 580X graphics processor with 8 GB of dedicated GDDR5 video memory. An integrated "FaceTime HD" webcam and stereo speakers are also included.

This model boasts a 27-inch 5120x2880 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 5K" display. The aluminum rear enclosure is thicker in the middle, tapering to a razor-thin 5 mm at the edges. Connectivity options include 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 security chip.

In comparison to its predecessor, this model is physically and internally very similar, but it benefits from a more advanced processor, architecture, and graphics processor. By default, the "2019" iMacs were shipped with a compact aluminum Apple Magic Keyboard and the multi-touch "Magic Mouse 2". For an extra US$30, the keyboard could be upgraded to the "Magic Keyboard with Numeric Keypad," and for an additional US$50, the Magic Mouse 2 could be exchanged for a "Magic Trackpad 2," which offers multi-touch and pressure-sensitive "Force Touch" capabilities.

As the top-of-the-line 27-inch 5K iMac, this machine boasted overwhelming performance with its 9th generation 6-core Core i5 processor and powerful Radeon Pro 580X graphics with 8GB of VRAM. It handled extremely demanding tasks like video editing, 3D rendering, and VR content creation with ease, earning it rave reviews from professional users. The 2TB Fusion Drive offered a good balance of capacity and speed, though users seeking peak performance opted for an SSD upgrade. The ease of RAM upgrades further enhanced this model's value.
