iMac Retina 5K, 27-Inch, 2020

The iMac "Core i7" 3.8 27-Inch Aluminum (Retina 5K, 2020/Comet Lake; Radeon Pro 5700/5700 XT) is a "configure-to-order" version of the iMac 27-Inch "Core i7" 3.8 (5K, 2020), also documented separately for user convenience. Besides the graphics processor, this model can be configured identically to its standard counterpart, though it has different identifiers (pending final confirmation).

This iMac features a 14-nm "Comet Lake" 3.8 GHz Intel "Core i7" processor (I7-10700K) with eight independent cores on a single chip, a 16 MB shared L3 cache, and a T2 Security Chip. It includes 8 GB of user-upgradable 2666 MHz DDR4 SDRAM, a default 512 GB onboard SSD, and either a Radeon Pro 5700 with 8 GB of dedicated GDDR6 memory or a Radeon Pro 5700 XT with 16 GB of dedicated GDDR6 memory. It also has a 1080p "FaceTime HD" webcam, a studio-quality three-mic array, and stereo speakers.

It sports a 27" 5120x2880 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 5K" display with True Tone technology. The aluminum rear case tapers to a slim 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 5.0.

Compared to its predecessor, this model is nearly identical in appearance but features a "True Tone" display (with a US$500 nano-texture option), an improved webcam, speakers, and microphone, and a more advanced processor, architecture, and graphics. By default, "2020" iMacs shipped with a compact aluminum Apple Magic Keyboard and "Magic Mouse 2". Upgrades were available for a "Magic Keyboard with Numeric Keypad" (US$30) and a "Magic Trackpad 2" (US$50).

As a configuration that pushed the graphics performance of the final Intel iMac generation to its limits, this model received high praise from highly specialized users. The Radeon Pro 5700 XT, with its massive 16GB of VRAM, delivered overwhelming performance in the most demanding tasks such as 4K/8K video editing, high-end 3D rendering, and VR development. [10, 23] The 8-core Core i7 processor and fast SSD storage provided a powerful foundation for this performance. [1, 10] It also benefited from all the improvements of the base model, including the T2 chip and 1080p camera, and was recognized for its value as the ultimate, no-compromise Intel Mac. [1, 10]
