The iMac "Core i5" 3.3 27-Inch Aluminum (Retina 5K, Late 2015/Skylake) features a 14-nm "Skylake" Quad Core 3.3 GHz Intel "Core i5" processor (6600) with four independent processor "cores" on a single chip, a 6 MB shared level 3 cache, 8 GB of 1867 MHz LPDDR3 SDRAM (PC3-14900) installed in pairs (two 4 GB modules), a 2 TB "Fusion Drive," and an AMD Radeon R9 M395 graphics processor with 2 GB of dedicated GDDR5 memory. It also has a built-in "FaceTime HD" webcam and stereo speakers.

This model has a 27" 5120x2880 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 5K" display. 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 2 ports, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n compatible), and Bluetooth 4.0.

Compared to its predecessor, this model essentially has the same external enclosure, but it has a higher quality DCI-P3 "Retina 5K" display with a wider color gamut as well as a more advanced architecture and graphics architecture.

The "Late 2015" iMac models shipped with a compact aluminum Apple Magic Keyboard and the choice of either a multi-touch "Magic Mouse 2" or a traditional wired Apple mouse. For an additional US$50, one also could upgrade from the Magic Mouse 2 to the "Magic Trackpad 2," which provides multi-touch and pressure-sensitive "Force Touch" capabilities.
