The iMac "Core i5" 3.5 27-Inch Aluminum (Late 2014/Retina 5K) is equipped with a 22 nm "Haswell" Quad Core 3.5 GHz Intel "Core i5" (4690) processor. This CPU has four independent cores on a single chip, a 6 MB shared level 3 cache, and is paired with 8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) in a dual-module configuration. It includes a 1 TB "Fusion Drive" (comprising a 1 TB hard drive and a 128 GB SSD) and an AMD Radeon R9 M290X graphics processor with 2 GB of dedicated GDDR5 memory. An integrated "FaceTime HD" webcam and stereo speakers are included, but it lacks an optical drive.
This model showcases a 27-inch 5120x2880 LED-backlit 16:9 widescreen IPS display, which Apple branded as "Retina 5K". The aluminum rear housing is thicker at its center and tapers to a slim 5 mm at the edges. Connectivity features four USB 3.0 ports, dual Thunderbolt 2 ports, Gigabit Ethernet, 802.11ac Wi-Fi (backward compatible with 802.11a/b/g/n), and Bluetooth 4.0.
In comparison to the preceding Late 2013 models, this version has a nearly identical external case but offers a much higher-resolution display, a slightly faster processor, a more powerful graphics processor, a "Fusion Drive" as standard, and Thunderbolt 2 support. The "Late 2014" iMacs were shipped with a compact aluminum Apple Wireless Keyboard and the choice of a multi-touch "Magic Mouse," a multi-touch "Magic Trackpad," or a conventional wired Apple mouse.
