The iMac “Core i5” 2.7 21.5-Inch Aluminium (Late 2013) features Quad Core 2.7 GHz Intel “Core i5” (4570R) processor with four independent processor cores on a single chip, a, 8 GB of 1600 MHz DDR3 SDRAM, a 1 TB hard drive, and an “integrated” Intel Iris Pro 5200 graphics processor with 128 MB of “Crystalwell” embedded DRAM (and shared system memory).
It also has a built-in “”FaceTime HD”” webcam and stereo speakers but lacks an optical drive.
This model has a 21.5″ 1920×1080 LED-backlit 16:9 widescreen IPS display with the “cover glass fully laminated to the LCD and anti-reflective coating.”
The rear of the case is aluminium 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 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 much more efficient “Fourth Generation” processor and architecture, as well as faster graphics, faster Wi-Fi, and the option of faster storage.
The “Late 2013” iMac models shipped with an Apple Wired Keyboard & Mouse.
