Refurbished 27-Inch (Slim, Tapered Edge) Apple IMac "Quad Core i7" 3.5Ghz 8GB Ram 1TB HDD (Late 2013)

The iMac "Core i7" 3.5 27-Inch Aluminum (Late 2013/Haswell) features a 22 nm "Haswell" Quad Core 3.5 GHz Intel "Core i7" (4771) processor with four independent processor cores on a single chip, an 8 MB shared level 3 cache, 8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) installed in pairs (two 4 GB modules), a 1 TB (7200 RPM) hard drive (or a 3 TB "Fusion" Drive for the standard MF125LL/A configuration), and a NVIDIA GeForce GTX 775M graphics processor with 2 GB of dedicated GDDR5 memory. It also has a built-in "FaceTime HD" webcam and stereo speakers, but lacks an optical drive.

This model has a 27" 2560x1440 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 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 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.
