iMac Late 2013

The iMac "Core i5" 2.9 21.5-Inch Aluminum (Late 2013/Haswell) is built with a 22 nm "Haswell" Quad Core 2.9 GHz Intel "Core i5" (4570S) processor. This CPU contains four independent cores on a single chip, a 6 MB shared level 3 cache, and is paired with 8 GB of 1600 MHz DDR3 SDRAM (which is not meant to be upgraded after purchase). It includes a 1 TB (5400 RPM) hard drive and a NVIDIA GeForce GT 750M graphics processor with 1 GB of dedicated GDDR5 memory. A "FaceTime HD" webcam and stereo speakers are integrated, but an optical drive is not included.

This model has a 21.5" 1920x1080 LED-backlit 16:9 widescreen IPS display with "cover glass fully laminated to the LCD and anti-reflective coating." Its aluminum rear case is thicker in the middle and tapers to a razor-thin 5 mm at the edges.

Connectivity options consist of four USB 3.0 ports, dual Thunderbolt ports, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n compatible), and Bluetooth 4.0.

In comparison with its predecessor, this model has a virtually identical external case but boasts a much more efficient "Fourth Generation" processor and architecture, as well as faster graphics, faster Wi-Fi, and the availability of faster storage options.

The "Late 2013" iMac models came with a compact aluminum Apple Wireless Keyboard and a choice of a multi-touch "Magic Mouse," a multi-touch "Magic Trackpad," or a standard wired Apple mouse.

As the top-tier 21.5-inch model, this machine earned high praise for its Haswell quad-core processor and NVIDIA GeForce GT 750M graphics with 1GB of VRAM. The significant boost in graphics performance made it capable of handling more demanding creative tasks and games. The adoption of 802.11ac Wi-Fi was also a major benefit for users seeking a high-speed wireless environment. Although the limitation of non-upgradable RAM remained, its strong baseline performance was enough to compensate, satisfying many power users.
