The iMac “Core i5” 2.7 21.5-Inch Aluminum (Late 2013/Haswell) features a 22 nm “Haswell/Crystalwell” Quad Core 2.7 GHz Intel “Core i5” (4570R) processor with four independent processor cores on a single chip, a 4 MB shared level 3 cache, 8 GB of 1600 MHz DDR3 SDRAM, a 1TB 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 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. The “Late 2013” iMac models shipped with a compact aluminum Apple Wireless Keyboard and the choice of either a multi-touch “Magic Mouse,” a multi-touch “Magic Trackpad,” or a traditional wired Apple mouse.

The iMac “Core i5” 2.7 21.5-Inch Aluminum (Late 2012) features a 22 nm Quad Core 2.7 GHz Intel “Core i5” I5-3330S (Ivy Bridge) processor with four independent processor cores on a single chip, a 6 MB shared level 3 cache, 8 GB of 1600 MHz DDR3 SDRAM (which is not intended to be upgraded after purchase), a 1 TB (5400 RPM) hard drive, and a NVIDIA GeForce GT 640M graphics processor with 512 MB 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 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 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, 802.11n, and Bluetooth 4.0.

The iMac “Core i5” 2.7 21.5-Inch Aluminum (Mid-2011) is powered by a Quad Core 2.7 GHz Intel “Core i5” I5-2500S (Sandy Bridge) processor with a dedicated 256k level 2 cache for each core and a 6 MB shared level 3 cache. In lieu of a system bus, it has a “Direct Media Interface” (DMI) that “connects between the processor and chipset” at 5 GT/s.

The 27″ iMac Desktop Computer from Apple is an all-in-one desktop computer with an ultra-slim unibody design. Measuring at just 5mm at its edges, the iMac has 40% less volume than its predecessor. The body of the iMac isn’t the only thing that got thinner. The LCD display is now 5mm thinner, and Apple also removed a 2mm gap between the LCD panel and the glass to save even more space. The 27″ widescreen display features LED backlighting for vibrant, accurate color. With in-plane switching (IPS) technology, the iMac has a wide 178° viewing angle. The screen has a 16:9 aspect ratio and Full HD 2560 x 1440 native resolution, supported by an nVIDIA GeForce GTX 675MX graphics card with 1GB discrete GDDR5 memory.
