iMac Core i7 / 3.1 21.5-Inch (Late 2012) BTO/CTO

The iMac Core i7 / 3.1 with 21.5-inch screen (late 2012) is the built-to-order iteration of iMac Core i5 3.1 with 21.5-inch with the top class quad core processor – Intel Core-i7 Ivy Bridge. This is the all-in-one desktop computer in an even slimmer all-aluminum unibody casing behind the 21.5” LED-backlit IPS screen with cover glass fully laminated to the LCD and anti-reflective coating. The body depth at its thinnest has 5 mm, though there’s a certain bulge in the center of the back panel. The computer is mounted on an aluminum stand with a slightly tapered foot and an adjusting hinge. The iMac Core i7 3.1 21.5-inch (late 2012) features a quad core 3.1 GHz Intel Core i7 I7-3770S processor (Ivy Bridge), with four independent processor cores on a single chip, DMI system bus and an integrated graphics core, 8 GB of RAM, a 1TB GB (5400 RPM) hard drive or an optional 1TB Fusion drive, an SD memory slot card reader, Nvidia GeForce GT 650M graphics with 512 MB of shared memory, a built-in FaceTime HD webcam and stereo speakers, as well as a “Thunderbolt” port and 4 USB 3.0 ports. It also has built-in AirPort Extreme (802.11g) and Bluetooth 4.0. The cooling system is CPU controlled and the in-built speakers are mounted beneath the 21.5” screen for the clearer less distorted sound to bounce off the desk or other surface. The speakers’ grills also work as the vent ones. The iMac Core i5 3.1 21.5-inch (late 2012) is shipped with a compact aluminum Apple Wireless Keyboard and either with a “Magic Mouse” or a multi-touch Magic Trackpad.

  • Ivy Bridge processors support more RAM and the latest video codecs; they are capable of 4K video playback. But enhanced performance means enhanced temperature. The Ivy Bridge processors are 10% hotter than the Sandy Bridge ones. This issue is only growing when it comes to overclocking. But, the Intel processors with S-letter in their specs aren’t meant for overclocking originally. See details in Our Guide Book on Intel.
