iMac performance is at an all-time high with new Intel Core processors, powerful graphics, Thunderbolt connectivity, and stunning displays with one billion colors and brightness for vibrant images and razor-sharp text.
The iMac Core i5 2.7 27-Inch Aluminum features a 22 nm Quad Core 3.2 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 27-inch LED-backlit 2560×1440 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.
