The iMac "Core 2 Duo" 2.93 24-Inch Aluminum (Early 2009) is equipped with a 2.93 GHz Intel "Core 2 Duo" processor, which has two independent cores on a single chip, a 6 MB shared level 2 cache, and a 1066 MHz system bus. It includes 4 GB of RAM (1066 MHz DDR3 SDRAM), a 640 GB (7200 RPM) hard drive, and a vertically-mounted slot-loading DVD±R DL "SuperDrive". The system features NVIDIA GeForce GT 120 graphics with 256 MB of dedicated GDDR3 memory, an integrated iSight video camera, and built-in stereo speakers under the 24" glossy TFT Active Matrix LCD (1920x1200 native) display.
Its connectivity suite consists of four USB 2.0 ports, a Firewire "800" port, built-in AirPort Extreme, and Gigabit Ethernet, as well as a Mini DisplayPort for external display support in "extended desktop" mode.
The iMac "Core 2 Duo" (Early 2009) models are quite like the "Early 2008" models they succeeded, having similar external cases—differentiated only by a "tapered foot"—and the same glass cover that "joins precisely to the aluminum enclosure creating a virtually seamless front surface."
Although clock speeds and configurations are comparable, a few differences are notable: the Firewire "400" port of the Early 2008 models was exchanged for an additional USB 2.0 port on the Early 2009 models, Mini-DVI was upgraded to Mini DisplayPort, and the 2009 models also feature DDR3 memory (rather than DDR2) with twice the official capacity, superior graphics on higher-end configurations like this one, and shipped standard with a smaller keyboard without a numeric keypad.
