Apple iMac A1312 Late 2009 i7 860 2.8GHz 8GB 2TB 27" | B-Grade 3mth Wty

The iMac "Core i7" 2.8 27-Inch (Late 2009) originally was offered as a "build-to-order" configuration of the iMac "Core i5" 2.66 27-Inch (Late 2009), but it later was offered as a standard configuration, as well.Other than processor, these two models are identical. The iMac "Core i7" 2.8 27-Inch Aluminum (Late 2009) is powered by a 2.8 GHz Quad Core Intel "Core i7" I7-860 (Lynnfield/Nehalem) processor with a dedicated 256k level 2 cache for each core and an 8 MB shared level 3 cache. By default, it is configured with 4 GB of RAM (1066 MHz PC3-8500 DDR3 SDRAM), a 1 TB (7200 RPM) hard drive, a vertically-mounted slot-loading DVDR DL "SuperDrive", and ATI Radeon HD 4850 graphics with 512 MB of dedicated GDDR3 memory.

It also has a built-in iSight video camera and built-in stereo speakers underneath the 27" glossy 16:9 LED-backlit TFT Active Matrix LCD (2560x1440 native) display "with IPS technology". Connectivity includes four USB 2.0 ports, a Firewire "800" port, built-in AirPort Extreme, and Gigabit Ethernet, as well as a Mini DisplayPort, which supports an external display up to 30" (2560x1600). This model also "supports input from external DisplayPort sources" with adapters, so it can be used as an external display for DisplayPort-equipped devices as well as a computer. The "Late 2009" iMac line looks similar to earlier Aluminum iMac models but have an "edge-to-edge" glass design and a "seamless all aluminum enclosure" (previous aluminum models have a modest aluminum border around the display and a plastic back).

Externally, the displays are enhanced with LED-backlighting and "IPS technology" for improved quality, and internally, each has four RAM slots supporting up to 16 GB of RAM (rather than two slots and 8 GB of RAM for earlier models). All "Late 2009" models also include an SD Card slot and redesigned speakers that promise "louder, clearer sound with better bass response and less distortion".
