IMAC 2011 I5

Apple iMac "Core i5" 2.5 21.5" (Mid-2011) Specs Identifiers: Mid-2011 - MC309LL/A - iMac12,1 - A1311 - 2428 All iMac Models | All 2011 Models | Dynamically Compare This Mac to Others Apple iMac Intel AluminumThe iMac "Core i5" 2.5 21.5-Inch Aluminum (Mid-2011) is powered by a Quad Core 2.5 GHz Intel "Core i5" I5-2400S (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. By default, it is configured with 4 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), a 500 GB (7200 RPM) hard drive, a vertically-mounted slot-loading DVD±R DL "SuperDrive", and AMD Radeon HD 6750M graphics with 512 MB of dedicated GDDR5 memory. It also has a built-in "FaceTime HD" video camera and built-in stereo speakers underneath the 21.5" glossy 16:9 LED-backlit TFT Active Matrix LCD (1920x1080 native) display "with IPS technology". Connectivity includes four USB 2.0 ports, a Firewire "800" port, built-in AirPort Extreme, Gigabit Ethernet, and an SDXC card slot as well as a single "Thunderbolt" port that is backwards compatible with Mini DisplayPort and, likewise, supports an external display up to 30" (2560x1600). Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions. Externally, the "Mid-2011" iMac line uses the same "edge-to-edge" glass design and "seamless all aluminum enclosure" as the "Mid-2010" models that came before them. Internally, however, the "Mid-2011" line is equipped with faster processors and faster graphics processors, as well as the aforementioned external improvements of a higher resolution (and wider angle) webcam and Thunderbolt port. The "Mid-2011" iMac models included a compact aluminum Apple Wireless Keyboard and the choice of either a multi-touch "Magic Mouse" or a multi-touch "Magic Trackpad" that "enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos" just like on Apple notebooks from the same era. An aluminum remote was offered for an additional US$19, too. Also see: What are the differences between the "Mid-2011" Aluminum iMac models?

Each core has a dedicated 256k level 2 cache and all processor cores share a single 6 MB level 3 cache It also supports Turbo Boost 2.0 (up to 3.3 GHz) -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores).
