Quietly introduced without a press release, the iMac "Core i3" 3.3 21.5-Inch (Early 2013/Education Only) -- which originally only was available for sale to educational institutions -- is powered by a Dual Core 3.3 GHz Intel "Core i3" I3-3225 (Ivy Bridge) processor with a dedicated 256k level 2 cache for each core and a 3 MB shared level 3 cache. It has an "integrated" Intel HD Graphics 4000 graphics processor that shares memory with the system.
