Before the last upgrade of iMac models, several rumors were already indicating the potential use of Intel Core i7, as a Quad Core CPU in an iMac would have been much desired. Unfortunately, as Intel only released a limited number of Quad Core models, its usage was limited not only for Apple but also other manufacturers as high TDP limit its integration in compact enclosure as the iMac. The recent update as then limited to the adoption of SS3 and new graphical chips not necessarily more powerful than the previous ones. however, Core iX CPUs might not be lost forever for the iMac. the web is reporting more and more about the Intel Core i5 which should arrive in couple of months, and the website Xfaster published photos and quick tests.
