These are revised chips, and no-one seems to have noticed. However, in a way, Intel is still milking. These chips are based on a new quad core die that is only 133 mm2 (vs 160 mm2 for the regular die). This die is called "Ivy Bridge-HM-4" and is a new N-0 stepping. It has only 6MB of L3 cache and HD2500 graphics. Intel can now pump out quad core Ivy Bridge chips for OEMs at a die size equivalent to dual core Sandy Bridge last year (131 mm2).
