I have the Early-2013 Education iMac with the Core i3-3225 and HD graphics 4000. I was thinking of upgrading to the i7-3770S which also uses 4000 graphics and the same socket. I understand the TDP of the processors are different from one another, but they should be using the same logic board as the late 2012 21.5 which shipped with the i7-3770s.
