The 3.3 is a standalone core while the 7.2 comes with the Quartus II. I believe some timing numbers and bug fixes are done in the 7.2 and also 7.2 might support more devices. The interface should be the same. 


The 7.2 also comes with a high performance one which uses the Altmemphy. That is totally different than the 3.3 version.
