what's going on with Arria V

Guys, I need some reasonable explanation for this before I shoot an SR to Altera. I'm using Quartus 12.1, the greatest supposedly. I have exactly the same design, written in behavioral code...

Did you get the same size after fitting for each design ?

If your design uses block ram , are you sure that quartus inferred them correctly for arria 5?

If not Quartus may use LEs instead of block ram, leading to long run time and poor lower timing performances.
