How to compare Stratix V vs Xilinx resource

[Altera_Forum]

How to I compare logic resources (logic gates, FFs) for a Stratix V part 5SGXEABN2F45C2 and part 5SGXEA7N2F45C2 versus a Xilinx Virtex7 XC7V2000T?

What exactly do you want to check? easiest thing is just check the percentage usage?

I had been working with Xilinx' Virtex5 FX200T, Virtex6 LX760 and Vitex7 2000T. Without running through any tools, how can I compare the number of FFs and logic gates? For instance, for Virtex5 FX200T there are 122,880 FFs and 196,608 logic cells. How does it measure up to the Stratix V parts above?

From that, it seems straightforward to compare FFs where the 5SGXA7 has 939k which compares to the V6LX760 with 948k FFs. How does one compare the 622k Logic Elements for 5SGXA7 to the 758k Logic Cells for V6LX760? Is there an agreed upon convention to convert to logic gates?
