40nm vs 60nm Power

Hello, I had been under the assumption that a 40nm device will consume less power than a 60nm device given the same code. I tried that with an Arria II GX (40nm) and a Cyclone IV GX (60nm) and...

Reduction of power with process shrinkage is a general trend, but it's neither automatic or guaranteed.

Leakage (static power) can sometimes increase.

Dynamic power reduction usually comes via voltage reduction, with is not the case: both Cyclone IV and Arria II are 1.2V VCCINT.

Additionally, the Cyclone family design puts a greater emphasis on power than Arria.
