    What runs faster/more efficient?

      I have AMD Athlon 2 cpu.

       

      • 32-bit application under 64-bit OS 

      OR

      • the same 32-bit app under 32-bit OS?

      To be more specific - I wonder if the cpu emulates 32-bit environment for 32-bit OS more efficiently than

       

      64-bit OS emulates compatibility mode for the same 32-bit app ?
