I have AMD Athlon 2 cpu.

 

• 32-bit application under 64-bit OS 

OR

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

 

picture illustration attached.

 

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 ?
