They are exactly the same internal hardware, engine block and heads wise.
The engine internals consist mostly of forged hardware, pistons and rods as well as the crankshaft - the piston assemblies are the same as used in the M133 (ie. AMG A & CLA 45's)
The differences are as already mentioned the dry oil sump system, air intake feed systems and outer exhaust peripherals.

The power/torque output and curve is absolutely governed by ECU programing yes 
There'll also be torque output governing and/or control by the TCU ie. the transmission ecu especially in the case of the AMG GT to control maximum torque "through flow".
