Clearly, both of those cameras posses different megapixels and different sensor measurements. The SX400 IS having a smaller sensor will make achieving shallower DOF harder and the Canon SX400 IS will provide you with greater detail having an extra 11MP. Greater resolution will enable you to crop images somewhat more aggressively. The newer SX400 IS is going to have an edge when it comes to sensor technology.
