More often than not, it is very hard to visualize the gap in sensor sizing purely by viewing specs. The photograph below will help offer you a far better sense of the sensor dimensions in the E-P3 and HX400V.

All in all, both the cameras have different megapixel count and different sensor sizing. The E-P3 due to its bigger sensor is going to make shooting shallower DOF easier and the Sony HX400V will result in extra detail due to its extra 8MP. Higher resolution can also allow you to crop shots a bit more aggressively. The older E-P3 will be disadvantaged with regard to sensor innovation.
