Normally, it can be tough to visualize the gap between sensor sizing just by reading a spec sheet. The visual below might give you a much better sense of the sensor measurements in the G3 and H400.

As you can see, both the cameras provide different resolutions and different sensor sizing. The G3 having a larger sensor is going to make shooting shallow DOF easier and the Sony H400 will offer extra detail using its extra 4 Megapixels. Greater resolution will also help you crop photos more aggressively. The older G3 is going to be behind with regard to sensor innovation.
