Generally, it is difficult to imagine the contrast between sensor measurements purely by reading through a spec sheet. The graphic underneath may give you a better sense of the sensor measurements in the G9 and Quattro.

As you can see, the 2 cameras enjoy different megapixel count and different sensor measurements.

Greater resolution will let you crop photos far more aggressively. The newer G9 should have an advantage with regard to sensor innovation.
