Quite often, it is very difficult to see the gap between sensor measurements only by reading a spec sheet. The visual underneath should provide you a much better sense of the sensor sizes in the CX3 and SD9.

As you can see, each of the cameras offer different megapixels and different sensor measurements. The CX3 due to its tinier sensor will make getting shallower depth of field more difficult and the Ricoh CX3 will deliver more detail due to its extra 7 Megapixels. Greater resolution will also let you crop photos a little more aggressively. The more modern CX3 is going to have a benefit when it comes to sensor tech.
