Generally, it is very difficult to visualise the difference in sensor measurements just by researching specifications. The graphic here will provide you a greater sense of the sensor dimensions in the SD9 and W320.

To sum up, both of the cameras provide different resolutions and different sensor measurements. The SD9 featuring a larger sensor will make shooting shallower DOF less difficult and the Sony W320 will result in more detail due to its extra 11MP. Greater resolution can also enable you to crop pics more aggressively. The older SD9 will be disadvantaged with regard to sensor tech.
