Often, it is very difficult to visualize the gap in sensor sizing simply by going through a spec sheet. The visual below should provide you a much better sense of the sensor sizing in the SD15 and W810.

Clearly, the two cameras enjoy different megapixels and different sensor sizing. The SD15 having a bigger sensor is going to make achieving shallower depth of field simpler and the Sony W810 will provide extra detail because of its extra 15MP. Higher resolution will make it easier to crop photographs far more aggressively. The older SD15 will be behind with regard to sensor innovation.
