Quite often, its hard to visualise the gap in sensor sizes just by seeing a spec sheet. The picture here should provide you a stronger sense of the sensor dimensions in the SX20 IS and WG-4 GPS.

As you can see, both of those cameras offer the same exact sensor sizing albeit not the same MP. You should expect the Ricoh WG-4 GPS to provide extra detail as a result of its extra 4 Megapixels. Higher resolution will also make it easier to crop shots a little more aggressively. The more aged SX20 IS will be behind when it comes to sensor innovation.
