Usually, it's hard to envision the difference between sensor measurements just by reading specs. The photograph here should provide you a more clear sense of the sensor measurements in the SZ-10 and K20D.

All in all, both of those cameras posses different resolutions and different sensor measurements. The SZ-10 due to its tinier sensor will make shooting shallow depth of field tougher and the Pentax K20D will offer you greater detail utilizing its extra 1MP. Greater resolution can also make it easier to crop images somewhat more aggressively. The more modern SZ-10 is going to have a benefit when it comes to sensor technology.
