Normally, it is difficult to see the difference in sensor measurements only by looking through a spec sheet. The graphic underneath will help give you a much better sense of the sensor dimensions in the K10D and A550.

Clearly, both of those cameras feature the identical sensor size albeit not the same MP. You should expect the Sony A550 to provide you with greater detail having its extra 4 Megapixels. Higher resolution will also help you crop photographs way more aggressively. The older K10D will be behind with regard to sensor innovation.
