Normally, it is very tough to imagine the gap in sensor dimensions merely by seeing a spec sheet. The picture below should provide you a much better sense of the sensor measurements in the K-x and A580.

Clearly, both of the cameras feature the identical sensor size albeit different megapixels. You should expect the Sony A580 to produce greater detail because of its extra 4MP. Higher resolution will let you crop shots way more aggressively. The more aged K-x will be behind in sensor innovation.
