Quite often, it can be tough to visualize the difference in sensor measurements simply by seeing a spec sheet. The visual underneath will give you a more clear sense of the sensor dimensions in the K-5 and E90.

As you can see, both the cameras feature different megapixels and different sensor measurements. The K-5 with its bigger sensor is going to make shooting shallow depth of field simpler and the Pentax K-5 will show greater detail having an extra 6MP. Higher resolution will also let you crop pictures way more aggressively. The fresher K-5 should have an edge with regard to sensor technology.
