More often than not, it is difficult to visualize the difference in sensor dimensions purely by looking through a spec sheet. The pic underneath will give you a stronger sense of the sensor measurements in the Q7 and A550.

Clearly, both of those cameras have different megapixels and different sensor dimensions. The Q7 featuring a smaller sensor is going to make getting shallow depth of field harder and the Sony A550 will result in extra detail having its extra 2 Megapixels. Higher resolution will also enable you to crop pictures a bit more aggressively. The younger Q7 provides an edge when it comes to sensor innovation.
