More often than not, it is very tough to imagine the gap in sensor measurements just by going through technical specs. The graphic underneath will give you a clearer sense of the sensor sizes in the Q7 and A55.

As you have seen, both the cameras offer different resolutions and different sensor measurements.

Higher resolution can also help you crop pictures a little more aggressively. The younger Q7 provides a benefit in sensor tech.
