More often than not, it is very hard to envision the contrast in sensor sizes purely by seeing a spec sheet. The pic below should provide you a stronger sense of the sensor sizing in the SX620 HS and A7.

As you can see, both of the cameras provide different megapixels and different sensor sizes. The SX620 HS with its smaller sensor will make achieving shallow DOF harder and the Sony A7 will produce more detail using its extra 4 Megapixels. Higher resolution will also let you crop shots more aggressively. The younger SX620 HS is going to have an edge in sensor innovation.
