Generally, it is very tough to visualise the gap in sensor measurements merely by viewing a spec sheet. The visual below will provide you a more clear sense of the sensor sizing in the A7 and W550.

As you can see, each of the cameras posses different resolutions and different sensor measurements. The A7 using its larger sensor will make achieving shallow depth of field simpler and the Sony A7 will result in greater detail using its extra 10MP. Greater resolution can also enable you to crop images somewhat more aggressively. The newer A7 is going to have an advantage in sensor technology.
