Normally, its difficult to visualize the gap in sensor measurements only by checking out technical specs. The visual underneath may provide you a much better sense of the sensor sizes in the A7S and A580.

As you have seen, both of the cameras have got different megapixels and different sensor measurements. The A7S due to its bigger sensor is going to make shooting shallow DOF less difficult and the Sony A580 will show more detail having its extra 4MP. Higher resolution will enable you to crop shots much more aggressively. The younger A7S should have an edge with regard to sensor technology.
