In many cases, it is tough to picture the contrast in sensor sizing purely by seeing a spec sheet. The graphic here should give you a clearer sense of the sensor measurements in the a1 and RX10 III.

Clearly, both cameras have different megapixel count and different sensor sizing. The a1 with its larger sensor is going to make shooting shallow DOF less difficult and the Sony a1 will show greater detail having an extra 30MP. Greater resolution can also make it easier to crop images a bit more aggressively. The more modern a1 provides a benefit when it comes to sensor tech.
