Generally, it can be difficult to visualize the contrast in sensor measurements only by researching specs. The visual underneath will help offer you a much better sense of the sensor sizes in the E90 and RX10 III.

All in all, each of these cameras offer different megapixels and different sensor measurements. The E90 because of its smaller sensor is going to make getting shallower DOF more difficult and the Sony RX10 III will result in more detail as a result of its extra 10MP. Higher resolution will also let you crop photographs a little more aggressively. The older E90 will be behind when it comes to sensor innovation.
