Often, it's hard to envision the difference between sensor measurements merely by reading a spec sheet. The visual underneath might provide you a more clear sense of the sensor measurements in the Q and RX10 III.

Clearly, the two cameras enjoy different megapixels and different sensor measurements.

Higher resolution will enable you to crop pictures far more aggressively. The older Q is going to be disadvantaged with regard to sensor technology.
