Sony a5100 vs YI M1 Sensor Comparison

Normally, its difficult to visualize the gap in sensor dimensions simply by looking through technical specs. The pic below will give you a far better sense of the sensor dimensions in the a5100 and M1.

As you can tell, both of these cameras enjoy different megapixel count and different sensor dimensions. The a5100 featuring a larger sensor is going to make shooting shallower DOF less difficult and the Sony a5100 will result in extra detail as a result of its extra 4 Megapixels. Greater resolution will also allow you to crop pics far more aggressively. The more aged a5100 will be disadvantaged when it comes to sensor technology.
