The A900 was manufactured 9 years before the M1 which is a fairly big gap as far as camera tech is concerned. Both cameras have different body design with the Sony A900 being a Mid-size SLR camera and the YI M1 being a Rangefinder-style mirrorless camera.

Generally, it is very hard to picture the gap in sensor sizes only by researching technical specs. The pic here may provide you a far better sense of the sensor dimensions in the A900 and M1.

As you can tell, each of these cameras provide different megapixels and different sensor sizes. The A900 because of its larger sensor is going to make achieving shallow DOF easier and the Sony A900 will render extra detail due to its extra 5MP. Greater resolution can also let you crop photos more aggressively. The more aged A900 will be disadvantaged when it comes to sensor innovation.
