The A550 was introduced 8 years prior to the RX10 IV and that is quite a big gap as far as technology is concerned. Both of the cameras have different body design with the Sony A550 being a Compact SLR camera and the Sony RX10 IV being a SLR-like (bridge) camera.

Before going straight to a full comparison, here is a simple view of how the A550 matches up vs the RX10 IV in terms of portability, imaging, features and an overall rating.

Normally, it can be difficult to imagine the gap between sensor sizing just by looking at specifications. The graphic here may give you a greater sense of the sensor measurements in the A550 and RX10 IV.

To sum up, each of the cameras have different megapixel count and different sensor sizing. The A550 using its bigger sensor is going to make shooting shallower depth of field less difficult and the Sony RX10 IV will give more detail using its extra 6 Megapixels. Higher resolution will let you crop pictures a bit more aggressively. The older A550 is going to be behind with regard to sensor technology.
