Bear in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you use at that moment. Following is the front view dimension comparison of the DP1s vs the RX100 IV.

Looking at size and weight, the portability rating of the DP1s and RX100 IV is 90 and 89 respectively.

Often, its difficult to imagine the gap between sensor sizing merely by looking at technical specs. The photograph below will help provide you a clearer sense of the sensor dimensions in the DP1s and RX100 IV.

As you can tell, each of the cameras offer different megapixel count and different sensor sizing. The DP1s having a bigger sensor is going to make achieving shallower depth of field easier and the Sony RX100 IV will give more detail using its extra 15MP. Higher resolution can also allow you to crop photographs a little more aggressively. The older DP1s is going to be behind when it comes to sensor tech.
