Clearly, both cameras have got different megapixel count and different sensor measurements. The SD10 due to its smaller sensor will make achieving bokeh harder and the Sony A7R II will provide you with more detail due to its extra 39MP. Greater resolution can also let you crop photos much more aggressively. The older SD10 will be behind with regard to sensor tech.
