Normally, it's difficult to visualise the difference in sensor measurements simply by viewing technical specs. The photograph below should provide you a much better sense of the sensor dimensions in the SD10 and A6400.

As you have seen, both of these cameras have got the exact same sensor measurements albeit not the same megapixels. You should expect the Sony A6400 to result in extra detail due to its extra 21 Megapixels. Higher resolution will also make it easier to crop photographs much more aggressively. The older SD10 will be disadvantaged with regard to sensor innovation.
