Generally, it can be hard to visualise the gap between sensor sizes just by going over technical specs. The pic underneath should provide you a far better sense of the sensor measurements in the NX300M and A7R.

As you can tell, both of those cameras provide different megapixel count and different sensor sizes. The NX300M with its tinier sensor will make getting shallow depth of field more difficult and the Sony A7R will offer you extra detail having an extra 16 Megapixels. Higher resolution can also make it easier to crop pictures more aggressively. The more aged NX300M is going to be disadvantaged when it comes to sensor technology.
