Generally, it can be difficult to visualise the contrast between sensor measurements simply by reading through technical specs. The visual here will offer you a better sense of the sensor sizes in the I-10 and A77 II.

As you have seen, both cameras have got different megapixel count and different sensor measurements. The I-10 with its tinier sensor will make shooting shallower depth of field more challenging and the Sony A77 II will give you extra detail because of its extra 12MP. Higher resolution can also allow you to crop photographs much more aggressively. The older I-10 is going to be disadvantaged in sensor innovation.
