Often, it is very hard to imagine the difference in sensor sizing purely by looking through a spec sheet. The photograph below will help give you a much better sense of the sensor sizes in the T90 and A77 II.

Clearly, the 2 cameras have got different megapixels and different sensor sizing. The T90 having a smaller sensor is going to make achieving shallow depth of field harder and the Sony A77 II will provide you with more detail because of its extra 12 Megapixels. Greater resolution will also make it easier to crop photos much more aggressively. The older T90 will be disadvantaged when it comes to sensor technology.
