As you can plainly see, both cameras enjoy the same exact sensor sizing but not the same megapixels. You should expect to see the Sony TX20 to give you more detail because of its extra 2 Megapixels. Greater resolution will also help you crop images far more aggressively. The more aged ST90 is going to be behind with regard to sensor innovation.
