Normally, it is very tough to visualize the gap in sensor measurements simply by checking out technical specs. The visual here might give you a far better sense of the sensor sizes in the 6020 and A57.

As you can tell, each of these cameras posses different resolutions and different sensor measurements. The 6020 with its smaller sensor is going to make achieving shallow DOF more difficult and the Sony A57 will provide more detail because of its extra 3 Megapixels. Greater resolution can also allow you to crop photos somewhat more aggressively. The older 6020 will be behind when it comes to sensor technology.
