Clearly, both of those cameras posses different megapixels and different sensor sizes. The TX55 featuring a smaller sensor is going to make getting shallower DOF more difficult and the Sony A99 will produce more detail utilizing its extra 8 Megapixels. Greater resolution can also enable you to crop photos somewhat more aggressively. The more aged TX55 will be disadvantaged in sensor technology.
