More often than not, it's difficult to visualise the difference in sensor sizes just by seeing a spec sheet. The pic here will help provide you a far better sense of the sensor sizes in the TX7 and A58.

Clearly, both of the cameras have different megapixel count and different sensor sizes. The TX7 due to its smaller sensor will make shooting shallower DOF harder and the Sony A58 will show extra detail as a result of its extra 10MP. Greater resolution can also make it easier to crop images a bit more aggressively. The more aged TX7 will be behind in sensor technology.
