Plainly, both of the cameras feature different megapixels and different sensor measurements. The E70 featuring a smaller sensor will make achieving shallower depth of field trickier and the Sony RX100 will provide extra detail due to its extra 10 Megapixels. Higher resolution will also help you crop photographs way more aggressively. The older E70 will be behind when it comes to sensor technology.
