Sony RX100 has a
20.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor . On the other hand, Nikon D3300 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Expeed 4 processor.
One other difference between these two cameras that is worth mentioning is that Nikon D3300's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the RX100 and D3300 sensor size comparison.
As seen above, Nikon D3300 has a 3.2x Larger sensor area than Sony RX100. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Sony RX100 and Nikon D3300 sensors have been tested by DxO and the results show that D3300 has a better overall score of 82, 16 points higher compared to RX100's score of 66.
