Panasonic S5 has a 24.0MP Full frame (35.6 x 23.8 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Canon G3 X has a 20.0MP 1' (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features DIGIC 6 processor.
Another difference between these two cameras is that Panasonic S5's sensor lacks 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 moire occurring in certain scenes.
Below you can see the S5 and G3 X sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic S5 and Canon G3 X Cameras
As seen above, Panasonic S5 has a 7.3x Larger sensor area than Canon G3 X. 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.
