Panasonic GX8 has a
20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Canon G1 X has a
14.0MP 1.5-inch (18.7 x 14 mm ) sized CMOS sensor and features Digic 5 processor.
Panasonic GX8's sensor provides 6MP more than Canon G1 X's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the GX8 and G1 X sensor size comparison.
As seen above, Canon G1 X has a 1.2x Larger sensor area than Panasonic GX8. 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.
