Canon G1 X has a
14.0MP 1.5-inch (18.7 x 14 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, Canon G1 X II has a
13.0MP 1.5-inch (18.7 x 14 mm ) sized CMOS sensor and features Digic 6 processor.
Below you can see the G1 X and G1 X MII sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G1 X and Canon G1 X II Cameras
Canon G1 X and Canon G1 X II have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon G1 X II has 9% larger pixel area (20.17µm 2 vs 18.44µm 2 ) compared to Canon G1 X, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon G1 X and Canon G1 X II sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, G1 X has scored 60, 2 points higher than G1 X MII.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon G1 X
or the
Canon G1 X II ,
including hyperfocal distance.
