Fujifilm X10 has a
12.0MP 2/3-inch (8.8 x 6.6 mm ) sized CMOS X-TRANS I sensor and features EXR processor. On the other hand, Ricoh GR II has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor and features GR Engine V processor.
Below you can see the X10 and GR II sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm X10 and Ricoh GR II Cameras
As seen above, Ricoh GR II has a 6.4x Larger sensor area than Fujifilm X10. 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. Fujifilm X10 and Ricoh GR II sensors have been tested by DxO and the results show that GR II has a better overall score of 80, 30 points higher compared to X10's score of 50.

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
Fujifilm X10
or the
Ricoh GR II ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(2/3-inch versus APS-C),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
