Both Sony RX10 III and Panasonic FZ1000 have 1″ sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the RX10 III and FZ1000 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony RX10 III and Panasonic FZ1000 Cameras
Sony RX10 III and Panasonic FZ1000 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.
DxOMark Sensor Scores
Both Sony RX10 III and Panasonic FZ1000 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, RX10 III has scored 70, 6 points higher than FZ1000.

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
Sony RX10 III
or the
Panasonic FZ1000 ,
including hyperfocal distance.
