Both Sony A6000 and Sony A6600 have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the A6000 and A6600 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6000 and Sony A6600 Cameras
Sony A6000 and Sony A6600 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.

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 A6000
or the
Sony A6600 ,
including hyperfocal distance.
