Nikon Z6 II has a
25.0MP Full frame (35.9 x 23.9 mm ) sized BSI-CMOS sensor and features Dual Expeed 6 processor. On the other hand, Nikon D3000 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor and features Expeed processor.
Nikon Z6 II's sensor provides 15MP more than Nikon D3000'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 Z6 Mark II and D3000 sensor size comparison.
As seen above, Nikon Z6 II has a 2.3x Larger sensor area than Nikon D3000. 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.
