Kodak S-1 has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Sony A6500 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz X processor.
Sony A6500's sensor provides 8MP more than Kodak S-1'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 S-1 and A6500 sensor size comparison.

Sensor Size and Resolution Comparison image of Kodak S-1 and Sony A6500 Cameras
As seen above, Sony A6500 has a 1.6x Larger sensor area than Kodak S-1. 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.
