More often than not, it is tough to visualise the contrast in sensor dimensions just by seeing a spec sheet. The image here will provide you a stronger sense of the sensor sizes in the K100D and A6300.

As you can see, both of the cameras feature the identical sensor size albeit not the same resolution. You should expect the Sony A6300 to provide more detail as a result of its extra 18MP. Higher resolution can also enable you to crop shots way more aggressively. The more aged K100D will be disadvantaged in sensor innovation.
