Usually, it is hard to visualise the contrast between sensor measurements merely by reading specs. The visual here may give you a far better sense of the sensor dimensions in the K100D S and W650.

As you can plainly see, the 2 cameras provide different resolutions and different sensor measurements. The K100D S having a bigger sensor will make achieving shallow depth of field less difficult and the Sony W650 will deliver extra detail because of its extra 10 Megapixels. Higher resolution can also allow you to crop photographs more aggressively. The older K100D S is going to be disadvantaged in sensor innovation.
