The 5DS was announced 6 years later than the K20D and that is quite a big difference as far as technology is concerned. Both of these cameras come with the identical body type (Mid-size SLR).

Before delving in to a more detailed comparison, below is a simple view of how the 5DS scores vs the K20D with regard to portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Canon EOS 5DS & Pentax K20D. The whole galleries are provided at Canon 5DS Gallery & Pentax K20D Gallery.

Quite often, it is difficult to visualise the difference between sensor measurements simply by reading through specifications. The photograph here might give you a far better sense of the sensor measurements in the 5DS and K20D.

To sum up, both of these cameras posses different megapixel count and different sensor measurements. The 5DS having a larger sensor will make shooting shallow DOF less difficult and the Canon 5DS will give you more detail with its extra 36 Megapixels. Greater resolution will also let you crop pics somewhat more aggressively. The younger 5DS will have an advantage when it comes to sensor tech.
