The P70 was introduced 6 years earlier than the Q-S1 and that is quite a serious difference as far as technology is concerned. Each of these cameras offer different body type with the Pentax P70 being a Ultracompact camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.

Before delving in to a detailed comparison, below is a quick introduction of how the P70 matches up versus the Q-S1 in terms of portability, imaging, features and an overall grade.

Quite often, it is tough to visualise the gap between sensor measurements purely by going over a spec sheet. The visual here might give you a more clear sense of the sensor sizes in the P70 and Q-S1.

As you can see, the 2 cameras offer the same exact megapixels albeit not the same sensor measurements. The P70 comes with the tinier sensor which is going to make getting shallower depth of field more difficult. The older P70 is going to be behind when it comes to sensor tech.
