Oftentimes, it can be tough to see the contrast between sensor measurements purely by looking at technical specs. The visual underneath should give you a far better sense of the sensor measurements in the P70 and RX1.

As you have seen, both of the cameras enjoy different megapixels and different sensor measurements. The P70 with its tinier sensor will make achieving bokeh trickier and the Sony RX1 will give more detail having an extra 12 Megapixels. Higher resolution will let you crop shots far more aggressively. The older P70 is going to be behind in sensor tech.
