I have seen that the K-P has 800k ISO and in the max range of the K50/K70/K3-II (51200) the pics look better, much better.
The K3-II has a more advanced noise reduction, so it's high ISO pics look better than that of the K50 BUT as far as I know it's the last Pentax model that comes with a Pentax sensor. The K-P already has the Sony CMOS sensor and the next generation of that will be in the K3-III
From my experience between my K-30 and K-3, the K-30 (same camera internally as the K-50) is MUCH better regarding high ISO shooting all the way to 12,800 ISO. Same sensor size, bigger pixels = less noise.
The K-3 controls noise well, but the images aren't nearly as clean as those from the K-30/50 16 MP sensor, at least from my results shooting both cameras over the years.
