As you can tell, both of the cameras have the same sensor dimensions albeit different MP. You should expect the Pentax K-3 III to render more detail as a result of its extra 20 Megapixels. Higher resolution will also allow you to crop pictures a bit more aggressively. The more aged D70 will be disadvantaged with regard to sensor technology.
