Looking at dimensions and weight, the portability grade of the E-330 and K-70 is 65 and 62 respectively.

Quite often, its tough to picture the gap between sensor dimensions simply by going over technical specs. The image here may offer you a greater sense of the sensor measurements in the E-330 and K-70.

As you can tell, the two cameras provide different megapixel count and different sensor dimensions. The E-330 due to its tinier sensor is going to make shooting shallower DOF harder and the Pentax K-70 will offer greater detail having its extra 17MP. Greater resolution will help you crop photos more aggressively. The more aged E-330 is going to be disadvantaged when it comes to sensor tech.
