Normally, it is very tough to imagine the difference between sensor measurements merely by checking specs. The graphic below might offer you a stronger sense of the sensor measurements in the E-330 and K-500.

As you can plainly see, the 2 cameras have different megapixel count and different sensor measurements. The E-330 with its tinier sensor is going to make shooting bokeh more challenging and the Pentax K-500 will resolve more detail using its extra 9MP. Higher resolution will enable you to crop pictures a bit more aggressively. The older E-330 is going to be behind with regard to sensor tech.
