More often than not, it is very hard to see the difference in sensor measurements simply by checking out technical specs. The visual below may provide you a greater sense of the sensor dimensions in the E-5 and K-5 IIs.

As you have seen, each of the cameras have got different megapixel count and different sensor measurements. The E-5 having a smaller sensor will make achieving shallower depth of field more challenging and the Pentax K-5 IIs will show extra detail with its extra 4MP. Higher resolution will enable you to crop pictures much more aggressively. The older E-5 will be disadvantaged with regard to sensor tech.
