Often, it is difficult to visualise the difference between sensor measurements only by reading through technical specs. The graphic here will help provide you a greater sense of the sensor measurements in the K-3 and SD14.

As you have seen, each of the cameras offer the same exact sensor sizing albeit not the same resolution. You should expect the Pentax K-3 to give greater detail utilizing its extra 19MP. Higher resolution can also let you crop pictures a little more aggressively. The fresher K-3 will have an advantage when it comes to sensor tech.
