In many cases, it is very tough to see the contrast in sensor measurements purely by seeing technical specs. The visual below may provide you a clearer sense of the sensor dimensions in the Efina and W810.

As you have seen, each of the cameras have got the exact same sensor measurements albeit not the same megapixels. You can expect the Sony W810 to produce more detail as a result of its extra 6 Megapixels. Higher resolution will also make it easier to crop shots much more aggressively. The older Efina will be behind when it comes to sensor innovation.
