As you can tell, both of the cameras have got the exact same sensor measurements albeit not the same megapixels. You should expect the Canon 400D to deliver extra detail with its extra 4MP. Higher resolution will also enable you to crop shots much more aggressively. The more aged 400D is going to be behind when it comes to sensor technology.
