More often than not, it can be hard to visualize the difference between sensor sizing only by reading specs. The photograph here might provide you a better sense of the sensor sizing in the 20D and A810.

As you can plainly see, the 2 cameras come with different megapixels and different sensor sizing. The 20D having a bigger sensor is going to make achieving bokeh easier and the Canon A810 will offer greater detail using its extra 8MP. Higher resolution will allow you to crop pictures a good deal more aggressively. The older 20D is going to be disadvantaged in sensor tech.
