As you can see, both of those cameras provide the same sensor dimensions but different resolution. You should anticipate the Canon 7D to deliver extra detail utilizing its extra 10 Megapixels. Greater resolution will also let you crop pics more aggressively. The more aged 20D is going to be disadvantaged when it comes to sensor tech.
