Well, I haven't read an article on the latest Intel - AMD comparisions - where they really go at each other. But in a secret warehouse on the outskirts of our city I have heard there are people that pit dogs against bears. The outcome of these clandestine encounters is that the bear always loses, but sometimes the bear can kill a dog before they get him. I don't have link for this; just reporting what I heard.
I do know that Tom's Hardware did compare a Barton with a P4 3.0 Gig when the Barton first came out. If it's not on their front page, you might try a search for Barton.
