>that Intel does not comment on it's competitors directly because they are afraid of antitrust action.
I don't see the connection. There is no antitrust law I ever heard of that would make it illegal to slam your competition as much as you please. (There are people that claim that Intel keeps AMD around to avoid getting classified as a monopoly and therefore subject to legal restrictions. I think they are wrong.)
Name recognition. You never want to help out your competition by mentioning their name. That's advertising for them. If somebody brings up the competition's name, change the subject to something about your own company. Never let the other name cross your lips.
Respect. If Intel were to mention AMD, it would elevate AMD to being worthy of mention. They don't want to do that. To compare themselves to AMD, would be to lower themselves.
The only time you mention your competiition is if you are in second place or worse. Then you only mention your competition to say how much better than them you are. If somebody asks you a question pointing out the big guy's strength, disregard it and immediately change the subject to something great about yourself. Pepsi used to have a commercial where they claimed 8 out of 10 people preferred Pepsi over Coke in blind taste tests. They showed blindfolded people that always picked Pepsi over Coke. On the label of Kroger yogurt they told you that you got 33% more yogurt than from Dannon. (until Kroger subsequently went to 6 oz cups too.) On generic vitamins they say "Compare to Centrum." Comparing yourself favorably to the leader puts you in the same league.
There was kind of a flap (from AMD partisans) not long ago when an Intel rep responded to a reporter who brought up the Athlon 64, saying it was nothing really new, just the same old same old. That was a mistake, a slip. He should have just ignored the Athlon and switched to something great about the Itannic. The Intel marketing department was probably ballistic over that.
