Haddock, I wasn't speaking of the Inquirer in general, but for the author of the particular article. I have seen him post on the Ace's forum, and I've begun to expect very slanted comments from him. I've seen you post on Ace's as well. Maybe you also know the author in question.
As for Opteron, like I have said, I am speaking at the logic level. I don't see why AMD would change the logic in any significant way. This comes from my experience in the field, and the need for engineers to reuse code whenever possible. It looks like Opteron was improved on a circuit level, which you can tell slightly from the die plot. In terms of logic, that goes against the grain for me. It doesn't make much sense.
In terms of the comments from the engineer, I am inclined to believe that the author who wrote the article for the Inquirer either made up the information, or he misunderstood what the engineer was trying to say.
