Our sources have confirmed that a few Barcelona chips that the company demonstrated at Computex behind the closed doors are B0 revision.
We also learned that B0 can go faster than 1.6 GHz but that it was a very buggy revision. Now our sources are talking about B2 revision that is suppose to save the day and this one is expected any day now.
The same people also indicated that Barcelona will either be the best thing that even happened to AMD or it will be doomed to be the next Netburst. Unfortunately it looks more like the later one, at least from this perspective.
