AMD Phenom 9600 Black Edition CPU Review
 

The Phenom launch was not without its bright spots. First and foremost
was the fact that the Phenom would be the first true quad core

side came in the form of one heck of an olive branch from AMD, in the
form of a multiplier unlocked “Black Edition” of the Phenom 9600. We
have just such a creature for a review.
