AMD introdes three new quad-core Phenom X4 processors. One of the processors, the new 2.6GHz Phenom X4 9950 Black Edition, is AMD's latest flagship desktop CPU. The other two, however, are somewhat surprising "green", low-power quad-cores dubbed the Phenom X4 9350e (2.0GHz) and Phenom X4 9150e (1.8GHz).

With its Black Edition branding, it should be obvious to the power user among you that the Phenom X4 9950 BE is targeted squarely at enthusiasts and overclockers. But the audience for the Phenom X4 9350e and Phenom X4 9150e processors is a little harder to quantify.
