AMD has announced three new processors in its quad-core Phenom X4 range, the new flagship 9950 Black Edition featuring a max TDP of 140 watts with a clock speed of 2.6GHz, and two more energy-efficient chips, the Phenom X4 9350e and Phenom X4 9150e.

The Phenom X4 9950 is now AMDís top-of-the-line processor, offering a slight speed bump over the 2.5GHz Phenom X4 9850 part announced earlier this year. With its Black Edition branding, the new chip is obviously being targeted squarely at enthusiasts / overclockers and itís currently slated to retail at the same $235 price that its predecessor sold for.

The two lesser parts are fundamentally the same as the 9950, with the only difference being that the 9350e and 9150e are locked to a maximum voltage of 1.125v, giving them 2.0GHz and 1.8GHz speeds respectively and a TDP of 65W. AMD is pricing the 9350e at $195 and the 9150e at $175. All three chips are fabbed using a 65nm process and contain 2MB of shared L3 cache and 512KB of L2 per core.
