AMD is expanding its lineup of fledgling Phenom quad-core CPUs with the addition of three new models.

On the performance side, the company is introducing the Phenom 9950 Black Edition. We already talked about this 2.6GHz clocked part here. The 9950 Black Edition should cost $235.

The company has also launched two energy efficient Phenoms, the Phenom X4 9350e clocked at 2GHz, and the 9150e at 1.8GHz. They will be priced $195 and $175, respectively.

We still haven't been able to find the new parts listed in the E.U. and we're not sure about the availability dates or European pricing either, so stay tuned for more.
