AMD has launched three new quad-core Phenom X4 processors, including a high-end Black Edition chip aimed at power users and gamers.

The 2.6GHz AMD Phenom X4 9950 Black Edition processors, the 2.0GHz AMD Phenom X4 9350e and the 1.8GHz AMD Phenom X4 9150e processors were released on Tuesday.

"These processors, under the most extreme operation, consume no more than 65 watts, delivering the performance of four independent cores at a low wattage," said AMD. "[They're] ideal for development of small and sleek form factors that can help cut down on energy consumption, take up little space, and operate with low noise."

In April, AMD released three new triple-core Phenom processors, continuing what has been a new product push for the chipmaker this year.

Jim McGregor, an analyst at In-Stat, said in an earlier interview, that simply shipping new products is a good step for a company that staggered dramatically in 2007 and was forced to delay product releases.

"They're rounding out their product portfolio," he said. "The biggest thing is having a dual core, a triple core and a quad core. They've got different performance, frequency and price ranges. It's very important they're coming out with new product."
