Would this turn out to be correct AMD has moved the launched forward and will launch it earlier than we previously expected. As you perhaps know Phenom II X6 is expected to debut at 2.8GHz and sport a new turbo technology for increasing the clock frequency with single cores when the other are idle.
AMD hasn’t commented on the story, but a launch on April 26th fits perfectly with the launch of AMD’s coming 8 series chpisets.
