The production of a sequel typically implies that the original creation is worth revisiting. However, considering that the original Phenom was the hardware version of Ishtar, many enthusiasts didn't think Phenom deserved to be revisited.
AMD certainly thinks it does-and it hopes Phenom II is Star Trek II: The Wrath of Kahn to Phenom's Star Trek: The Motion Picture. And why shouldn't AMD be able to pull off a reversal of fortune? Phenom II isn't just Phenom joined by a Roman numeral-it's a die shrink with a boatload of additional cache and an improved core. In short, AMD hopes to erase memories of the original Phenom and put smiles on the faces of disappointed overclockers with its reimagined Phenom II chip.
