Come on people, either these guys have a very bad PR or this is a scam. If you think anyone not IBM, Intel or another big player can deliver one chip that can use up to 300W in power, you're delusional. And even them would never do such thing if not for experimental purposes (if even viable for that).
I don't know why they would go for ONE GIANT CHIP rather then breaking it up into smaller ones to dissipate heat better, there wouldn't be any loss in performance.
