Even if Piledriver is a "Sandy Bridge Killer", the problem will be in the fact that it took them almost 2 years to get it out. Keep in mind, Sandy Bridge has been out for a year at this point, and Piledriver won't be out until the middle/end of this year. Intel is in a great position to counter anything AMD throws at them. I also don't understand why it keeps being speculated whether or not Zambezi was intended to be a "Server CPU" or "Server-Oriented", when they still marketed it as an Enthusiast CPU. You don't compare an FX-8150 to a 990X unless you're trying to say it can compete in that segment, just like you wouldn't compare a Motorcycle to a Car.
