Could AMD's long delay on Barcelona be worth the wait? Recently, AMD has revised their performance estimates for their upcoming architecture, and are claiming that it will outperform Clovertown by around 40% at any given time. On top of that, they claim that in some areas it'll be as high as 50%. They even claim that on their next release, Intel's highest-performing Quad Core will lack by as much as 20%. Where are they drawing these figures from? They are not releasing specific clock speed figures for the new CPUs.
It's a bit late in the game for AMD to be trying to win on paper announcements, so hopefully they have more to run on than this later in the year.
