If anyone has been keeping up with the nightmare that has become the Barcelona launch, this article from DailyTech may help shed some light on some of the controversy surrounding the launch.

At first, Dave Graham over at AMD Zone stated that the B1 chips had issues concerning the North Bridge, and that the BA stepping would be used in the retail versions.

DailyTech confirms this, but then it becomes even more confusing.

In his article, Kubicki alludes that the chips used in Monday's launch were B1 stepping, but then also states in the same article that they used B2 stepping in the preview aswell.

Apparently, the 2.5ghz parts use the B2 stepping, and are supposedly errata free.

Yet, both the Anandtech and Tech-Report preview/review seemed to have some inconsistencies in the K10's performance.

So now, I'm left wondering whether Anandtech and Tech-Report really did have B2 stepping chips, or if the B2 stepping chips also have some weird issues that would also affect performance one way or another.
