AMD cuts to the core with 'Bulldozer' Opterons

[JF-AMD]

So, rev. x0 means first silicon = final silicon?

Not necessarily. There are major and minor steppings and sub steppings below that.

Istanbul is D0, for instance, but Shanghai was C3 if I remember correctly. Sometimes you launch with x1 and do a stepping to x2 in midlife. You can't tell final silicon based on the revs.
