Well after readin' all the stuff about BD, my nooby chip expertese tells me that.

IPC will be be improved at the same clocks, than current AMD processors.
It will take less space per core
It will clock higher than the current crop of AMD processors.

It looks like it will be highly competitive in the server market, but behind in the 'gamers' segment (possibly close to matching today's Intels because of clockspeed, but not surpassing it in IPC).

obviously no one will know until it gets leaked.
