AMD "Piledriver" refresh of Zambezi - info, speculations, test, fans

[undone]

undone and what does it have in common with my comment, I never said BD can't be tweaked .

To me it looks like you'r saying IPC lower than deneb is a failure. But processor design is complicate than we thought.
Even if Zambezi doesn't have those problems I still doubt IPC would increase.

I don't know why you think they planned for BD to have worse IPC than K10
If that was true then why was JF always saying the IPC will increase over K10 and he meant BDv1(bulldozer) not BDv2(piledriver) or BDv3(steamroller) because that was what he heard from the engineers but sadly It wasn't true, simply put BD wasn't what they wanted.

IIRC, 'IPC increase' is due to some simply statements like '33% more cores but 50% increase compare to Thuban'. But they never mentioned anything about the balance between frequency and ipc.

Ok, I wanna end up discussion about BD, if my comment lead to off-topic then sorry.
