AMD's Bobcat and Bulldozer

[-Boris-]

Here we have the reason. Integrated PCI-Express controller.

EDIT: Well obviously not, but that what techpowerup claims.

No,northbridge controller is not PCI-Express controller,K8 already has integrated northbridge controller.

[-Boris-]

No,there is no integrated PCI-Express controller in bulldozer.

No it shouldn't be, if it was, AM3 CPUs wouldn't work in AM3+ either. , another messed up article.
And the serverparts wouldn't fit G34 either.

But what do the mean by NB? It can't be the memory controller (as in K8) since it's mentioned separately.

I know that NB been there since K8, but at that time they meant IMC when they mentioned NB. Now they're mentioned as separate units. What do they mean with NB today if it isn't IMC?

They mentioned IMC and NB as separate units since K10.

They mentioned IMC and NB as separate units since K10.

So what is this NB? What does it do? It isn't the bus interface (HT) since that would make every processor with a bus regarded as a processor with an on-die NB. And it isn't the IMC, what is it then? Source please.

EDIT:
At this point, I do believe BD fits ordinary AM3. And I don't think the PCIe is integrated. But I do have some big questions to sort out first.

this socket compatibility thing is getting more and more confusing, but I know a lot of people buying AM3 now thinking about upgrading to bulldozer, if this is not possible... AMD will piss off (and lose) many customers...
I saw people choosing AM3 instead of i7 just because of the future upgrades...
but anyway, looking at this articles is impossible to be certain about this...
let's wait for some clear statement...

Yeah, now we have three sources claiming that BD won't fit AM3. And one of them claims that it's an integrated PCIe-controller. On top of that we have an AMD slider that mentions the NB separately from the IMC.

Here we have the reason. Integrated PCI-Express controller.

EDIT: Well obviously not, but that what techpowerup claims.

Nope. No integrated PCIe. That would not allow us to use the same sockets.

Nope. No integrated PCIe. That would not allow us to use the same sockets.

That would be G34 and C32, is it AM3 as well?

Sorry, it's an obvious desktop question, but given that old roadmaps says YES, and some sources todays says NO, I just wish you could answer.

JF-AMD pls answer this if possible...

There's "L3 Cache and NB" and "Integrated Northbridge Controller".

The "NB" in "L3 Cache and NB" is the northbridge component found on AMD processors since K8. The "Northbridge Controller" is the IOMMU (what we're used to referring to as northbridge, such as AMD 790FX) integrated into the processor die.

No, the PCIe controler (like 790FX) isn't integrated. So we still don't know what that part is.
There are three NBs on that picture, and only one that truly is a northbridge, and that isn't even labeled as a northbridge, it's labeled as an IMC.
