This is pretty typical.

Most motherboard "northbridges" are only glorified hypertransport (or QPI on the Intel side) to PCI-E buses, with the southbrdige connected to it via a modified PCI-E link.

I find that hard to believe, since every generation of AMD CPU since the original Athlon 64 and Opterons released in 2003 has had an integrated Northbridge.

There no real difference in what the Bulldozer NB does than what the Phenom NB, or Core i7 NB does, and I am at a loss as to why anyone would think there was.

Thank you for filling me in on this. I do not understand what is hard to believe. I never said I was an expert on CPU/PC design, I was asking questions in an effort to expand my knowledge on the matter.

Sorry for the assumption, it's just that most people interested enough to look up presentation slides on platform architecture have stumbled across the less obscure stuff many times already.

I appreciate the desire to educate one's self and do not mean to discourage it.

That image just shows that SB-E is very nearly double everything in a current SB (except the IGP which is gone).

You can see the rough locations of the various components: 8 cores, nearly double the L3 cache, more memory controllers, etc. The architecture is not that different.

You can compare by looking at a die shot.
