North And South Bridges


Recommended Posts

AMD based systems don't exactly have a separate northbridge/southbridge. In Intel systems, the memory controller is part of the northbridge. In AMD based systems, the memory controller is built into the processor itself. Therefore, the remaining duties of the northbridge get combined with the southbridge to form a single chipset.

 

Granted, there are still separate chips that control some things like audio and secondary SATA controllers, but overall, there is only a single chipset, which is how you refer to that thing under the fan.

no no... the NF3 / NF4 is a combined. via, some sis, and ATI chipsets for the A64's are still split into a north and south bridge.

 

north bridge handles the PCI-E / AGP, integrated video (if it has it), and memory controller (intel only). southbridge handles the PCI bus, drive controllers (unless it's PCI-E SATA2), and other integrated devices attached to the PCI bus.

I was assuming he wanted to know where the "northbridge" was for his Neo2, so it would be correct to say it's combined seeing as how he has a NF3 board.

you'd be 100% correct in that statement. infact it has been on all AMD Nforce's since the NF3
