Q on N-class processor bus

[Ed Lawrence_1]

Does the N-class have some sort of chipset or switch to split the processor bus into groups of 4 or 2. The block diagram sort of indicates this is so. Can anyone verify? Is this documented anywhere?

[Zygmunt Krawczyk · Accepted solution]

Yes, N-class has actually two processor/memory buses. The buses act as I/O buses also. Each bus has 4 CPU sockets and 6 PCI slots.
