line diverged from its line of desktop processors, which at the time was using the Pentium branding.
The divergence was implemented by using different sockets; since then, the sockets for Xeon chips have tended to remain constant across several generations of implementation.
The chipsets contain a 'memory controller hub' and an 'I/O controller hub', which tend to be called 'north bridge' and 'south bridge' respectively. The memory controller hub connects to the processors, memory, high-speed I/O such as PCI Express, and to the I/O controller hub by a proprietary link. The I/O controller hub, on the other hand, connects to lower-speed I/O, such as SATA, PCI, USB, and Ethernet.
P6-based Xeon chipsets
Dual processor P6-based Xeon chipsets
Intel's initial preferred chipset for Pentium III Xeon was the 840.
Four processor P6-based Xeon chipsets
The Pentium III Xeon bus protocol allowed four processors on the same bus, so the 440GX AGPset could be used in four-CPU systems; the limit of 2 GB of main memory remained. These support

There was also the 450NX PCIset, which consisted of several chips: a single 82451NX Memory and IO Bridge Controller roughly analogous to the North Bridge, up to two 82454NX PCI Expander Bridges which converted the protocol used by 451NX to two 32-bit PCI33 or one 64-bit PCI33 bus, along with up to two memory cards each equipped with one 82452NX RAS/CAS Generator chip and two 82453NX Data Path Multiplexer chips. It supported PIIX3 and PIIX4E south bridges, and EDO DRAM.

It supported up to 8 Pentium III Xeon processors on two busses and maintained cache coherency between them. Profusion supported up to 32 GB of memory. It saw some limited competition from the NEC Aqua II chipset.

Note that the 82870P2 chips of E7500, E7501 and E7505 were initially designed for the Intel 870 chipset for Itanium 2, and that the summary page of the E7320 datasheet incorrectly claims three PCI Express interfaces.

As Intel didn't have a 4P-capable chipset for NetBurst-based Xeons until 2005, for three years ServerWorks GC-HE served as the de facto standard MP chipset, even being used in Intel's own motherboards (SPSH4 and SRSH4).
