Note
PCI 2.1 supports concurrent PCI operations.
For the Celeron and Pentium II/III motherboards, Intel offered the chipsets in
Table 4.14
.
4xx series chipsets incorporate a North/South Bridge architecture, whereas 8xx series
chipsets support the newer and faster hub architecture. P6/P7 (Pentium III/Celeron, Penti-
um 4, and Xeon) processor chipsets using hub architecture are shown in
Table 4.15
.

Note
Pentium Pro, Celeron, and Pentium II/III CPUs have their secondary caches integrated into
the CPU package. Therefore, cache characteristics for these machines are not dependent on
the chipset but are quite dependent on the processor.
Up until the release of the single-chip 6x series, most Intel chipsets were designed as
a two-part system, using a North Bridge (MCH or GMCH in hub-based designs) and
a South Bridge (ICH in hub-based designs) component. Often the same South Bridge
or ICH component can be used with several different North Bridge (MCH or GMCH)
chipsets.

shows a list of all the Intel South Bridge components used with
