In-Depth Information
Several third-party companies also produced chipsets designed to support P6-class processors,
including ALi Corporation (formerly known as Acer Laboratories), VIA Technologies, and SiS. ALi
(Acer Labs, Inc.) spun off its chipset division in 2003 as ULi Electronics; then ULi was acquired by
NVIDIA in 2006. ALi manufactured a variety of chipsets for the P6-class processors. Most of these
were similar in form and function to the Intel offerings.
Seventh/Eighth-Generation (Pentium 4/D, Core 2, and Core i)
Chipsets
The Pentium 4 and Celeron processors using Socket 423 and those made for Socket 478 are
essentially the same processors with different cache designs and minor internal revisions, so the same
chipset can be used for both processors. The Pentium 4 processor in Socket 775 is different from its
predecessors; consequently, most 9xx-series chipsets support only the Socket 775 version of the
Pentium 4, as well as the newer Core 2 series of processors.
Tables 4.15
and
4.16
show the 8xx-series chipsets Intel made for Pentium 4 and Celeron 4
processors. These chipsets use Intel's hub architecture, providing an interconnect speed of 266MBps
between the MCH/GMCH and the ICH chips.
