Edition). To support these new processors as well as Socket 775 Pentium 4 processors
with HT Technology, Intel released the 945, 955, and 975 chipsets.
Because of the greater performance needed to support these high-speed technologies, the
9xx-series chipsets use a faster hub architecture than what was used by the 8xx-series
chipsets. The new interconnect design, known as DMI, runs at 1GBps in each direction.
Table 4.20
lists the 9xx-series chipsets for the Pentium 4;
Table 4.21
lists the 9xx-series
chipsets for the Core 2, Pentium D, and Pentium Extreme Edition (they also support the
Pentium 4); and
Table 4.22
lists the ICH6 and ICH7 families of I/O controller hub chips
used with 9xx-series chipsets.
