Table 4.28 Intel 5x Chipsets for Socket LGA1156 Core i Series Processors
Intel 6x Series Chipsets
The Intel 6x series of chipsets is designed to support the 2 nd generation Core i Series pro-
cessors (code-named Sandy Bridge). These chipsets are similar to the 5x series, with the
main differences being faster transfer rates on several of the interfaces and support for
newer processors. The first chipsets in the 6x series were introduced in January 2011.

Bridge (that is, memory controller, optional graphics) has been integrated into the pro-
cessor.
Figure 4.25 shows the block diagram of a system with a socket LGA1155 2 nd generation
Core i Series processor on a motherboard with a P67 chipset. In the diagram, you can see
that the functionality of the North Bridge is now part of the CPU, reducing the chipset to
a single South Bridge (now called PCH) component.
