AMD (Formerly ATI) Chipsets for Athlon 64, Sempron, Phenom
One of the expectations of AMD's acquisition of ATI in 2006 was the release of AMD/ATI chipsets
for AMD processors. Since then, AMD has released several to support the Athlon 64, Sempron, and
Phenom processors. Tables 4.26 through 4.29 summarize the major features of these chipsets, and
Table 4.30 covers the corresponding South Bridge components.
While Intel chipsets are closely tailored to particular Intel processor families, AMD North Bridge
and South Bridge components can be mixed and matched. Thus, you may find motherboards based on
the same North Bridge component to have different features depending upon the South Bridge
component used.
