AMD 900 Series Chipsets
AMD's newest chipsets, the 900 series, are designed to support the new FX “Bulldozer”
processors that use the new AM3+ processor socket. These chipsets can also support
Socket AM3 processors when a suitable BIOS is installed.
All 900-series chipsets use the latest HyperTransport version 3.1 interconnect to achieve
a FSB speed of 3.2GTps, and the first three chipsets in the series (see
Table 4.34
)
support
various levels of ATI CrossFire X and NVIDIA SLI for multi-GPU 3D gaming and ren-
dering. See
Table 4.34
for details.
The SB920 and SB950 South Bridge chips include support for up to six SATA 6Gbps
devices, RAID, HD Audio, and four PCIe x1 slots. See
Table 4.35
for details.
