ATI Chipsets
ATI's original line of chipsets for the Pentium 4 integrated Radeon VE-level 3D graphics,
DVD playback, and dual-display features with high-performance North Bridge and South
Bridgedesigns.ATIuseditshigh-speedA-LinkbustoconnectitsNorthandSouthBridge
chips. These included the ATI IGP 330/340/350/360 series. The Radeon 9x00 IGP family
was ATI's second generation of chipsets for the Pentium 4. The 9x00 IGP North Bridge
chips feature Radeon 9200-level graphics with DirectX 8.1 hardware support and support
for multiple monitors. On the other hand, the companion IXP 300 South Bridge supports
Serial ATA and USB 2.0 as well as six-channel audio. The Radeon 9x00 IGP family in-
cludes the 9100 IGP, 9100 Pro IGP, and 9000 Pro IGP.
ATI's line of Pentium 4/Core2-compatible chipsets includes the RC410 (integrates
Radeon X300 3D graphics) and the RS400 (integrates Radeon X300 3D graphics and in-
cludes support for PCI Express x16 video). Both were sold under the Radeon Xpress 200
brand name. Although ATI has made South Bridge chips in the past, its Radeon Xpress
200 North Bridge chips can be paired with either ATI's own IXP 450 or ULi's M157x
South Bridge chips. ATI's South Bridge chips include the IXP 150, 200, 250, 300, 400,
and 450.

VIA Chipsets
VIA Technologies produced a number of chipsets for Pentium 4 processors in its P4X,
P4M, PT8 and PM8 series, as well as South Bridge chips (VT series). The PT8 and PM
series also supported Intel's Core 2 processors. Although VIA Technologies still lists a
wide range of chipsets on its website ( www.via.com.tw ) , the website states: “*Note: VIA
no longer sells some or all of these chipsets.”

NVIDIA Chipsets for Intel Processors
Although NVIDIA is not licensed to produce chipsets for the Intel i-series Core pro-
cessors, it continues to offer a wide variety of chipsets for Intel processors from the Pen-
tium 4 through the Core 2 Extreme series. Current offerings include the nForce 600 and
nForce 700i series, and the GeForce 7 and GeForce 9000 series with integrated video.
