VIA today announced the VIA PT Series of chipsets for the Intel® Pentium® 4
platform, providing a smooth transition for motherboard manufacturers and their
customers to new technologies such as PCI Express and DDR2 memory. The new
chipsets, which include the VIA PT880 Pro and PT894 chipsets, targeted at the
performance mainstream market, and the PT894 Pro, a solution optimized for the
workstation and power user segments, all support the latest Intel® Pentium® 4
and Celeron™ processors up to 1066MHz FSB.

For the first time, VIA provides the considerable benefit of being able to
use PCI Express and AGP Graphics cards on the same motherboard, thanks to the
unique VIA Universal Graphics Interface (UGI) featured in the VIA PT880 Pro
chipset. For users requiring powerful multitasking capabilities, enhanced
multi-display support is provided through the advanced VIA DualGFX Express
technology, which enables connection up to 4 monitors through dual graphics
cards. VIA DualGFX Express support is offered by the VIA PT894 Pro chipset,
connecting to dual PCI Express graphics cards, and the VIA PT880 Pro chipset,
connecting to a PCI Express and AGP graphics card simultaneously.

Express support is offered by the VIA PT894 Pro chipset, connecting to dual PCI
Express graphics cards, and the VIA PT880 Pro chipset, connecting to a PCI
Express and AGP graphics card simultaneously.

Furthermore, all PT Series chipsets offer the option of using either DDR or DDR2
system memory on the same motherboard through VIA StepUp Technology. With
support for DDR memory up to 400MHz, and DDR2 memory at up to 667MHz, VIA StepUp
Technology provides end-users and system integrators the flexibility to use
whatever memory standard suits their requirements.

"Based on feedback from our customers, there is strong demand for a chipset
architecture that provides the bridge between new technologies such as PCI
Express, DDR2 and LGA775 processors, and established technologies like DDR and
AGP graphics,” commented Richard Brown, Associate Vice President of Marketing,
VIA Technologies Inc. “While other PCI Express chipset solutions are not able to
offer this, largely ignoring the needs of many mainstream users, the new VIA PT
Series chipsets offer a uniquely flexible platform that ensures smooth
transition and, ultimately, faster adoption of PCI Express and DDR2
technologies.”

PT Series chipset North Bridges can be combined with either the acclaimed VIA
VT8237 South Bridge, or the forthcoming VIA VT8251 South Bridge. As the world’s
most advanced I/O and storage technology interface for PCs, the VT8251 South
Bridge features a host of cutting edge features including SATA II, RAID 5 and
High Definition Audio™.

VIA’s unique architecture also allows motherboard manufacturers to utilize more
affordable 4-layer PCBs, as opposed to more expensive 6-layer PCBs, without
compromising on system performance or stability. By contrast, market research
shows that the significant majority of current and forthcoming motherboards
based on competitors’ chipsets require 6-layer PCBs in order to work at a stable
level, thereby significantly increasing the platform cost.

About the VIA PT880 Pro Chipset
The VIA PT880 Pro chipset provides the perfect stepping stone solution during
transition to PCI Express and DDR2 for system integrators and enthusiasts. The
VIA PT880 Pro chipset features the unique VIA Universal Graphics Interface (UGI)
to allow support for both PCI Express and AGP graphics on the same motherboard,
allowing system integrators and users the ability to upgrade their platform and
continue using AGP graphics, or migrate to PCI Express graphics at a time that
suits them.

The PT880 Pro chipset is world’s only chipset to feature a true AGP graphics
controller in combination with PCI Express graphics, ensuring all graphics cards
can reach their full performance potential. Furthermore, users can also benefit
form VIA DualGFX technology by using both AGP and PCI Express graphics cards at
the same time, providing enhanced multi-display support through the ability to
connect up to 4 displays. Further information on the VIA PT880 Pro chipset may

About the VIA PT894 Chipset
Targeted at the Performance Mainstream Market, the VIA PT894 chipset features in
a new generation of motherboards offering a cost effective alternative to highly
priced i915 chipset based motherboards supposedly targeted at the mainstream. By
enabling advanced PCI Express technology, as well as support for 1066MHz
processors and high-speed DDR2 memory, on motherboards priced within the
accepted price range for the mainstream market, the VIA PT894 chipset will help
speed up the adoption of PCI Express graphics cards and peripherals, as well as
DDR2 memory.

Furthermore, by supporting two PCI Express x1 connections directly to the
chipset’s North Bridge, the latest PCI Express peripheral devices such as HDTV
Tuner Cards, as well as Gigabit Ethernet, SCSI and RAID controllers, are
guaranteed high-speed connections with reduced latency and bottlenecks. Further

About the VIA PT894 Pro Chipset
By harnessing VIA DualGFX Express technology, motherboards based on the VIA
PT894 Pro chipset can support dual PCI Express graphics cards. VIA Dual GFX
Express enables enhanced multitasking through support for up to four monitors,
without compromising system performance. In the past to connect to any more than
two monitors required use of an AGP graphics card and a standard PCI Graphics
card, or upgrading to a very expensive Pro workstation graphics card.

VIA DualGFX Express, the only dual graphics card interface to offer a total of
twenty PCI Express lanes of graphics bandwidth, makes multi-display platforms
easier and more affordable for wider range of users beyond just workstation
environments. Other areas that can benefit from VIA DualGFX Express and
multi-display platforms include digital video and audio editing, gaming and
financial market applications. Further information on the VIA PT894 Pro chispet
