“Many users will be upgrading to
new Socket-A platforms and
there's none faster than the
KT333. When it comes to the
Athlon XP, it's not about choosing
a chipset; it's about picking a
motherboard.”

new ATI 9700
The new AGP 3.0 specification is implemented in the KT400
Features:
• Doubles frequency to 533MHz
• Maximum Data Transfer of 2.1GB/sec
• Backwards compatible with AGP 4X devices
Benefits
• Leverages fast system memory like DDR333 and more powerful
CPUs
• Enables larger texture maps to be stored reducing the pressure on
local frame buffer memory
• Provides headroom for future advances in graphics technology and
offers more scope to hardware and software developers to push
the boundaries of realism & quality8X V-Link – Eliminating the PCI
bottleneck
8X V-Link transfers up to 533MB/s of data
2X - Intel Hub Architecture
4X - Conventional PCI bus
• CLK rate 66MHz
• Quad data pump per CLK, 266MB/S each
direction
• Concurrent data up/down streams
Leveraging the speed and efficiency of USB 2.0
and ATA/133 integrated in the South Bridge to
feed the powerful processor and memory
system with the data they need for optimum
performance.USB 2.0 - 40X Faster
Following the widespread success of USB 1.1, VIA now sees the
drive to new industry standard USB 2.0 as a natural evolution,
meeting the greater bandwidth demands of today’s PC peripherals
and applications, from higher resolution video to fast storage unit
access.
• 480 Mbps data capacity
• Backwards compatible with USB 1.1
• Ideal for today’s bandwidth-hungry peripherals such
as video cameras and next generation scanners and
printers
• Enhances the performance of demanding applications
such as interactive gaming and digital photography.VIA Interactive Support
In 2001 VIA launched an interactive dedicated
support website,
• Latest Driver Downloads
• Beta Drivers for Enthusiasts
• Support Forums
• Content designed to help end users enhance
their experiences
