VIA PT880 Chipset: Intuitive Technologies Powering the Intel?
Pentium? 4 Platform
The PT880 represents a revolutionary new North Bridge architecture design from VIA
and includes a host of new intuitive memory technologies, providing exceptional
system performance and a rich digital media experience. Featuring the revolutionary
DualStream64? memory controller, a new approach to dual channel memory
technologies with support for up to 8GB of DDR400 SDRAM, the VIA PT880 integrates
support for 800MHz FSB, Hyper-Threading, AGP 8X and utilizes an asynchronous bus
design to maximize system optimizations and flexibility. Ultra V-Link provides a high
throughput 1066MB/s interconnect between the North and South Bridge.
In combination with the acclaimed VIA VT8237 South Bridge, the VIA PT880 offers the
most complete range of storage, multimedia and connectivity features for the Intel
Pentium 4 processor. In addition to enabling native support for two Serial ATA Hard
Drives and up to four IDE devices, it provides optimal data transfer rates and data
integrity through V-RAID, a revolutionary integrated RAID controller with support for
multiple RAID configurations. The VT8237 also features the VIA Vinyl Multichannel
Audio Suite for superlative 6-channel and 8-channel immersion audio support, while
VIA’s Advanced Connectivity Suite offers a host of high-bandwidth connectivity options,
including support for the VIA Velocity Gigabit Ethernet companion controller,
integrated 10/100Mbps Fast Ethernet and up to eight high-speed USB 2.0 ports.
The VIA PT880 is part of VIA’s unique Modular Architecture Platform (V-MAP) that
reduces design times and shortens time-to-market for motherboard partners through
pin-compatibility across VIA core logic solutions, and allows motherboard partners to
cover multiple market segments with a single design.

DualStream64 Memory Controller
Harnessing revolutionary new intuitive technologies,
the VIA DualStream64 memory controller enables
lightning fast access to system memory and optimum
system performance through an enhanced data
prefetch protocol.
Further performance enhancements include improved memory branch prediction,
utilizing a larger on-chip branch table, and tighter read/write turnaround for
significantly improved clock timings. With an asynchronous bus design, the PT880
allows maximum system flexibility and optimization options, as demanded by today’s
power users.
Figure 2 below shows the SiSoft Sandra benchmark for testing the memory bandwidth
performance of competing platforms; the VIA PT880 clearly enjoys a significant
memory bandwidth boost from DualStream64’s intuitive technologies, through the
expanded array of prefetch buffers, superior data prediction technology and lower
latency clock cycles.
