VIA P4X333 Chipset

This product is available fully ROHS-compliant.

Fusing the unequalled bandwidth of DDR333 with the Intel® Pentium® 4 processor, the VIA Apollo P4X333 with 533MHz processor bus, AGP 8X, ATA-133, USB 2.0 and Double-Speed V-Link chip interconnect, is a new paradigm in total system performance

In addition, the VIA Apollo P4X333 supports the very latest technologies including AGP 8X deriving maximum performance from the most powerful graphics cards, and new Double-Speed V-link chip interconnect with 533MB/s of bandwidth between North and South Bridge. The new VT8235 South Bridge also features first to market innovations including USB 2.0 support for peripheral connectivity 40 times faster than USB 1.1, and ATA-133 support, the fastest IDE interface available, making total system performance a reality.

The VIA Apollo P4X333 is part of the V-MAP family of chipsets, which provides pin compatibility across the full range of VIA DDR products. V-MAP, or VIA Modular Architecture Platform, allows motherboard manufacturers, OEMs, and System Integrators to serve different market segments with a single, unified platform design. The VIA Apollo P4X333 (model number VT8754) is completely pin-compatible with the VIA Apollo P4X266A (VT8753A) to ensure rapid time to market and lower product development costs, ultimately delivering value to the end user.

Benefits of VIA P4X333

Ultra Powerful Performance
The VIA Apollo P4X333 features the world's fastest single channel memory controller, designed for exceptionally high performance. With a 400MHz/533MHz processor bus and supporting DDR200/266/333 memory, the VIA Apollo P4X333 provides lightning fast access to system memory and can reach a peak bandwidth of 2.7GB/sec, 25% greater than the P4X266A, enabling the full performance potential of the fastest Intel® Pentium® 4 processors to be harnessed.

Ultimate Connectivity
The VT8235 South Bridge with double speed V-link, USB 2.0 and ATA-133 provides the most advanced connectivity features to ensure the ultra fast processor and memory are not restricted by peripheral bottlenecks. USB 2.0 and ATA-133 high-speed transfer technologies are essential for today's bandwidth-hungry peripherals, and greatly enhance the performance of demanding applications including interactive gaming and digital photography.

VIA Modular Architecture Platform (V-MAP)
The VIA Modular Architecture Platform offers a balance of reliability and flexibility. Reliability comes from using proven, modular components and evolutionary design principles in enabling the VIA Apollo P4X333 to share the best characteristics of award winning previous generation products like the VIA Apollo P4X266A. Flexibility comes from the North Bridge design being pin compatible with the P4X266 and P4X266A, giving VIA customers cost and time to market advantages in developing next generation platforms.
