Intel® 440BX AGPset product overview
 
* Intel® 440BX AGPsetThe Intel® 440BX AGPset is the first chip set to deliver 100-MHz system level bandwidth to unleash the full performance of the Intel® Pentium® II processors at 350-MHz or 400-MHz. In addition, the Mobile Intel® 440BX chip set is the first chip set to bring Pentium II processor performance to mobile systems.

The Intel 440BX AGPset improves system performance by increasing the bandwidth of the system bus from 66MHz to 100MHz.

Highest System Performance through Technology Innovation
The chip set features Intel's Quad Port Acceleration (QPA) to improve bandwidth between the Pentium II processor, the Accelerated Graphics Port, 100-MHz SDRAM and the PCI bus. QPA combines enhanced bus arbitration, deeper buffers, open-page memory architecture and ECC memory control to improve system performance.

Ultimate Design Flexibility
The Intel 440BX AGPset provides developers with maximum design flexibility by delivering one chip set for both 66MHz and 100MHz system designs. Now, one basic motherboard design supports all Pentium II processor speeds from 233MHz to 400MHz. This flexibility can save engineering resources while maximizing use of investments in BIOS, software development and compatibility testing.

Closing the Gap Between the Desktop and Mobile
The Intel 440BX chip set architecture supports Mobile Intel Pentium II processor performance—bringing desktop-like performance to mobile PCs. It also enables mobile systems to benefit from advanced power management and Wired for Management capabilities, allowing mobile platforms to function much like desktop systems when connected to a network.

Intel® 440BX AGPset Highlights:
  • Optimizes Pentium II processor 350/400-MHz performance by enabling 100-MHz SDRAM and memory.

  • Supports both 100-MHz or 66-MHz system and memory bus designs.

  • Quad Port Acceleration improves system performance.

  • Enables "best-of-class" 3D and multimedia and gaming platforms with the Intel740™ graphics accelerator-based graphics card.

  • ACPI-compliant power manageability.

  • Supports Wired for Management capabilities in desktop and mobile platforms.

  • The first chip set to support the Mobile Intel Pentium II processor.

  • Quality and reliability of Intel's pre-silicon simulations and post-silicon validation processes.

  • World-class manufacturing and support capabilities.
