This document describes both the Intel 450KX and 450GX PCIsets. Unshaded areas apply to both the
PCIsets. Shaded areas, like this one, describe the 450GX operations that differ from the 450KX.
The Intel 450KX/GX PCIsets provide a high-performance system solution for Pentium Pro processor-based
PCI systems by combining high integration, high performance technology with a scalable architecture that is
capable of high throughput for up to four Pentium Pro processors. Scalability provides a wide range of system
solutions from cost-effective uniprocessor systems to high-end multiprocessor systems without sacrificing
performance. For systems requiring extensive I/O (e.g., file servers), a second PB can be easily added
providing two high-performance PCI bus structures. The flexibility of the memory controller permits easy
expansion from a simple non-interleaved organization to a 2-way or 4-way interleaved organization to increase
performance. Extended error checking and logging, ECC, and the ability to build in redundancy (e.g, multiple
processors and dual PCI bridges) provides a comprehensive solution for systems requiring high reliability.
The PCIset may contain design defects or errors known as errata. Current characterized errata are available
upon request.
