Product Overview
The Pentium® Pro processor family is Intel's next generation of performance for high-end desktops, workstations and servers. The family consists of processors at 150 Mhz and higher and is easily scalable to up to four microprocessors in a multiprocessor system. The Pentium Pro processor delivers more performance than previous generation processors through an innovation called Dynamic Execution. This is the next step beyond the superscalar architecture implemented in the Pentium processor. This makes possible the advanced 3D visualization and interactive capabilities required by today's high-end commercial and technical applications and tomorrow's emerging applications. The Pentium Pro processor also includes advanced data integrity, reliability, and serviceability features for mission critical applications.

The Pentium Pro processor may contain design defects or errors known as errata. Current characterized errata are available upon request.
