Encyclopedic overview
The Pentium Pro is the first sixth-generation x86-based microprocessor developed and manufactured by Intel and introduced on November 1, 1995. It was the first x86-based Intel processor to implement the P6 microarchitecture (sometimes termed i686), and was designed to be the successor to the P5 of the original Pentium in the workstation and server CPU lineup.
While the Pentium and Pentium MMX had 3.1 and 4.5 million transistors, respectively, the Pentium Pro contained 5.5 million transistors. It was capable of both dual- and quad-processor configurations and only came in one form factor, the relatively large rectangular Socket 8.
