# Pentium II

The Pentium II is an x86 architecture microprocessor by Intel, introduced in February 1997. It was based on a modifed version of the P6 core first used for the Pentium Pro, but with improved 16-bit performance and the addition of the MMX instructions which had already been introduced on the Pentium MMX.

A low-end version of the Pentium II - essentially a Pentium II with less level 2 cache - was marketed under the name "Celeron". The Pentium II Xeon[?] was a high-end version intended for use on servers.

The Pentium II was eventually superseded by the Pentium III.
