Mobile Pentium II was a family of high performance P6-based microprocessors introduced by Intel in 1998.

Overview

Mobile Pentium II were originally introduced in April of 1998. Like their desktop counterparts, they were also packaged in a Mini-Cartridge instead of in a socket setup. The package allowed Intel to separate the cache from the die while still keeping everything closely tied together with respect to the back-side bus. The separate (slower) cache die also meant the processor was cheaper to manufacture.

A second wave of chip were released in early 99 which had lower TDP, higher clock, and the cache was once again moved on-die.
