Pentium II Processors
Intel revealed the Pentium II in May 1997. Prior to its official unveiling, the Pentium II
processor was popularly referred to by its code name, Klamath, and was surrounded by
much speculation throughout the industry. The Pentium II is essentially the same sixth-
generation processor as the Pentium Pro, with MMX technology added (which included
double the L1 cache and 57 new MMX instructions); however, there are a few twists to
the design. The Pentium II processor die is shown in
