The P6 Processor Family

All Intel® IA32 processors in the Pentium® Pro, Pentium® II and Pentium® III product lines (including Celerons and Xeons) are referred to as P6 family processors because they were all based on variants of the P6 processor core. The three core variants were code named (in chronological order) as follows:

• The Klamath core.

• The Deschutes core.

• The Katmai core.

The next three sections provide an overview of these three cores and the products that were based on each of them.
