Pentium II/233 To 450: May 1997 To August 1998

The Pentium II Slot 1 with 9 million transistors was supplied with two different cores: Klamath and Deschutes. The differences were in how they were packaged and the FSB speed, 66 MHz or 100 MHz. The fastest CPU of the time was becoming something of a room heater: the 250 nm design resulted in a maximum thermal dissipation for the Klamath of 43 W.
