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.

March 1999 to March 2000
The "enhanced Pentium II" for slot 1 was available
at speeds of between 450 MHz and 1000 MHz. The PIII on the Katmai
core was fitted with 512 KB external L2 cache, whereas the
Coppermine was fitted with 256 KB L2 cache.
