The Introduction of the Celeron

As described earlier (see “The Pentium® II/Xeon/Celeron Roadmap” on page 660), the Celeron processor was initially introduced as a variant of the Pentium® processor. It had the following characteristics:

  • The FSB arbitration scheme only supports one processor.

  • The FSB operational frequency was 66MHz (the same as the high-end versions of the Pentium® Pro). It was deliberately designed to operate at a lower frequency than the Pentium® II to differentiate it from the higher priced Pentium® II.

  • The first version (code-name Covington) eliminated the L2 Cache, resulting in worse performance than a high-end Pentium® processor. It had a revised cartridge format.

  • Celeron Mendocino added an on-die 128KB L2 Cache, a full-speed ...
