The Pentium® II/Xeon/Celeron Roadmap

The following is a list of the major milestones in the Pentium® II's evolution:

• The original Pentium® II was based on the .28μm Klamath core and had a FSB speed of 66MHz.

• Deschutes was based on the 0.25 μm process and had a 100MHz FSB (as did all subsequent Pentium® II processors).

• Tonga was the mobile version of the Pentium® II and was based on the 0.25μm process.

• Covington was the first Celeron processor. Intel® found themselves in the position of losing market share to AMD because it did not have a small form factor, low-cost processor that would fit well into small footprint machines. While engineering worked on the development of such a processor, Covington was introduced as the short-term solution. Basically, ...
