Pentium III Microprocessor

The Pentium III microprocessor, code named Katmai, was the next member of the P6 family to follow the Pentium II processor in the famous Intel IA-32 processor line. Released in early 1999, design engineers were able to squeeze 9.5 million transistors onto a relatively small silicon die by employing 0.25-micron, 4-layer chip fabrication technology.
