Pentium III Katmai is a Sample, which is still labeled as a Pentium II built on a 0.25 µm process. The initial Katmai was very much similar to the Pentium II. The only differences being the introduction of SSE and an improved L1 cache controller. It was initially released at speeds of 450 and 500 MHz. Later on it was released at 550 MHz and 600 MHz. It used the same slot that was designed for Pentium II.
