The first Pentium III variant was the Katmai (Intel product code 80525). It was a further development of the Deschutes Pentium II. The Pentium III saw an increase of 2 million transistors over the Pentium II.
The first Pentium III core, Katmai, was not much different from its predecessor, Pentium II Deschutes core. Like the Deschutes-based Pentium II processors, the Katmai-based Pentium III CPUs had 512 KB back-side L2 cache running at half of the core frequency.
The Pentium III from Intel is a sixth-generation CPU targeted at the consumer market. Desktop processors. "Katmai" (250 nm) 9.5 million transistors. All models support: MMX, SSE. The 'B' suffix denotes a 133 MHz FSB. The '80525PYxxx512' number denotes an OEM CPU while the 'BX80525xxxx512' or 'BX80525xxxx512E' number denotes a boxed CPU.
