Intel® Pentium® III Processor

The Pentium® III processor is ideal for high performance applied computing. It supports highend communications, transaction terminal, and industrial automation applications. While incorporating new features and improvements, the Pentium III processor remains software compatible with previous members of the Intel microprocessor family.

The Pentium III processor is validated with multiple chipsets for maximum flexibility and scalability. Combined with the Intel 840 chipset, the Pentium III processor provides high performance and bandwidth including dual processing and a second PCI bus. The 815, 815E, 810 and 440BX chipsets provide a scalable platform supporting a wide selection of Celeron® and Pentium III processors ranging from 66 to 133 MHz processor side bus speeds. The 440BX AGPset supports ECC for the highest data integrity and ISA for legacy I/O. The Intel 815, 815E and 810 chipsets utilize Intel Graphics Technology, an integrated graphics platform which provides more stability, higher quality graphics and a reduced OEM bill of materials cost.
