Product Description
Together with its Pentium III processor for mainstream PC's, Intel has released the Pentium III Xeon processor for servers and workstations. This new Xeon inroduces the same improvements over the older version as the Pentium III brings to the older Pentium II. KNI, the Katmai New Instruction set, is incorporated into the PIII Xeon, making this processor even more ideal for high-end graphics workstations. The new Xeon also uses the Pentium III's memory streaming architecture, and has an embedded processor serial number for improved management over networks. Additionally, like previous Xeons, the Pentium III Xeon supports the MMX instruction set. Improvements over the Pentium III processor include support for SMP (symmetric multi-processing) in up to eight-way configurations, and L2 cache memory running at the full processor clock speed (as opposed to one-half clock speed in the PIII). The Xeon is the first Intel processor to use a Slot 2 motherboard connector. Slot 2 is the form factor that will be used for Intel's high-end server and workstation processors, distinguishing them from mainstream PC processor families, such as the Pentium II and Celeron, which will continue to use Slot 1. This is analogous to the Socket 8 connector used by the Pentium Pro, which differentiated it from Intel's mainstream Socket 7 processor, the classic Pentium. The Slot 2 form factor used by Xeon is incompatible with Slot 1 motherboards, and requires a motherboard with a Slot 2 connector and a chipset that supports the Xeon processor.
