Datasheet
The term “Pentium
III
Xeon processor” refers to the cartridge package which interfaces to a host
system board through a SC330 Connector. Pentium
III
Xeon processors include a processor core, a
level 2 cache, system bus termination and various system management features. The Pentium
III
Xeon processor includes a thermal plate for cooling solution attachment and a protective cover.
1.1.1
S.E.C. Cartridge Terminology
The following terms are used often in this document and are explained here for clarification:
•
Cover — The processor casing on the opposite side of the thermal plate.
•
Pentium
®
III
Xeon™ processor — The 100 MHz SC330 product including internal
components, substrate, thermal plate and cover.
•
L1 cache — Integrated static RAM used to maintain recently used information. Due to code
locality, maintaining recently used information can significantly improve system performance
in many applications. The L1 cache is integrated directly on the processor core.
