Intel · Pentium III Xeon · 2000 · Slot 2
The Intel Pentium III Xeon 866 2.8V is a server processor with 1 core, released in 2000. It is part of the Pentium III Xeon lineup, using the Pentium III Xeon platform, and fits the Slot 2 socket. Internally, it is built on the "Cascades" architecture. It operates at a fixed 0.866 GHz. Intel manufactures the "Cascades" silicon on a 180nm process node. This processor supports SDRAM memory across 1 channels, up to 4GB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations. With a TDP of 25W, the Pentium III Xeon 866 2.8V is an efficient chip suitable for modest cooling solutions. The cache hierarchy consists of no dedicated of L1 and no dedicated of L2 cache. There is no L3 cache on this processor.
Pentium III Xeon 'Cascades' — die-shrunk to 180nm, extending the Slot 2 server platform into 2000-2001 before the transition to Socket 603/604.
