Intel's high-end x86-based CPU chips, pronounced "zee
-ahn." Xeon chips are faster and more advanced than the mainstream Intel lines (Pentium, Core, etc.). Designed for servers and high-end workstations, Xeons include error-checking memory (see ECC
) and system management features (see SMBus
) not found in the regular chips. They have from two to 18 cores, the fastest system buses and largest memory capacities with some chips addressing a terabyte of RAM.
Xeon Model Designations
Introduced in 1998, Xeons have used various model names and numbers: Xeon Pentium II, Xeon Pentium III, Xeon DP (dual processor), Xeon MP (multiprocessor), Xeon 3000, 5000, 6000, 7000, Xeon E3, E5, E7 and Xeon Bronze, Silver and Gold. See x86
