iCOMP for Intel Comparative Microprocessor Performance was an index published by Intel used to measure the relative performance of its microprocessor

Microprocessor

A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

s.

There were three revisions of the iCOMP index. Version 1.0 was benchmarked against the 486SX 25, while version 2.0 was benchmarked against the Pentium 120.
