- The brochure can be obtained by calling Intel Literature, 1-800-395-7009 ext
- 12, Monday through Friday 7am-5PM central time. Ask for information on the
- iCOMP index; the literature numbers are C5B32 and 76B4.

- From the brochures distributed in the iCOMP index press kit:
- (The brochure is 26 pages long and discusses how the iCOMP index came about,
- it's objectives and its technological foundations)
-
- "[The icomp index] is not a system benchmark, but an index of relative
- processor performance intended to help non-technical end users decide which
- Intel microprocessor best meets their desktop computing needs."
-
- "...[iCOMP index] is intended to suppliment, not replace benchmarks. ...it is a
- tool for making comparisons between different Intel processors. This does not
- mean that all systems with [the same processor] perform the same--differences
- in system design and configuration will effect performance considerably. ...
- However, given comparable configuration and design, the one with the higher
- iCOMP rating will have more power..."
-
- "The iCOMP index is a weighted average of several measures of processor
- performance. "
-
- The area of performance considered are: 16-bit integer, 16-bit floating point,
- 16-bit graphics, 16-bit video, 32-bit integer, 32-bit floating point, 32-bit
- graphics and 32-bit video. The benchmarks currently used to measure these
- include: SPEC CINT92, SPEC CFP92, Whetstone and Ziff Davis 7.0.
-
- "...as benchmarks become available and the typical application mix changes,
- the iCOMP index weightings will [be adjusted]."
