From PC Magazine, December 8, 1992:
"The current iCOMP index is made up of four weighted components: 16-bit
integer (67 percent), 16-bit floating point (3 percent), 32-bit integer
(25 percent), and 32-bit floating point (5 percent).  Those weightings
reflect Intel's best guess about the importance of each component in
applications over the next three to five years (the average system
lifetime).  But Intel expects to update the formula as new CPU
capabilities emerge (graphics and video are two likely candidates), and
as applications change (as more of them take advantage of 32-bit
technology, for example)."
