Pentagram Pro
= P =
peon
Pentium n.
The name given to Intel's P5 chip, the
successor to the 80486. The name was chosen because of difficulties
Intel had in trademarking a number. It suggests the number five
(implying 586) while (according to Intel) conveying a meaning of
strength "like titanium". Among hackers, the plural is
frequently `pentia'. See also Pentagram Pro.
Intel did not stick to this convention when naming its P6 processor
the Pentium Pro; many believe this is due to difficulties in
selling a chip with "hex" or "sex" in its name. Successor
chips have been called `Pentium II', `Pentium III', and
`Pentium IV'.
