Pentium is a discontinued series of x86 architecture-compatible microprocessors produced by Intel. The original Pentium was first released on March 22, 1993. The name "Pentium" is originally derived from the Greek word pente (πεντε), meaning "five", a reference to the prior numeric naming convention of Intel's 80x86 processors (8086–80486), with the Latin ending -ium since the processor would otherwise have been named 80586 using that convention.
