The original Pentium branded CPUs were expected to be named 586 or i586, to follow the naming convention of previous generations (286, i386, i486). However, as the company wanted to prevent their competitors from branding their processors with similar names (as AMD had done with their Am486), Intel attempted to file a trademark on the name in the United States, only to be denied because a series of numbers was not considered distinct.[3]
Following Intel's previous series of 8086, 80186, 80286, 80386, and 80486 microprocessors, the company's first P5-based microprocessor was released as the original Intel Pentium on March 22, 1993. Marketing firm Lexicon Branding was hired to coin a name for the new processor. The suffix -ium was chosen as it could connote a fundamental ingredient of a computer, like a chemical element,[4] while the prefix pent- could refer to the fifth generation of x86.

Po spominu so bili 268, 386, 486, 468DX2, potem je bil pa Pentium (oz. Pentium 1) oz. pogovorno "586"
486DX2 ni bil svoj model, pač pa verzija procesorja, kjer je jedro teklo z dvojno hitrostjo kot vodilo do matične plošče (to je še zdaj prisotni multiplier). Obstajali so tudi DX4 procesorji, kjer je jedro teklo z trikratno hitrostjo vodila.
