This is what pattern dictated the Pentium Pro, Pentium II, and Pentium III should have been called. Intel didn't want to sell a product and have people think it was some sort of sex toy, so they added shit to their existing Pentium brand name.

So, all you folks reading there at home, your processor is not a Pentium III, it is in fact a Sextium.

It doesn't matter though, because the x86 technology stopped really improving at the Pentium anyway. All Intel and AMD really do these days is try to figure out how to emulate a 486 faster.
