Editor's take: Intel’s Celeron line of processors debuted in the late 90s as a more affordable alternative to its pricier Pentium II line and to challenge rivals like AMD and Cyrix in the entry-level segment. Early models also developed a reputation among enthusiasts as being excellent overclockers and some are still being tinkered with to this day.
