'''Celeron''' is a series of [[IA-32]] and [[x86-64]] computer [[microprocessor|microprocessors]] targeted at low-cost [[Personal computer|personal computers]], manufactured by [[Intel]] from 1998 until 2023.

The first Celeron-branded CPU was introduced on April 15, 1998, and was based on the [[Pentium II]]. Celeron-branded processors released from 2009 to 2023 are compatible with [[IA-32]] software. They typically offer less performance per clock speed compared to flagship Intel CPU lines, such as the [[Pentium]] or [[Intel Core|Core]] brands. They often have less [[CPU cache|cache]] or intentionally disabled advanced features, with variable impact on performance. While some Celeron designs have achieved strong performance for their segment, the majority of the Celeron line has exhibited noticeably degraded performance.<ref name="Schmid">{{cite news |last=Schmid |first=Patrick |title=The New Generation Is Here: Celeron 2.0&nbsp;GHz, with 0.13&nbsp;µm |url=http://www.tomshardware.com/reviews/generation,534.html |publisher=[[Tom's Hardware Guide]] |date=October 16, 2002 |access-date=July 30, 2007}}</ref> This has been the primary [[Market segmentation|justification for the higher cost]] of other Intel CPU brands versus the Celeron range.<ref> {{ cite-web | title=---anandtech.com/show/568/2 from ---forums.tomshardware.com/threads/celerons-rebadged-pentiums.302020/ <!--

In September 2022, Intel announced that the Celeron brand, along with Pentium, were to be replaced with the new "Intel Processor" branding for low-end processors in laptops from 2023 onwards.<ref name="Warren 2022"/> This applied to desktops using Celeron processors as well, and was discontinued around the same time laptops stopped using Celeron processors in favor of "Intel Processor" processors in 2023.
Then, Intel released the N100 CPU, an evolution of the mobile Celeron, in 2023. The Celeron had two cores, but the N100 has four cores. The maximum operating clock is 3.40GHz, the TDP is 6W. The maximum RAM capacity is 16GB.<ref>https://www.intel.co.jp/content/www/jp/ja/products/sku/231803/intel-processor-n100-6m-cache-up-to-3-40-ghz/specifications.html</ref>
