These Celeron processors, released initially at 1.2&nbsp;GHz on October 2, 2001,<ref>{{cite news|last=Sigvartsen |first=Ana |title=Intel's Celeron reaches 1.2&nbsp;GHz |url=http://www.infosatellite.com/news/2001/10/j031001celeron_12ghz.html |publisher=Infosatellite.com |date=October 2, 2001 |access-date=July 31, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20071012160212/http://infosatellite.com/news/2001/10/j031001celeron_12ghz.html |archive-date=October 12, 2007 }}</ref> were based on the Pentium III ''' '[[Pentium III#Tualatin|Tualatin]]'''' core and made with a 0.13 micrometer process for the [[FCPGA|FCPGA 2]] Socket 370. They were nicknamed "Tualeron" by some enthusiasts — a portmanteau of the words [[Pentium III#Tualatin|Tualatin]] and Celeron. Some software and users refer to the chips as ''Celeron-S'', referring to the chip's lineage with the Pentium III-S, but this is not an official designation. Intel later released 1&nbsp;GHz and 1.1&nbsp;GHz parts (which were given the extension ''A'' to their name to differentiate them from the Coppermine-128 of the same clock rate they replaced).<ref>{{cite news|last=Sigvartsen|first=Ana|title=Intel's Celeron gets major power boost|url=http://www.infosatellite.com/news/2001/12/h071201celeron_tualatin.html|publisher=Infosatellite.com|date=December 7, 2001|access-date=July 31, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071012160217/http://infosatellite.com/news/2001/12/h071201celeron_tualatin.html|archive-date=October 12, 2007|df=dmy-all}}</ref> A 1.3&nbsp;GHz chip, launched January 4, 2002,<ref>{{cite news|last=Sigvartsen|first=Ana|title=Intel launches Celeron 1.3&nbsp;GHz|url=http://www.infosatellite.com/news/2002/01/h040102intel_celeron_3ghz.html|publisher=Infosatellite.com|date=January 4, 2002|access-date=July 31, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071012160232/http://infosatellite.com/news/2002/01/h040102intel_celeron_3ghz.html|archive-date=October 12, 2007|df=dmy-all}}</ref> and finally a 1.4&nbsp;GHz chip, launched May 15, 2002 (the same day as the 1.7&nbsp;GHz Willamette-based Celeron launch),<ref>{{cite news|last=Sigvartsen|first=Ana|title=Intel launches Celeron with new core|url=http://www.infosatellite.com/news/2002/05/a160502celerons.html|publisher=Infosatellite.com|date=May 16, 2002|access-date=July 31, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071012160237/http://infosatellite.com/news/2002/05/a160502celerons.html|archive-date=October 12, 2007|df=dmy-all}}</ref> marked the end of the Tualatin-256 line.

The most significant differences compared to the Pentium III Tualatin are a lower 100&nbsp;MHz bus and fixed 256&nbsp;KB of L2 cache (whereas the Pentium III was offered with either 256&nbsp;KB or 512&nbsp;KB L2 cache); cache associativity stayed at 8-way,<ref>download.intel.com/support/processors/celeron/sb/29859604.pdf</ref> although the newly introduced data prefetching appears to have been disabled.<ref>{{cite web|url=https://www.realworldtech.com/data-prefetching/|title=Data Prefetch Logic - What is it Worth?|website=www.realworldtech.com|access-date=April 4, 2018}}</ref> Furthermore, the Tualatin-256's L2 cache has a higher latency which boosted manufacturing yields for this budget CPU.{{Citation needed|date=December 2017}} On the other hand, this improved stability when overclocking and most of them had no problem working at 133&nbsp;MHz FSB for a substantial performance increase.

Despite offering much improved performance over the Coppermine Celeron it superseded, the Tualatin Celeron still suffered stiff competition from AMD's [[Duron]] budget processor.<ref>{{cite news|first=Frank| last=Völkel |author2=Töpelt, Bert|title=Intel vs. AMD: Celeron 1300 vs. Duron 1200|url=http://www.tomshardware.com/2002/01/03/intel_vs/|publisher=[[Tom's Hardware Guide]] | date=January 3, 2002|access-date=July 31, 2007}}</ref> Intel later responded by releasing the NetBurst Willamette Celeron, and for some time Tualatin Celerons were manufactured and sold in parallel with the Pentium 4-based Celerons that replaced them.

In Intel's "Family/Model/Stepping" scheme, Tualatin Celerons and Pentium IIIs are family 6, model 11 and their Intel product code is 80530.
