==== Northwood-128 ====
These socket 478 Celerons are based on the ''[[Pentium 4#Northwood|Northwood]]'' Pentium 4 core, and also have 128&nbsp;KB of L2&nbsp;cache. The only difference between the ''Northwood-128''-based and the ''Willamette-128''-based Celeron is the fact that it was built on the new 130&nbsp;nm process which shrank the die size, increased the transistor count, and lowered the core voltage from 1.7&nbsp;V on the ''Willamette-128'' to 1.52&nbsp;V for the ''Northwood-128''. Despite these differences, they are functionally the same as the Willamette-128 Celeron, and perform largely the same clock-for-clock. The ''Northwood-128'' family of processors were initially released as a 2&nbsp;GHz core (a 1.9&nbsp;GHz model was announced earlier, but never launched<ref>{{cite news|last=Sigvartsen|first=Ana|title=Intel plans faster 0.13-micron Celeron|url=http://www.infosatellite.com/news/2002/06/a170602celeron.html|publisher=Infosatellite.com|date=June 17, 2002|access-date=July 30, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071012160303/http://infosatellite.com/news/2002/06/a170602celeron.html|archive-date=October 12, 2007|df=dmy-all}}</ref>) on September 18, 2002.<ref>{{cite news|last=Sigvartsen|first=Ana|title=Intel launches new Celeron, updates prices|url=http://www.infosatellite.com/news/2002/09/a190902celeron.html|publisher=Infosatellite.com|date=September 19, 2002|access-date=July 30, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071006095201/http://www.infosatellite.com/news/2002/09/a190902celeron.html|archive-date=October 6, 2007|df=dmy-all}}</ref> Since that time Intel has released a total of 10 different clock speeds ranging from 1.8&nbsp;GHz to 2.8&nbsp;GHz, before being surpassed by the Celeron D. Although the ''Northwood''-based Celerons suffer considerably from their small L2&nbsp;cache, some clock rates have been favored in the enthusiast market because, like the old 300A, they can run well above their specified clock rate.<ref name="Schmid" />

In Intel's "Family/Model/Stepping" scheme, Northwood Celerons and Pentium 4s are family 15, model 2, and their Intel product code is 80532.
