The Conroe-L Celeron is a single-core processor built on the [[Core (microarchitecture)|Core microarchitecture]] and is thus clocked much lower than the Cedar Mill Celerons, but still outperforms them. It is based on the 65&nbsp;nm [[Conroe (microprocessor)#Conroe-L|Conroe-L]] core,<ref>{{cite news| last=Huynh| first=Anh| title=Intel "Conroe-L" Details Unveiled| url=http://www.dailytech.com/article.aspx?newsid=4252| work=[[DailyTech]]| date=September 20, 2006| access-date=September 23, 2006| url-status=dead| archive-url=https://web.archive.org/web/20120306021304/http://www.dailytech.com/article.aspx?newsid=4252| archive-date=March 6, 2012| df=dmy-all}}</ref> and uses a 400-series model number sequence.<ref>{{cite news|url=http://www.vr-zone.com/?i=4657|title=Intel Adds Cheapest Celeron 420 In June|last=Visionary|date=February 13, 2007|work=VR-Zone|access-date=December 20, 2019|url-status=dead|archive-url=https://web.archive.org/web/20070303210711/http://www.vr-zone.com/?i=4657|archive-date=March 3, 2007}}</ref> The FSB was increased to 800&nbsp;MT/s from 533&nbsp;MT/s in this generation, and the TDP was decreased from 65&nbsp;W to 35&nbsp;W. As is traditional with Celerons, it does not have Intel [[X86 virtualization|VT-x]] instruction support or [[SpeedStep]] (although Enhanced Halt State is enabled, allowing the Celerons to lower the multiplier to 6× and decrease core voltage while idle). All Conroe-L models are single-core processors for the value segment of the market, much like the AMD K8-based [[Sempron]]. The product line was launched on June 5, 2007.<ref>{{cite news | url=http://www.heise.de/newsticker/meldung/90628 | title=Pentium Dual-Core E1000, Celeron 400, P35 und G33 starten offiziell | language=de | work=[[Heinz Heise|Heise News Ticker]] | date=June 5, 2007 | access-date=June 13, 2007}}</ref>

On October 21, 2007, Intel presented a new processor for its Intel Essential Series. The full name of the processor is Celeron 220 and is soldered on the D201GLY2 motherboard. With 1.2&nbsp;GHz and a 512&nbsp;KB L2&nbsp;cache it has a TDP of 19&nbsp;W and can be cooled passively. The Celeron 220 is the successor of the Celeron 215 which is based on a Yonah core and used on the D201GLY motherboard. This processor is exclusively used on the mini-ITX boards targeted to the sub-value market segment.

Intel launched the dual core Celeron E1xxx processor line on January 20, 2008, based on the Allendale core. The CPU has 800&nbsp;MT/s FSB, 65&nbsp;W TDP and uses 512&nbsp;KB of the chip's 2&nbsp;MB L2&nbsp;cache, significantly limiting performance for uses such as gaming. New features to the Celeron family included full enhanced halt state and enhanced Intel [[SpeedStep]] technology. Clock rates range from 1.6&nbsp;GHz to 2.4&nbsp;GHz. It is compatible with other Allendale-based CPUs such as the Core 2 Duo E4xxx and Pentium Dual-Core E2xxx.<ref>{{cite news| url=http://www.xbitlabs.com/news/cpu/display/20071011171900.html| title=Intel Preps Dual-Core Celeron Processors| date=October 11, 2007| access-date=November 12, 2007| url-status=dead| archive-url=https://web.archive.org/web/20071104025126/http://www.xbitlabs.com/news/cpu/display/20071011171900.html| archive-date=November 4, 2007| df=dmy-all}}</ref>

==== Wolfdale-3M ====
{{Main|Wolfdale (microprocessor)#Wolfdale-3M}}
The Celeron E3000 series, starting with E3200 and E3300, was released in August 2009, featuring the Wolfdale-3M core used in [[Pentium Dual-Core]] E5000, Pentium E6000 and [[Core 2]] Duo E7000 series. The main difference to Allendale-based Celeron processors is the support for [[Intel VT-x]] and increased performance due to the double L2 Cache of 1&nbsp;MB.
