In September 2022, Intel announced that the Pentium and Celeron brands were to be replaced with the new "Intel Processor" branding for low-end processors in laptops from 2023 onwards.<ref name="Warren 2022"/> This also applied to desktops using Pentium processors, and they were discontinued around the same time laptops stopped using Pentium processors in favor of "Intel Processor" processors in 2023.
== Overview ==
{{See also|List of Intel Pentium processors}}
During development, Intel generally identifies processors with [[codename]]s, such as ''Prescott'', ''Willamette'', ''Coppermine'', ''Katmai'', ''Klamath'', or ''Deschutes''. These usually become widely known,<ref>{{Cite web |title=Names of processors |url=http://www.ece.iastate.edu/~morris/cs570/name.html |website=IA State}}</ref> even after the processors are given official names on launch.
The original Pentium-branded CPUs were expected to be named 586 or i586, to follow the naming convention of prior generations ([[Intel 80286|286]], [[Intel 80386|i386]], [[Intel 80486|i486]]). However, as the firm wanted to prevent their competitors from branding their processors with similar names (as AMD had done with their [[Am486]]), Intel filed a [[trademark]] application on the name in the United States, but was denied because a series of numbers was considered to lack ''[[trademark distinctiveness]]''.<ref name="newyorker">{{cite news |last=Colapinto |first=John |author-link=John Colapinto |date=October 3, 2011 |title=Famous names |language=en-US |pages=38–43 |work=The New Yorker |url=http://www.newyorker.com/reporting/2011/10/03/111003fa_fact_colapinto |access-date=October 12, 2011}}</ref>
Following Intel's prior series of [[8086]], [[80186]], [[80286]], [[80386]], and [[80486]] microprocessors, the firm's first P5-based processor was released as the [[P5 (microarchitecture)|original Intel Pentium]] on March 22, 1993. Marketing firm [[Lexicon Branding]] was hired to coin a name for the new processor. The suffix ''-ium'' was chosen as it could connote a fundamental ingredient of a computer, like a [[chemical element]],<ref>{{cite news |last=Burgess |first=John |date=October 20, 1992 |title=Intel's fifth-generation chip no longer goes by the numbers |language=en-US |work=The Washington Post |url=https://www.washingtonpost.com/archive/business/1992/10/20/intels-fifth-generation-chip-no-longer-goes-by-the-numbers/cbf117ef-23b8-4f48-bfc6-70faaecaf298/ |access-date=December 22, 2022}}</ref> while the prefix ''[[pent-]]'' could refer to the fifth generation of x86.<ref name="newyorker" />
Due to its success, the Pentium brand would continue through several generations of high-end processors. In 2006, the name briefly disappeared from Intel's [[technology roadmap]]s,<ref>{{cite news |last=Huynh |first=Anh Tuan |date=September 20, 2006 |title=Intel "Conroe-L" Details Unveiled |website=DailyTech |url=http://www.dailytech.com/article.aspx?newsid=4252 |url-status=dead |access-date=August 16, 2007 |archive-url=https://web.archive.org/web/20120306021304/http://www.dailytech.com/article.aspx?newsid=4252 |archive-date=March 6, 2012}}</ref><ref name="Feature - Computers - CNET Asia">{{cite web |last1=Thatcher |first1=Michelle |last2=Brown |first2=Rich |date=April 23, 2008 |title=The multicore era is upon us |url=http://asia.cnet.com/the-multicore-era-is-upon-us-61998152.htm |url-status=dead |archive-url=https://archive.today/20130119125038/http://asia.cnet.com/the-multicore-era-is-upon-us-61998152.htm |archive-date=January 19, 2013 |access-date=May 7, 2017 |website=CNET |language=en-US}}</ref> only to re-emerge in 2007.<ref>{{cite news |date=August 6, 2007 |title=Intel to unify product naming scheme |website=TG Daily |url=http://www.tgdaily.com/content/view/33234/122/ |url-status=dead |access-date=August 12, 2007 |archive-url=https://web.archive.org/web/20070926232224/http://www.tgdaily.com/content/view/33234/122/ |archive-date=September 26, 2007}}</ref>

In 2009, the "Dual-Core" suffix was dropped, and new x86 processors started carrying the plain ''Pentium'' name again.
In 2014, Intel released the ''Pentium 20th Anniversary Edition'', to mark the 20th anniversary of the Pentium brand. These processors are unlocked and highly overclockable.
In 2017, Intel split the Pentium branding into two line-ups. Pentium Silver targets low-power devices and shares architecture with Atom and Celeron, while Pentium Gold targets entry-level desktops and uses existing architecture, such as [[Kaby Lake]] and [[Coffee Lake]].
In September 2022, Intel announced that the Pentium and Celeron brands were to be replaced with the new "Intel Processor" branding for low-end processors in laptops from 2023 onwards.<ref name="Warren 2022" /> This also applied to desktops using Pentium and Celeron processors, and both brands were discontinued as planned in 2023 in favor of "Intel Processor" branded processors.

=== P5 microarchitecture based ===
The original ''[[P5 (microarchitecture)|Intel P5]]'' or ''Pentium'' and ''[[Pentium MMX]]'' processors were the [[superscalar]] follow-on to the [[80486]] processor and were marketed from 1993 to 1999. Some versions of these were available as [[Pentium OverDrive]] that would fit into older [[CPU socket]]s.

[[File:A80502100 sy007 pentium observe.png|thumb|A 100 MHz Pentium ([[iCOMP (index)|ICOMP]]=815) processor manufactured in 1996|left]]
In parallel with the P5 microarchitecture, Intel developed the ''[[P6 (microarchitecture)|P6 microarchitecture]]'' and started marketing it as the ''[[Pentium Pro]]'' for the high-end market in 1995. It introduced [[out-of-order execution]] and an integrated second-level [[CPU cache|cache]] on dual-chip processor package.
The second P6 generation replaced the original P5 with the ''[[Pentium II]]'' and rebranded the high-end version as ''[[Pentium II Xeon]]''. It was followed by a third version named the ''[[Pentium III]]'' and ''[[Pentium III Xeon]]'' respectively. The Pentium II line added the [[MMX (instruction set)|MMX]] instructions that were also present in the Pentium MMX.
Versions of these processors for the laptop market were initially named ''Mobile Pentium II'' and ''Mobile Pentium III'', later versions were named ''Pentium III-M''. Starting with the Pentium II, the [[Celeron]] brand was used for low-end versions of most Pentium processors with a reduced feature set such as a smaller cache or missing power management features.

===NetBurst microarchitecture based===
In 2000, Intel introduced a new microarchitecture named ''[[NetBurst]]'', with a much longer pipeline enabling higher clock frequencies than the P6-based processors. Initially, these were named ''[[Pentium 4]]'', and the high-end versions have since been named simply [[Xeon]]. As with Pentium III, there are both ''Mobile Pentium 4'' and ''Pentium 4 M'' processors for the laptop market, with Pentium 4 M denoting the more power-efficient versions. Enthusiast versions of the Pentium 4 with the highest [[clock rate]]s were named ''[[Pentium 4#Gallatin (Extreme Edition)|Pentium 4 Extreme Edition]]''.
The ''[[Pentium D]]'' was the first [[multi-core]] Pentium, integrating two Pentium 4 chips in one package and was available as the enthusiast ''[[Pentium Extreme Edition]]''.

===Pentium M microarchitecture based===
In 2003, Intel introduced a new processor based on the P6 microarchitecture named ''[[Pentium M]]'', which was much more power-efficient than the Mobile Pentium 4, Pentium 4 M, and Pentium III M. Dual-core versions of the Pentium M were developed under the code name ''[[Yonah (microprocessor)|Yonah]]'' and sold under the marketing names ''[[Core Duo]]'' and ''[[Pentium Dual-Core]]''. Unlike Pentium D, it integrated both cores on one chip. From this point, the [[Intel Core]] brand name was used for the mainstream Intel processors, and the Pentium brand became a low-end version between Celeron and Core. All Pentium M based designs including Yonah are for the mobile market.

===Core microarchitecture based===
The ''[[Pentium Dual-Core]]'' name continued to be used when the Yonah design was extended with 64-bit support, now named the ''[[Core (microarchitecture)|Core microarchitecture]]''. This eventually replaced all NetBurst-based processors across the four brands Celeron, Pentium, Core, and Xeon. Pentium Dual-Core processors based on the Core microarchitecture use the [[Conroe (microprocessor)#Allendale|Allendale]] and [[Wolfdale (microprocessor)|Wolfdale]]-3M designs for desktop processors and [[Merom (microprocessor)|Merom]]-2M for mobile processors.

In 2009, Intel changed the naming system for Pentium processors, renaming the Wolfdale-3M based processors to ''Pentium'', without the Dual-Core name, and introduced new single- and dual-core processors based on [[Penryn (microprocessor)|Penryn]] under the Pentium name.
The Penryn core is the successor to the Merom core and Intel's 45 nm version of their mobile series of Pentium processors. The FSB frequency is increased from 667 MHz to 800 MHz, and the voltage is lowered. Intel released the first Penryn Core, the Pentium T4200, in December 2008. In June 2009, Intel released the first single-core processor to use the Pentium name, a [[Consumer Ultra-Low Voltage]] (CULV) Penryn core named Pentium SU2700.
In September 2009, Intel introduced the Pentium SU4000 series together with the Celeron SU2000 and Core 2 Duo SU7000 series, which are dual-core CULV processors based on Penryn-3M and using 800 MHz FSB. The Pentium SU4000 series has 2 MB L2 cache but is otherwise basically identical to the other two lines.
===Nehalem microarchitecture based===
{{Main|List of Intel Pentium processors}}
The [[Nehalem (microarchitecture)|Nehalem]] microarchitecture was introduced in late 2008 as a successor to the Core microarchitecture, and in early 2010, a new ''Pentium'' G6950 processor based on the ''[[Clarkdale (microprocessor)|Clarkdale]]'' design was introduced based on the ''[[Westmere (CPU)|Westmere]]'' refresh of Nehalem, which were followed by the mobile P6xxx based on [[Arrandale (microprocessor)|Arrandale]] a few months later.

On January 7, 2010, Intel launched a new Pentium model using the Clarkdale chip in parallel with other desktop and mobile CPUs based on their new Westmere microarchitecture. The first model in this series is the Pentium G6950. The Clarkdale chip is also used in the Core i3-5xx and Core i5-6xx series and features a 32 nm process (as it is based on the Westmere microarchitecture), integrated memory controller and 45 nm graphics controller and a third-level cache. In the Pentium series, some features of Clarkdale are disabled, including [[AES New Instructions|AES-NI]], [[hyper-threading]] (versus Core i3), and the graphics controller in the Pentium runs at 533 MHz, while in the Core i3 i3-5xx series they run at 733 MHz, and Dual Video Decode that enables Blu-ray picture-in picture hardware acceleration, and support for Deep Color and [[xvYCC]].{{Citation needed|date=July 2010}} The memory controller in the Pentium supports DDR3-1066 max, the same as the Core i3 i3-5xx series.<ref>{{cite web |url=http://ark.intel.com/products/43529 |title=Intel Core i3-350M Processor (3M Cache, 2.26 GHz) Product Specifications }}</ref> The L3 cache is also 1 MB less than in the Core i3-5xx series.
