'''Pentium''' is a semi-discontinued series of [[x86]] architecture-compatible [[microprocessor]]s produced by [[Intel]]. The [[Pentium (original)|original Pentium]] was first released on March 22, 1993. The name "Pentium" is originally derived from the [[Greek language|Greek]] word ''[[wikt:pent-|pente]]'' (''πεντε''), meaning "five", a reference to the prior numeric naming convention of Intel's 80x86 processors (8086–80486), with the [[Latin]] ending ''[[-ium]]'' since the processor would otherwise have been named 80586 using that convention.
 
Pentium was Intel's flagship processor line for over a decade until the introduction of the [[Intel Core]] line in 2006. Pentium-branded processors released from 2009 to 2023 were considered entry-level products that Intel rated as "two stars",<ref>{{cite web |title=Processor Names and Numbers |url=https://www.intel.com/content/www/us/en/processors/processor-numbers.html |website=Intel |language=en-US |access-date=March 26, 2022}}</ref><ref>{{cite web |title=Intel Processors |url=https://www.intel.com/content/www/us/en/products/details/processors.html |website=Intel |language=en-US |access-date=March 26, 2022}}</ref> meaning that they were above the low-end [[Intel Atom|Atom]] and [[Celeron]] series, but below the faster [[Intel Core]] lineup and workstation/server [[Xeon]] series. These later Pentium processors have little more than their name in common with earlier Pentiums.
Line 107 ⟶ 106:
The later Pentiums were based on both the architecture used in [[Intel Atom|Atom]] and that of Core processors. In the case of Atom architectures, Pentiums were the highest performance implementations of the architecture. Pentium processors with Core architectures prior to 2017 were distinguished from the faster, higher-end i-series processors by lower [[clock rate]]s and disabling some features, such as [[hyper-threading]], [[Intel VT|virtualization]] and sometimes L3 [[CPU cache|cache]].
 
In 2017, Intelthe Pentium brand was split Pentiumup into two line-upsseparate lines using the Pentium name:
* Pentium Silver, aiming for low-power devices andusing shares architecture withthe Atom and& Celeron architectures.
* Pentium Gold, aiming for entry-level desktop and using existing architecture,architectures such as [[Kaby Lake]] or [[Coffee Lake]].
 
In September 2022, Intel announced that the Pentium and Celeron brands willwere 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.
