Editing NetBurst (section)

== Successor {{anchor|Future}} ==
Intel had NetBurst-based successors in development called [[Tejas and Jayhawk]] with between 40 and 50 pipeline stages, but ultimately decided to replace NetBurst with the [[Core (microarchitecture)|Core microarchitecture]],<ref>{{Cite web|url=https://www.theregister.com/2004/05/07/intel_kills_tejas/|title=Intel says Adios to Tejas and Jayhawk chips|website=[[The Register]]}}</ref><ref>{{cite web |last1=Goodwins |first1=Rupert |title=Intel cancels Tejas and Jayhawk |url=https://www.zdnet.com/article/intel-cancels-tejas-and-jayhawk/ |website=ZDNet |access-date=21 August 2019 |language=en}}</ref> released in July 2006; these successors were more directly derived from the [[Pentium Pro]] ([[P6 (microarchitecture)|P6 microarchitecture]]). August 8, 2008 marked the end of Intel NetBurst-based processors.<ref>{{Cite web |url=http://www.xbitlabs.com/news/cpu/display/20070521145938.html |title=The Era of Intel's NetBurst Micro-Architecture Comes to End. |first=Anton |last=Shilov |date=May 21, 2007 |website=XbitLabs |access-date=November 29, 2015 |archive-url=https://web.archive.org/web/20151017144944/http://www.xbitlabs.com/news/cpu/display/20070521145938.html |archive-date=October 17, 2015 |url-status=dead}}</ref> The reason for NetBurst's abandonment was the severe heat problems caused by high clock speeds. While some Core- and Nehalem-based processors have higher [[Thermal design power|TDP]]s, most processors are multi-core, so each core gives off a fraction of the maximum TDP, and the highest-clocked Core-based single-core processors give off a maximum of 27 W of heat. The fastest-clocked desktop Pentium 4 processors (single-core) had TDPs of 115 W, compared to 88 W for the fastest clocked mobile versions. Although, with the introduction of new steppings, TDPs for some models were eventually lowered.

The Nehalem microarchitecture, the successor to the Core microarchitecture, was supposed to be an evolution of NetBurst according to Intel roadmaps dating back to 2000.{{citation needed|date=October 2021}} Nehalem reimplements certain features of NetBurst, including the Hyper-Threading technology first introduced in the 3.06&nbsp;GHz ''Northwood'' core, and L3 cache, first implemented on a consumer processor in the ''Gallatin'' core used in the Pentium 4 Extreme Edition.
