Editing SSE2 (section)

==CPU support==
SSE2 is an extension of the [[IA-32]] architecture, based on the [[x86 instruction set]]. Therefore, only x86 processors can include SSE2. The [[AMD64]] architecture supports the [[IA-32]] as a compatibility mode and includes the SSE2 in its specification.<ref>{{cite web|last=Matz|first=Michael|title=System V Application Binary Interface - AMD64 Architecture Processor Supplement - Draft Version 0.99.4|url=https://www.cs.washington.edu/education/courses/351/12wi/supp-docs/abi.pdf|access-date=April 26, 2013|author2=Hubicka, Jan|author3=Jaeger, Andreas|author4=Mitchell, Mark|date=January 2010}}{{Dead link|date=December 2021 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{cite web|last=Fog|first=Agner|title=Optimizing software in C++: An optimization guide for Windows, Linux and Mac platforms|url=http://www.agner.org/optimize/optimizing_cpp.pdf|access-date=April 26, 2013|archive-date=April 8, 2013|archive-url=https://web.archive.org/web/20130408125402/http://www.agner.org/optimize/optimizing_cpp.pdf|url-status=live}}</ref> It also doubles the number of XMM registers, allowing for better performance.

The following IA-32 CPUs support SSE2:

* [[Intel]] [[NetBurst]]-based CPUs ([[Pentium 4]], [[Xeon]], [[Celeron]], [[Pentium D]], [[Celeron D]])
* Intel [[Pentium M]] and [[Celeron M]]
* [[Intel Atom]]
* [[AMD Athlon 64]]
* [[Transmeta Efficeon]]
* [[VIA C7]]

The following IA-32 CPUs were released after SSE2 was developed, but did not implement it:

* [[AMD]] CPUs prior to [[Athlon 64]], such as [[Athlon XP]]
* [[VIA C3]]
* [[Transmeta Crusoe]]
* [[Intel Quark]]
