Editing Tukwila (processor)

{{update|date=October 2015}}
The '''Itanium 9300''' series, code-named '''''Tukwila''''', is the generation of [[Intel]]'s [[Itanium]] processor family following [[Itanium 2]] and [[Montecito (processor)|Montecito]]. It was released on 8 February 2010. It utilizes both multiple [[processor core]]s ([[Multi-core (computing)|multi-core]]) and [[Simultaneous multithreading|SMT]] techniques. The engineers said to be working on this project were from the [[DEC Alpha]] project, specifically those who worked on the [[Alpha 21464]] (EV8), which was focused on SMT.

Named for the city of [[Tukwila, Washington]], Tukwila was previously code-named ''Tanglewood''. The original name is also used by the [[Tanglewood|Tanglewood music festival]], and Intel renamed the project in late 2003.<ref>{{cite web| url=http://news.cnet.com/Intel-changes-code-name-of-future-Itanium/2100-1006_3-5129242.html| title=Intel changes code name of future Itanium| author=Michael Kanellos| date=December 18, 2003}}</ref>

The processor has two to four cores per die and up to 24 MB L3 of on-die cache.
They are the first batch of processors to contain more than 2 billion [[transistors]] on a single die.<ref>{{cite news| url=http://news.bbc.co.uk/2/hi/technology/7223145.stm| title=Chips pass two billion milestone| author=BBC News| author-link=BBC News| date=February 4, 2008}}</ref><ref>{{cite web|url=http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9060900&intsrc=hm_list |title=Intel squeezes 2 billion transistors onto new Itanium chip |accessdate=2008-02-05 |author=Sharon Gaudin |date=2008-02-04 |work=[[Computerworld]]}}</ref> This total is made up as follows:<ref>[https://arstechnica.com/hardware/news/2008/02/intel-shows-off-tukwila-first-2-billion-transistor-cpu.ars Intel shows off Tukwila, first 2 billion transistor CPU]</ref>

* core [[digital circuit|logic]] — 430 million
* system interface — 157 million
* L3 cache — 1,420 million
* [[input/output|I/O]] logic — 39 million
* chip total — 2.046 billion

Die size is 21.5×32.5&nbsp;mm or 698.75&nbsp;mm<sup>2</sup>.

==Xeon compatibility==
It was originally stated that Tukwila and its associated chipset would bring socket compatibility between Intel's [[Xeon]] and Itanium processors, by introducing a new interconnect called [[Intel QuickPath Interconnect]] (QuickPath, previously known as Common System Interface or CSI). This ultimate endeavor would help reduce product development costs for both Intel and its partners, by allowing for greater reuse of components and manufacturing processes.<ref>{{cite magazine| url=http://www.pcworld.com/news/article/0,aid,123190,00.asp| title=Intel Changes CPU Road Map| date=October 25, 2005| magazine=[[PC World (magazine)|PC World]]| access-date=October 26, 2005| archive-date=May 16, 2008| archive-url=https://web.archive.org/web/20080516112152/http://www.pcworld.com/news/article/0,aid,123190,00.asp| url-status=dead}}</ref> Tukwila is reported to have four "full" QuickPath links and two "half" links.<ref>{{cite web| url=http://www.realworldtech.com/page.cfm?NewsID=361&section=news&date=05-05-2006#361| title=Intel's Tukwila Confirmed to be Quad Core| date=5 May 2006| url-status=dead| archive-url=https://web.archive.org/web/20090113081149/http://www.realworldtech.com/page.cfm?NewsID=361&section=news&date=05-05-2006#361| archive-date=13 January 2009}}</ref>

Whitefield, the first Xeon processor to feature QuickPath, suffered significant project delays and was cancelled.<ref>{{cite web| url=https://www.theregister.co.uk/2005/12/12/intel_csi_low/| title=Intel's CSI to outperform AMD's Hypertransport| date=12 December 2005| website=[[The Register]]}}</ref> The first Xeon MP processor to feature QuickPath is [[Xeon#Beckton|Beckton]].<ref name="DailyTech Server">{{cite news| url=http://www.dailytech.com/Intel+Aims+for+Efficiency+With+New+Server+Roadmap/article14224.htm| first=Jansen| last=Ng| title=Intel Aims for Efficiency With New Server Roadmap| date=10 February 2009| work=[[DailyTech]]| access-date=2009-02-10| url-status=dead| archive-url=https://web.archive.org/web/20090213150005/http://www.dailytech.com/intel+aims+for+efficiency+with+new+server+roadmap/article14224.htm| archive-date=13 February 2009}}</ref>

The released Itanium 9300-series processors are using a separate socket, [[LGA 1248]], which is incompatible with Xeon processors and motherboards.

==Successor==
The successor is code-named ''[[Poulson (processor)|Poulson]]''. It was initially slated for a Q4 2009 release and said to have over four cores, most likely eight.<ref>[http://pc.watch.impress.co.jp/docs/2008/0602/kaigai02l.gif Intel Server and Workstation Roadmap] Image</ref><ref>Ashlee Vance (11 July 2008). [https://www.theregister.co.uk/2008/07/11/ibm_power7_ncsa/ "IBM's eight-core Power7 chip to clock in at 4.0GHz"]. ''[[The Register]].''</ref>

In 2009 an Intel representative stated that Intel would maintain a two-year development cycle for Itanium, implying Poulson would be released in Q1 2012.<ref>{{cite web| url=http://www.computerworld.com/s/article/9138420/Intel_ahead_of_schedule_with_new_Xeon_server_chips| title=Intel ahead of schedule with new Xeon server chips| date=2009-09-22| work=[[Computerworld]]| access-date=2010-01-10| archive-date=2011-06-05| archive-url=https://web.archive.org/web/20110605143255/http://www.computerworld.com/s/article/9138420/Intel_ahead_of_schedule_with_new_Xeon_server_chips| url-status=dead}}</ref>
