The reference to "EFI" in instruction set is technically incorrect. EFI is a specification that governs a replacement for system BIOS it applies to any architecture, not IPF in particular. The code that supplements an IPF processor is call the PAL/SAL for Processor Abstraction Layer/System Abstraction Layer. I will change this shortly if nobody objects. --Metadynamics 23:17, 7 October 2005 (UTC)


Would it be appropriate to mention AMD's version of the 64-bit architecture? Specifically how AMD will not follow the lead of Intel, and will instead extend the x86 based design into 64 bits. --seav 21:50, Oct 21, 2003 (UTC)

Possibly as a competitor. It's hard to write much about it while the battle is running hot. - David Gerard 11:16, Jan 25, 2004 (UTC)

This article is largely redundant with Itanium - is there actually a difference anyone outside Intel marketing cares about? Should one be folded into the other? - David Gerard 11:16, Jan 25, 2004 (UTC)

Unless anyone strenuously objects (and is willing to work to differentiate the two articles effectively), I'll be merging this with Itanium in a few days - David Gerard 18:16, Mar 29, 2004 (UTC)

Merger with Itanium article[edit]

Did this IA-64 article ever get merged into the Itanium article?

Per the discussion in the talk page for Itanium, this should not be merged as it applies to the IA64 architecture, not the Itanium product as sold by Intel. If anything the Itanium and Itanium2 pages should be merged, even though they are generationally distict they are logically continuous.--Metadynamics 23:17, 7 October 2005 (UTC)

IA-64 and Apple[edit]

Is this also the same instruction set that Apple Computer will port into? If yes, it should be in the article.

Answer: No, it is not.

IA-32 Execution Layer[edit]

Perhaps the developments around the IA-32 Execution Layer could be added to the part regarding IA-32 Support?

Isn't IA-64 dead?[edit]

I thought Intel had given up on IA-64 and switched to making x86-64 go faster. If that's true, it should be reflected in this article. (sorry, I don't have a reference at hand) --Alvestrand 22:26, 8 December 2006 (UTC)

No they have not, as of Feb 2007. Please see Itanium 2. The fact that apparently everybody in the industry thinks that they should just give it up does not mean that they have given it up. See Intel iAPX 432 for the last time this happened. - Arch dude 23:01, 6 February 2007 (UTC)
I think the relationship between IA-64 and x86-64 is just like yesterday's Windows NT and Windows 9x(95, 98 and Me). For years, Windows NT 4.0 stay in the silent, but Windows 9x was popular and many following editions released. But one day Windows XP arrived, everything changed. I think Itanium Architecture is just like yesterday's Windows NT, and eventually would take over the all the x86 market to arrive on everyone's desktop. Janagewen (talk) 03:24, 23 August 2014 (UTC)
Far from "just like". Microsoft was always planning to bring the 9x users into the NT family; you can see that in roadmaps they published as early as 94. Whereas, there has never been a roadmap or anything else from Intel that suggests they are even thinking about introducing Itanium to the typical desktop (not, at least, since the wild success of AMD64, followed by Intel's grudgingly following suit). Heck, with the performance increases seen by x64, Itanium is not even much of a contender in the workstation market. It is inherently a much higher cost architecture to make chips for than x86/x64, so it's never going to be able to compete at the low end. Jeh (talk) 23:17, 31 August 2014 (UTC)
Janagewen... you don't have to strike something out just because someone has disagreed with you! Jeh (talk) 22:45, 2 September 2014 (UTC)
Nowadays more and more software and hardware manufacturers stall support for it, but through its outstanding design, there is no equivalent replacement to it. So at this point, the future Itanium might need a hybrid change, leaving the x86 support on the level of decoder on microarchitecture, rather than on the firmware or OS level. Hybriding the x86 and Itanium codes together when running on IA-32 OS might be the potential future view of it. In other words, not let OS aware of the Itanium codes, but Itanium itself could manipulate themselves, when working under IA-32 or x64 OSes. When working under pure Itanium mode OS, x86 support could be removed at all. From Pentium through Core i7, Intel is definitively the proficient microarchitecture designer. So I think IA-64 is not dead at all, but like roses grow themselves up in the long cold winters. I do apologize for my fantasy guess. Janagewen (talk) 22:20, 15 September 2014 (UTC)
I should do my apologize to this guy, Jeh, that there might be something wrong with internet connection when I post my last reply. So that might be the reason cause something not right here. And this time I fix it. I've no purpose to make any damage or interference of what other's writes. But Jeh, how you make warning to me, that is the business of your own. But for more than that, I think one should respect to him/herself on Wikipedia.org first of all... Janagewen (talk) 05:25, 16 September 2014 (UTC)

Needs more sources[edit]

I think this article needs more sources. Whole sections do not cite a single source. New guy 01:12, 31 December 2006 (UTC)

Request for comment: consolidated article[edit]

I have attempted to write a consolidated article, capturing all the important stuff from Itanium, Itanium 2, and IA-64, with the intent of replacing the three with one article named Itanium.

The proposed article is in my workspace. Please review and comment. (Comments on the proposed article's talk page, please.)

In addition to simplification and consolidation, I have attempted to add citations wherever I could, and I have removed some material that I could not find citations for. The article is basically a complete rewrite, but almost everything in it is from the original articles, with two major exceptions:

  • The material on the architecture is considerably more detailed and focused on architecture.
  • I added a timeline, moved many statements to the timeline, and added material to it.

The form of the citations still needs work, and we need still more citations. We are still missing a lot of history from the timeline,(mostly 1994-1997) and we are missing a paragraph in the "History" section abou tthe period from 2002 to present.However, this is material that is not present in the current articles either.

Thanks.-Arch dude 23:05, 19 March 2007 (UTC)

UPDATE: Colleagues, the WP:MERGE guideline is that a proposed merge can be completed after a two-week discussion period if consensus is reached, or after a four-week period if no comments are received. So far, there are no comments. I intend to perform the merger on or about 16 april if there are still no comments by then , but I would really prefer to have someone review the proposed new article. -Arch dude 18:28, 30 March 2007 (UTC)

It would be nice for the current status of IA-64 to be made clear[edit]

The introduction ends with, "As of 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power Architecture, and SPARC."

The History section's last subsection is, "Itanium 9500 (Poulson): 2012".

I resorted to using my browser's page search functionality to search for successive years: "2013", "2014", "2015".

It would be nice if the article made the current status of IA-64 more clear and/or more obvious.

Thanks for reading! 173.13.156.125 (talk) 07:45, 23 April 2015 (UTC)

As was the case on Itanium, the first of those references, and I fixed the reference to point to its new location. The second one's Wayback Machine location works. Guy Harris (talk) 21:01, 27 February 2016 (UTC)

Do we need to duplicate Itanium in the History section?[edit]

Processor details are already covered in Itanium, and that coverage is more up-to-date. Perhaps we should just quickly summarize the various IA-64/Itanium implementations here, leaving the details to Itanium. Guy Harris (talk) 20:51, 30 April 2017 (UTC)

Both Itanium and IA-64 are the architecture name, why not merge them together? — Preceding unsigned comment added by 119.53.118.176 (talk) 22:21, 30 April 2017 (UTC)
