A nice account of how #Intel spent far too much time & money with #HP on the doomed #Itanium 64-bit #CPU, only to be beaten by #AMD with #Athlon (with help from #Microsoft):

Hey #Intel and other hashtags!
What was your thoughts on #IntelItanium or #IA64 and what was your experience if you had any? I’ve not had any personal experience, but I’m curious to hear yours!
Can’t wait to read!

У VLIW длиннее x86: Itanium в шаге от величества, Эльбрус — подержите моё пиво, тайны PS2
Разбираем архитектуру VLIW (Very Long Instruction Word). Поговорим о предтечах, погрузимся в дух 1980-1990-х, узнаем, как Itanium стал Itanic’ом, как архитектура жила, живёт и будет жить. Ах да, будет про Эльбрус и даже PlayStation 2. Осторожно: текст большой, интересный и может заставить вас пересмотреть взгляды на процессорные архитектуры. Дропдаун

Chip Designers Recall the Big AMD-Intel Battle Over x86-64 Support - Slashdot
Link
📌 Summary: 這篇文章探討了一段有趣的硬體歷史，尤其是從AMD和Intel之間的競爭中得出的啟示。AMD工程師Phil Park分享了一位前Intel工程師Robert Colwell的Quora回答，顯示出如果Intel沒有專注於x64的Itanium系列處理器，或許能夠在x86-64架構上先於AMD發展。Colwell透露，Intel內部對於開發64位x86功能持有保守態度，擔心會損害Itanium的市場表現。最終，AMD成功推出x86-64架構，使其在市場上獲勝，而Intel則在隨後的產品中跟進。
🎯 Key Points:
- Intel內部曾因擔心影響Itanium，而不開發64位x86架構，這是一個市場策略的決策。
- Robert Colwell被要求停止推動x86的64位需求，但他留下了可隨時啟用的設計。
- AMD在市場上成功推出x86-64架構，最終使其在競爭中獲勝。
- 當x86-64架構戰勝Itanium時，Intel曾請求Microsoft支持其架構變更，但遭到拒絕。
- Phil Park認為Colwell的謀略在長期中得到了證明。

I submitted a crazy low offer (relative to market) on an Itanium server and won. The collection of shitty computer architectures that can run Windows is complete!
Get ready for some #PowerShell and #VBScript on #Itanium, folks!
(I also have an AlphaStation, Alpha architecture)

And with that, #Itanium aka #IA64/IA-64 support is gone from the #Linux #kernel:
https://git.kernel.org/torvalds/c/1e0c505e13162a2abe7c984309cfe2ae976b428d
https://git.kernel.org/torvalds/c/cf8e8658100d4eae80ce9b21f7a81cb024dd5057 (that's the main removal patch, which is about ~2 MByte big)
Bye bye!

[Windows] NT was initially developed not on x86 chips but a new Intel architecture called the i860 – codenamed N-Ten or NT for short.
...As Cutler and his team discovered, though, while the #i860 could be a fast and efficient graphics processor, it was a three-legged dog for multitasking operating systems like NT. #Intel expected its dominance to see a bad system through enough iterations for the market to both help to fix things in software and be won over.
...#Microsoft dutifully ported its core #Windows #NT server code to #Itanium to find it too was a three-legged dog, only perhaps with not quite so many legs and laughable backwards compatibility. Never mind, thought Intel, the market will wait for a few iterations, help build the code base, and be won over.
A great concise blow-by-blow of how Intel's lack of vision and failure to successfully innovate caused it to lose its dominance in the PC market.
Meanwhile, AMD sidled up to Microsoft and asked if it was interested in 64-bit extensions to IA-32. Ones with a full complement in the legs department and total compatibility. Cutler and co. signed up on the spot. The result was so successful that Intel was forced to adopt its rival's innovation and let Itanium sink without trace. -

#Linux 6.7 Set To Drop Support For #Itanium #IA64
There is also a build fix so at least Linux 6.6, which is expected to be this year's Long Term Support (LTS) kernel release will at least have IA-64 support in good standing should anyone actually use it.
https://www.phoronix.com/news/Linux-6.7-To-Drop-Itanium-IA-64 -
A nearly 2 MByte big patch to remove #Itanium (#IA64) architecture support from the #LinuxKernel is now in #Linux-next and thus (for now) slated for #kernel 6.7:
Before it hit that tree, it was discussed on #LKML a week ago:
