Intel’s Itanium 64-bit processor product line attempts to design non-x86 for server and enterprise workloads.As of July 29th, Intel has The last batch of Itanium processors Customers, thus ending the era of this processor series.
Intel Itanium is a 64-bit processor family based on IA-64 Instruction Set Architecture (ISA). In a joint venture with Hewlett-Packard (HP), Intel decided to develop a new type of processor to better adapt to modern workloads and implement some new ideas in the field of processor architecture.
Itanium-based systems are strongly promoted by Hewlett-Packard Enterprise (HPE), a branch of HP’s enterprise that produces many server systems containing Itanium processors. HPE says its Itanium-based system “Upright”Several other vendors are also involved in the production of Itanium-based systems, but HP is the main driver of platform growth.
HP even developed its own special user experience Operating system (OS) based on Unix System V. This operating system is used to power HPE Integrity servers running Itanium processors and PA-RISC instruction set architecture, which is also a highly specialized ISA unique to HP.
IA-64 processors promise higher efficiency because they lack the extensive legacy software support that x86 processors have.become a Very long instruction word (VLIW) Architecture, the Itanium architecture relies on the software compiler to pre-calculate which instructions can be executed in parallel, so the processor does not waste instruction cycles.
In theory, this would work well, but in practice, due to the need for a special compiler, it results in limited software support for daily server workloads. HP’s own HP-UX OS support is End with Integrity server Based on Itanium processors, support should be provided before December 31, 2025. On that day, the latest version of HP-UX 11i v3 (B.11.31) will end its life cycle.
Just a few days ago, with the last shipment of the processor family this year, we are witnessing the end of an era that has lasted for more than 20 years. Itanium was launched in July 2001, and the latest version of Itanium 9700 “Kittson” reached its final destination on July 29, when Intel decided to stop further shipments of the Itanium generation. This marks an era when Intel currently uses only the x86-64 architecture in its server processors.
