context_page_description: Itanium is a family of 64-bit Intel microprocessors that implement the Intel Itanium architecture. Intel marketed the processors for enterprise servers and high-performance computing systems. The Itanium architecture originated at Hewlett-Packard, and was later jointly developed by HP and Intel.
  Itanium-based systems have been produced by HP and several other manufacturers. In 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power ISA, and SPARC.
  In February 2017, Intel released the final generation, Kittson, to test customers, and in May began shipping in volume. It is used exclusively in mission-critical servers from Hewlett Packard Enterprise.
  Intel officially announced the discontinuation of the Itanium CPU family on January 30, 2019.
context_section_description: Although Itanium did attain limited success in the niche market of high-end computing, Intel had originally hoped it would find broader acceptance as a replacement for the original x86 architecture.
  AMD chose a different direction, designing the less radical x86-64, a 64-bit extension to the existing x86 architecture, which Microsoft then supported, forcing Intel to introduce the same extensions in its own x86-based processors. These designs can run existing 32-bit applications at native hardware speed, while offering support for 64-bit memory addressing and other enhancements to new applications. This architecture has now become the predominant 64-bit architecture in the desktop and portable market. Although some Itanium-based workstations were initially introduced by companies such as SGI, they are no longer available.
