What is "itanium"

Itanium is a family of 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). Intel markets the processors for enterprise servers and high-performance computing systems. The Itanium architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel.

Itanium-based systems have been produced by HP (the HP Integrity Servers line) and several other manufacturers. , Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power Architecture, and SPARC. The Poulson processor was released on November 8, 2012. While Intel said in April 2015 that it continued to work on Poulson's successor, Kittson, Poulson was the most recent processor available, Hewlett-Packard was the only customer; even HP had introduced Xeon-based machines, and it appeared that Kittson would be the last Itanium.
