In 1989, HP started to research an architecture that would exceed the expected limits of the reduced instruction set computer (RISC) architectures caused by the great increase in complexity needed for executing multiple instructions per cycle due to the need for dynamic dependency checking and precise exception handling. In an article titled "Intel's Itanium is finally dead: The Itanic sunken by the x86 juggernaut" Techspot declared "Itanium's promise ended up sunken by a lack of legacy 32-bit support and difficulties in working with the architecture for writing and maintaining software" while the dream of a single dominant ISA would be realized by the AMD64 extensions. Since 2009, most servers were being shipped with x86-64 processors, and they dominate the low cost desktop and laptop markets which are were not initially targeted by Itanium. Itanium never sold well outside enterprise servers and high-performance computing systems, and was ultimately replaced by Itanium's most serious competition which came from x86-64 processors which were designed by rival AMD as a compatible extension to the 32 bit X86 including Intel's own Xeon line and AMD's Opteron line. In 2019, Intel announced that new orders for Itanium would be accepted until January 30, 2020, and shipments would cease by July 29, 2021. It was used exclusively in mission-critical servers from Hewlett Packard Enterprise. In February 2017, Intel released the final generation, Kittson, to test customers, and in May began shipping in volume. In 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power ISA, and SPARC. Itanium-based systems were produced by HP/ Hewlett Packard Enterprise (HPE) (the HPE Integrity Servers line) and several other manufacturers. Emulation to run existing x86 applications and operating systems was particularly poor. When first released in 2001, Itanium's performance was disappointing compared to better-established RISC and CISC processors. In the concept phase, engineers said "we could run circles around PowerPC, that we could kill the x86." Early predictions were that IA-64 would expand to the lower-end servers, supplanting Xeon, and eventually penetrate into the personal computers, eventually to supplant RISC and complex instruction set computing (CISC) architectures for all general-purpose applications. Launched in June 2001, Intel initially marketed 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.
