The Itanium was no longer superior to contemporaneous RISC and CISC processors. Itanium competed at the low-end (primarily 4-CPU and smaller systems) with servers based on x86 processors, and at the high end with IBM's POWER architecture and Sun Microsystems' SPARC architecture. Intel repositioned Itanium to focus on high-end business and HPC computing, attempting to duplicate x86's successful "horizontal"  market.  With economies of scale fueled by its enormous installed base, x86 was the preeminent "horizontal" architecture in enterprise computing. HP and Intel recognized that Itanium was not competitive and replaced it with Itanium 2 a year later, as they had planned. Only a few thousand of the original Itaniums were sold, due to limited availability caused by poor yields, relatively poor performance, and high cost.

On this side view you can read the words
"Intel Confidential". This means that this Processor is a Engineering Sample.
