IA-64 is an architecture of Intel itanium. It is used in computing systems of high performance and in enterprise servers. AMD64 happens to be an instruction set that is in a direct contest of IA-64 architecture. IA-64 is just based on level parallelism of explicit instruction; the whole AMD64 performs in both legacy mode and long mode. Few other features of the IA-64 architecture that make it different from the AMD64 architectural design are the integer capability of 64 bit, additional registers, removal of old features, additional XMM registers, bigger physical address space, SSE instructions, bigger virtual address space, no executive bit, and relative data access which points out instruction.

AMD64, on the other hand, functions in such a way that the processor's native 64-bit mode, 16-bit compatibility mode, and a combined 32 bit, which makes the processor act as *86 processor. AMD64 was designed as an alternative to the HP and Intel IA-64.

Intel is a company that makes microprocessors. If there is a high computing need, then this would be the best server and type to use. Both AMD64 and IA-64 were made from different companies. IA-64 was made from Intel and AMD64 was made from Athlon. Both of these use a 64 bit architecture, but the AMD64 wanted to create a new one using the same architecture.

The purposes of these two things are quite different. The AMD64 is used as an instruction set and is the competitor of the IA-64 and the IA-64 is used as an enterprise server and high performance computing system. Hewitt Packard is credited with beginning the architectures that are now being implemented into these new systems.
