Initialism of Intel Architecture, 64-bit.

Noun

[edit]

IA-64

  1. (computing) An EPIC 64-bit instruction set architecture designed to allow relatively simple, cheap CPUs to execute many 64-bit instructions simultaneously and with potentially very high performance; developed by Intel in the late 1990s with the intent of replacing the older x86 architecture, but was delayed and proved uncompetitive with x86 (especially x86-64), seeing use only in Intel's own Itanium line of high-end CPUs.
