Itanium is aimed at the enterprise server and high-performance computing (HPC) markets. Other enterprise- and HPC-focused processor lines include Oracle Corporation's SPARC M7, Fujitsu's SPARC64 X+ and IBM's POWER8. Measured by quantity sold, Itanium's most serious competition comes from x86-64 processors including Intel's own Xeon line and AMD's Opteron line. Since 2009, most servers were being shipped with x86-64 processors.
