Itanium never sold well outside enterprise servers and high-performance computing systems, and the architecture was ultimately supplanted by competitor AMD's x86-64 (also called AMD64) architecture. x86-64 is a compatible extension to the 32-bit x86 architecture, implemented by, for example, Intel's own Xeon line and AMD's Opteron line.
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP. The first Itanium processor, codenamed Merced, was released in 2001.
Itanium 2 uses socket PAC611 with a 128 bit wide FSB.The 90 nm CPUs (9000 and 9100 series) bring dual-core chips and an updated microarchitecture adding multithreading and splitting the L2 cache into a 256 KB data cache and 1 MB instruction cache per core (the pre-9000 series L2 cache being a 256 KB common cache).
Itanium processor featuring an all-new microarchitecture. [26] 8 cores, decoupling in pipeline and in multithreading. 12-wide issue with partial out-of-order execution. [27] Kittson the last Itanium. It has the same microarchitecture as Poulson, but slightly higher clock speed for the top two models.
The 10U rx7640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPUs. Maximum of 2 cell boards; 4 CPU sockets per cell board; 16 DIMM slots per cell board; Maximum of 4 SCSI disks and 2 tape and/or CD/DVD-ROM internally (half to each cell board) 7 hot-pluggable I/O slots per cell board plus 1 core I/O slot per cell board ...
It was the basis for Intel and HP development of the Intel Itanium architecture, [3] and HP later asserted that "EPIC" was merely an old term for the Itanium architecture. [4] EPIC permits microprocessors to execute software instructions in parallel by using the compiler, rather than complex on-die circuitry, to control parallel instruction ...

In 2001, prior to its acquisition by Hewlett-Packard, Compaq announced the port of OpenVMS to the Intel Itanium architecture. [64] The Itanium port was the result of Compaq's decision to discontinue future development of the Alpha architecture in favour of adopting the then-new Itanium architecture. [65]
