Is IA-64 dead?

Is IA-64 dead?
With no more new Itanium processors in the pipeline, it looks like the family of IA-64 is dead. Intel largely gave up on Itanium and developed EM64T, better known as Intel64. With HP set to support Itanium systems until 2025, this will be the last hurrah as the company stocks up for the end.
What is IA-64 bit?
IA-64 is the Intel Itanium Architecture. This is a Very Long Instruction Word (VLIW) processor instruction set. x86_64 is the normal 64-bit architecture that is used by processors inside every laptop / desktop in today’s computers. This processor is a dynamic processor.
What is the main difference between x64 and IA-64?
According to this page: IA64 refers to the 64 bit Itanium architecture while x64 is the 64 bit extension to the x86 architecture. The IA64 is exclusive to Intel while x64 is used by all. IA64 was intended for high-end server applications while x64 was initially intended for desktops but were scaled up.
What processors use the IA-64 instruction set?
In all Itanium models, up to and including Tukwila, cores execute up to six instructions per clock cycle….IA-64.
| Encoding | Fixed |
| Branching | Condition register |
| Endianness | Selectable |
| Registers | |
|---|---|
| General purpose | 128 (64 bits plus 1 trap bit; 32 are static, 96 use register windows); 64 1-bit predicate registers |
What is an Itanium based system?
Itanium (/aɪˈteɪniəm/ eye-TAY-nee-əm) is a discontinued family of 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). Itanium-based systems were produced by HP/Hewlett Packard Enterprise (HPE) (the HPE Integrity Servers line) and several other manufacturers.
