it was a looooooooong death.
it was a nice 64 bit but Intel haven't made it evolve since the X64 have risen and were more easy to integrate in company.

Itanium sucked performance wise for the money invested in it. Early chips were atrocious.
I don't know why they don't just take x86_64, strip out all 32bit stuff and backwards compatible things like 8087 emulation, mmx etc. Dropping backwards compatibility would free up loads of transistor space and allow better instruction mapping decisions to be made. Instruction fetching is still one of the main bottlenecks of x86 cpu's due to the horrendously fragmented instruction map.

Shabby means not good. So not so shabby would be not bad.
It's kind of a shame seeing Itanium go, for like the 7th time, because having an alternative out there being actively developed expands possibilities. Everything being forever deadlocked on being x86 derivatives isn't good.

Actually, in the early 90s HP did envision EPIC to eventually become top-down architecture, but their partner (Intel) realized soon that HPC market was the most it will see. Itanium was the typical overly optimistic vision of its time, when skeptics were already declaring the dominant x86 obsolete and unsalable, ready for the grave. The future back in the 90s belonged to PowerPC, Alpha and Itanium -- all of them now burred under billions of x86-compatible CPUs in every possible market segment, while adding ARM on top of the lid.
That doesn't mean x86's cluttered ISA doesn't have to be dusted off at some point in time. There are already steps in compiler development to phase out the legacy x87 stack (together with MMX), since the x86-64 specs already depreciates it, and with AVX Intel finally began to think about smoother integration of future ISA extensions and register formats, by using prefixes.
