Itanium was a RISC-y endeavour by Intel and it had it's problems but you can't really say it died because of x86_64. Microsoft adopted it and dropped IA-64 like a hot potato. Intel dropped Yamhill and other projects that attempted to bring IA-64 to the desktop as soon as they realized MS wanted x86-64. Performance didn't factor in because AMD would have never had the chance to provide the world all the CPUs it wanted (supply constraints)

I think you are mixing a few things here Yamhill was supposed to be a x86_64 CPU (under license from AMD) it was dropped in favor of promoting Intels own IA64 instead. http://www.geek.com/chips/intels-otellini-says-no-to-yamhill-549157/ http://www.geek.com/chips/intels-otellini-says-no-to-yamhill... Microsoft dropped support for IA64 only a few years ago with Windows Server 2008 R2 being the last OS that supported it due to the limited market share. This was quite long after Intel has killed IA64 internally on it's own.
