You are woefully misinformed. First, IA64 Itanium is alive and well, although market share is lower than Intel would like. Intel sells chips based on both ISAs, x86-64 (Core, Xeon) and IA64 (Itanium) but into different markets. Second, from the Itanium 2 Montecito core forward, hardware support for the IA32 instruction set was removed and replaced by a software emulator with much better performance (though few, if any, customers use it). The current IA64 chip, the Itanium 9300 (Tukwila) series was released in early 2010. The top model, the 9350 has: 4 cores @ 1.73/1.86 GHz (unimpressive freq, but can execute up to 6 instructions/clock vs 2-3 for Core) 24 MB on die L3 cache 2-way HyperThreading (8 threads per chip) 2 DDR3 memory controllers 34 GB/s QuickPath Interconnect 96 GB/s aggregate It's a very modern chip with serious performance, especially on floating point workloads, as has always been the case with Itanium.
