Although IA-64 (Itanium) has been discontinued, it did have some innovative features that were ahead of its time. Here are a few examples:

1. **Explicit Parallelism Instruction Computing (EPIC)**: IA-64 was designed to exploit parallelism in programs explicitly, which allowed for better performance on multi-threaded workloads. EPIC introduced a novel instruction format that included explicit parallelism information, enabling the compiler and hardware to optimize parallel execution.
2. **Predicated Execution**: IA-64 introduced predicated execution, where instructions could be executed conditionally based on a predicate (a boolean value). This allowed for more efficient execution of conditional code paths and reduced branch misprediction penalties.
3. **Speculative Execution**: The architecture supported speculative execution, which enabled the processor to execute instructions before their dependencies were resolved. This improved performance by reducing stalls and improving instruction-level parallelism.
4. **Register Stack Architecture**: IA-64 used a register stack architecture, where registers were organized as a stack. This allowed for efficient allocation and deallocation of registers, reducing overhead and improving performance.
5. **VLIW (Very Long Instruction Word)**: IA-64 instructions were designed to be very long (up to 128 bits), allowing for more instructions to be packed into a single instruction word. This improved instruction-level parallelism and reduced instruction fetch bandwidth requirements.

Other architectures have borrowed or been inspired by these innovative features:

1. **x86-64**: The x86-64 architecture, used in modern Intel and AMD processors, has incorporated some of the EPIC concepts, such as explicit parallelism and predicated execution.
2. **ARMv8-A**: The ARMv8-A architecture, used in modern ARM processors, has adopted a similar register stack architecture to IA-64.
3. **RISC-V**: RISC-V, an open-source instruction set architecture (ISA), has incorporated some of the EPIC concepts, such as explicit parallelism and predicated execution.
4. **IBM POWER**: The IBM POWER architecture has also borrowed some ideas from IA-64, including the use of a register stack architecture.

While IA-64 ultimately failed to gain significant market traction, its innovative features have had a lasting impact on the development of subsequent architectures.
