Itanium also does dynamic scheduling. It's not really VLIW - it is just optimized to decode and schedule a lot of instructions at once.

- FullyFunctional 4y agoThat’s not what dynamic scheduling means. What you need is to dynamically extract ILP so you can get good performance on single thread applications in light of branch mispredictions and cache misses. We are talking SPECint, not SPECfp nor throughput (threading). x86 chips and Apple Silicon show what you can do here and to do that with IA-64 would have been harder, not easier.
