I think you can but you basically need to learn about a super simple and well characterised processor like the 8080 and write assembly for it. On x86/AMD64 there's no hope because they're out of order and have opaque instruction decoding. They could be doing anything! Performance and knowing what you're doing are sort of at odds with each other in that respect.

> "out of order"

Those who bring up OoO as if it caused unpredictable execution should ask their LLM what a reorder buffer is and why it exists.
