47 bytes per nanosecond? That's 47 GB/s. My machine couldn't stream data into the CPU that fast. Though if you're exclusively operating within cache then I suppose that's possible.

Honestly, I've never really understood why people care so much about portable binaries unless they're running their OS off a thumb drive on multiple different computers. My computer doesn't change instruction sets. And if I did put a new CPU in my computer, I'd want to get new binaries compiled for a more powerful instruction set.
