That's actually expected once you think about it, it's a natural consequence of prefetching.

Heh. That line often gets called out.
Lots of things are expected when you deeply understand a complex system and think about it. But, like, not everyone knows the system that deeply nor have they thought about it!
If that wasn't the case the machine would have to prefetch to register file. I don't know of any CPU that does that.
