I don't believe there is any official documentation on this, but https://github.com/JuliaLang/julia/pull/49430 https://github.com/JuliaLang/julia/pull/49430 for example added prefetching to the marking phase of a GC which saw speedups on x86, but not on M1.
It should be pretty easy to find a MWE that shows the behavior. Something like summing an array of int* should do it.
