I don't know if AMD allows more or fewer _situations_, but empirically, I'm seeing a lot of total cycles lost to this on Zen 2 and 3, and much less on the Intel CPUs I've been testing (mostly Skylake derivatives and Alder Lake).
I haven't tested Zen 4 or 5, but I haven't heard anything that indicates they should be a lot better.
