That's not true. I'm using it on a Ryzen 5950X and it's of tremendous help.
https://github.com/rr-debugger/rr/wiki/Zen for details on running it on AMD Zen. Personally, I'm using the kernel module.

As the commenter above says, it works on Zen. There is also experimental Aarch64 support (for userland that uses CAS instead of LDREX/STREX).
