Qemu is only able to achieve native performance when running in conjunction with a hypervisor like KVM. Hypervisors don't do binary translation, so the guest architecture needs to match the host architecture. Running x86_64 qemu under rosetta would likely be much slower than running aarch64 qemu, because it would be running an emulator inside of an emulator.
