Regular Ryzen parts are still reasonably relevant for server use! They support ECC, so there's nothing immediately disqualifying them - see the rebranded "EPYC" 4005 series, for example.

A company like Hetzner isn't going to care an awful lot whether they deploy one big SP5 server or four small AM5 ones for the VM instances they rent out: the only thing that matters is TCO per performance.

Want to stick four NVMe SSDs, a 25Gbit NIC, 256GB of ECC RAM, and some OOB module on a Ryzen board? No problem whatsoever. Want to do the same with an Apple CPU? Ehhh, that's going to be slightly more challenging...
