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...

1. 9950X isn't on the chart.

The 9950X3D2 was already tested. And was included as comparison point with the fastest possible version of its predecessor (Zen 5).

Some evidence that contextless numbers are meaningless is that your source, David Huang, does include the 9950X but in his results it scores much higher than everything on C&C's chart too (7.25/11.4)
