Because you can buy an M1 Mac today.
By the time this Ryzen CPU appears in a real PC you can buy, the next-gen Apple Silicon Macs will have arrived, and they will be several years ahead of this Ryzen.

You can order one today. I'm still waiting for mine I ordered in March.
For disk, I just put a 1tb NVMe in an external USBC enclosure, cuz most of my data doesn’t need crazy I/O and I feel like Apple charges too much for disk space.
Memory management is quite usual, nothing magical. The disk is faster, but it's not the reason to rely on swapping, still.
