If you’re concerned about power draw, then fair enough. The AMD Rome/Milan based chips are very thirsty. Although they can all be set with a fixed cTDP value in watts which they stick to rigidly...
Consumer Ryzen entails a compromise with multiple devices, including any Thunderbolt controllers, secondary M.2 slot, USB controllers etc all hanging off the chipset which is connected to the CPU with a grand total of 4x Gen4 lanes in the case of X570. It all has to flow through this narrow pipe.
But it seems like you’re sure that your use case won’t be hobbled much by this, and single-core boost performance on the consumer Ryzens is appreciably higher.
A mitigating method is using an X570 motherboard that allows bifurcating the Gen4 16-lane GPU slot into 2x Gen4 8-lane slots, such as the ASUS WS X570 Ace. This particular board also uniquely exposes a third full bandwidth 8-lane Gen3 slot connected via the chipset’s 4-lane Gen4 link.
I’ve built several media servers using this board with a GPU, 8-channel capture card, a 25Gb NIC and a Gen4 NVME drive all running on a single consumer Ryzen platform with nothing oversubscribed.
