⚠ AMD reset bug
RDNA3 (Navi-class) iGPU is subject to the AMD reset bug; Proxmox wiki: AMD Navi 5xxx/6xxx suffer the reset bug and need extra effort, may not be fully stable. vendor-reset may or may not cover newer APUs.

Cited public information, not purchasing advice. Onboard NIC silicon and BIOS can differ between production batches of the same model name — confirm the revision you receive (
lspci -nn) before relying on a NIC or passthrough claim. Idle draw depends on OS, mains voltage (120 V vs 240 V) and power tuning (powertop).
