ASRock X570 Phantom Gaming-ITX/TB3 vs Gigabyte B850I AORUS PRO: which one fits your build
The ASRock X570 Phantom Gaming-ITX/TB3 suits budget Ryzen 5000-series SFF builds using existing AM4 CPUs, though it is not built for anyone needing more than one M.2 slot for storage. It is equally the pick for AM4 builders who specifically need built-in Thunderbolt 3 for eGPU or fast external storage. It is not the one for new builds where AM5 offers a longer upgrade runway for similar money. The Gigabyte B850I AORUS PRO is the one to take for builders who value screwless installation in cramped SFF cases, though it is the wrong buy for extreme overclockers needing more than mainstream-tier VRM headroom. The same goes for Ryzen X3D builders who want X3D Turbo Mode tuning on a clearly specced ITX board. Avoid it for buyers who want three M.2 slots like the B650I AORUS Ultra offers.
