ASRock X570 Phantom Gaming-ITX/TB3 (AM4/AMD X570/Mini-ITX/10-Phase VRM/Built-In Thunderbolt 3) Review
The X570 Phantom Gaming-ITX/TB3 is a legacy AM4 Mini-ITX board still sold for Ryzen 2000/3000/5000-series builds, notable for including a built-in Thunderbolt 3 port, a rare feature on AM4 ITX boards that remains useful for eGPU and high-speed external storage setups.
A 10-phase design using 60A power chokes and Dr.MOS components gives this board reasonable headroom for Ryzen 5000-series chips like the 5800X3D once BIOS updates added support, though buyers should confirm current BIOS revision before pairing with newer Ryzen 5000 CPUs. Two DDR4 DIMM slots support up to 64GB total capacity, with overclocked speeds of DDR4-4533 and above achievable depending on the memory kit. A single PCIe 4.0 x16 slot handles the GPU, while storage is limited to just one M.2 slot (PCIe 4.0 x4, "Hyper M.2") plus four SATA III ports with RAID 0/1/10 support, a notable limitation compared to newer AM5 ITX boards in this batch. A 1GbE Intel I211AT controller handles wired networking, paired with Wi-Fi 6 (802.11ax) and Bluetooth 5.0. Audio uses a Realtek ALC1220 codec, and the built-in Thunderbolt 3 port (40Gbps) remains this board's standout feature years after its original release. Against the Gigabyte B550I AORUS Pro AX in this catalog, the X570 Phantom Gaming-ITX/TB3 offers PCIe 4.0 GPU bandwidth and built-in Thunderbolt 3, at the cost of only having a single M.2 slot versus the AORUS Pro AX's two.
