The X670E AORUS MASTER holds fast to the core of X670E's feature set, without quite extending to the capabilities of the X670E AORUS XTREME. WiFi 6E, Dual PCIe 5.0 NVMe M.2 slots, a single PCIe 5.0 x16 slot, one USB 3.2 Gen2x2 port offering bandwidth of up to 20Gbps, 16+2+2 phase power and a supporting round of PCIe 4.0 expansion slots and M.2 storage are all excellent building blocks, but they won't be uncommon amongst the board's competitors. This is where proprietary features come in.
