This motherboard will be available in two variants (with onboard WiFi AC and without it). Let's start with changes from X370. Apart from the design makeover and much fancier shrouds, the X470 version has actual heatsinks over VRM. The current is delivered through two 8-pin EPS connectors (the X370 only had one). The X470 Carbon Pro AC lost one PCIe x1 slot, but it gained two additional SATA ports (in total there are 8).
