Thais page describes the differences between the ZyXEL VMG1312-B10D and the ZyXEL VMG3925-B10B routers.
==The main differences are
*VMG3925 is more expensive
*VMG3925 has 2.4 and 5G WiFi radio, the VMG1312 has only 2.4G
In terms of hardware differences between the router:
The main difference, is the addition of an additional
radio alongside the existing 2.
customers in areas where the 2.
It does however help in cases where the 2.
It's believed that the VMG3925 has an extra common-mode noise filter on the telephone line.

You may note that the VMG3925-B10B has a slower CPU, however it also contains more dedicated hardware for packet processing compared to the VMG1312-B10D which needed the extra CPU clock cycles to deal with processing packets.
The VMG3925-B10B's SoC contains 1 Gigabit PHY, which connects to the Switch chip for the WAN and LAN ports. Radios are connected to the SoC, so packets passing through WAN/LAN<>WLAN would be limited to the bandwidth of the single Gigabit PHY inside assuming no other limiting factors
