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 was believed that the VMG3925 has an extra common-mode noise filter on the telephone line, but this is not the case.
▲5GHz does NOT have a "longer reach" than 2.4GHz, so it will not help in cases of signal attenuation.
▲It does however help in cases where the 2.4GHz band has too many other devices on it.
This router also has a dedicated WAN port, for FTTP. No configuration is
router, it has 1GBit/sec LAN ports. This may be beneficial for FTTP
customers as to not have the LAN ports becoming a bottleneck.

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
