It has four radios (that means four chips, with their amp/filter ciruits), Broadcom's fastest CPU, twice the usual amount of RAM, and is marketed as an ROG device so it comes with a premium added on top of the regular price, plus it's the flagship which adds another premium.Can someone explain to me why this router costs $700? I was thinking about finally updating my 87u with a new asus router but $700 seems crazy high to me for a router.
Also extra costs for providing two 10 Gbps ports. Look around for the typical cost for any router with one or two 10 Gbps ports. None of them are cheap...
All of this adds up.
Since you were on an RT-AC87U so far, I doubt you need any of these extra features.
