Asus RT-AX86U vs RT-AC86U - Battle of the Best AC WiFi 5 & AX WiFi 6 Router - Worth the Upgrade?

It is known that the dual core of the AC86U when doing large file transfer over USB 3 maintain the speed and connection rates can start to "max" the router out under heavy loads with file transfers due to older dual CPU

They're more or less the same CPU, both are A53 Cortex cores, the only difference is in the number of cores - which has no impact on transfer performance.

No but if your also having major networking traffic and doing file transfers, i'd say that will start to effect things with both CPU's pegged

LAN transfers are handled by the network switch, and therefore do not use any CPU time (or barely any).

SMB transfer from a shared USB Disk would, but it's also single-threaded so it doesn't benefit much from having more cores (you still have one core free for NAT or routing).
