MIPSBE vs 4xARM, which is more productive?

Question

network hardware

There are two Mikrotik routers: hAP ac and hAP ac^2 .
If you believe the specifications, then in addition to the obvious difference in antennas and the sfp port, their brains differ in processor: 1 MIPSBE core versus 4 ARM cores.
Which of these routers will be more productive as the main router holding 2 VPN connections, and which should be left as WDS Station?
// due to the price difference by 2 times, doubts creep in that one MIPSBE core can be much more powerful than ARM's cores

Answer 1

On your links, open the tests tab and notice that hap ac2 is more productive, and also supports khaidvarno encryption
