What is the maximum throughput between two ports on Mikrotik 750Gr3?

Question

Mikrotik

So there is a Mikrotik RB750Gr3 router. The block diagram looks like this https://i.mt.lv/routerboard/files/RB750Gr3-dsw-161...
From this it follows that 5 ports of the router are each connected to their own "line". Let's take ports eth4 and eth5. They are connected to 2 different lines. Each line is signed as 1gb/s. Is it duplex speed? That is, if traffic goes from eth4 to eth5 and vice versa, then both data streams will have a speed of 1 gb / s (routing, traffic in both directions goes simultaneously)?

Answer 1

on this diagram, the operating mode is with a disabled switch (when there are no ports with a master-port). in this mode, ports 1, 3, 5 are connected by one 1Gbps link to the processor, the second link goes to ports 2 and 4. respectively, between ports 1/3/5 and 2/4 you will not have more gigabit, for example, traffic from 1 goes to 2, from 3 to 4, in total it will run into gigabit and will be ~ 500 Mbit for all. Naturally 1Gbit full duplex, both reception and transmission will be 1Gbit at the same time.
