RB750gr3 vs RB760IGS?

RouterOS Beginner Basics

Hi.

A couple of days ago I saw a YT video which recomended some routers for administration according to the size of the network and the traffic to handle, as follows.

RB750gr3 up to 250 hosts and 100 Mbps
RB760igs up to 500 hosts and 200 Mbps
RB4011 up to 1000 hosts and 500 Mbps
CCR Series 1000+ hosts and 500+ Mbps

However, when I compared specs at mikrotik website I found that RB750gr3 and RB760IGS are almost the same hardware excepting the sfp port at RB760IGS.
Both have the same cpu runnign at same frequency (MT7621A @ 800MHz), and the same core/thread count (2c/4t).
Both have the same amount of ram and internal storage: 256MB Ram and 16MB storage.
Both have the same amount of gigabit ports: 5
Both have the same numbers at test results, ethernet test results and IPsec test results are identical.
The only difference I saw is RB760IGS have a SFP port while RB750gr3 doesn’t.
Inlcuding the block diagrams with disabled switching or enabled switching are pretty the same, except SFP port at RB760IGS is connected through XOR gate on first cpu line between cpu and ethernet ports.
If these routers are practically the same equipment, then… how they can suggest RB760IGS to handle a network twice the size of the first one.
Am I right? or I am missing something?
Thanks in advaced.-

Is MikroTik a good start for a complete noob?

As you deducted yourself, any suggestions of particular router models for particular use cases is highly subjective and one has to verify how tgey compare to facts.

BTW, number of clients/hosts doesn’t have much to do with router performance.

Which would be the parameters to have in mind besides traffic?
According with test results, I guess those would be… number of firewall rules, queues, packet size, amount of vpn tunnels, but no more come to my mind.
May you tell more about it? Thanks.-

What is the throughput of your WAN connection,
and what will the users be doing besides how many

The estimates in the video seem rather arbitrary to me. The fact that the test results for both devices are the same tells you everything you need to know - they are comparable from a performance perspective. But the fact that the RB760IGS has the SFP port, as well as POE out, is a distinctive difference from the hEX and may be worth the modest additional cost to you.
