I have the RB750Gr3 with 3 WAN in and several mangle rules to route traffic specifically to one or the other based on the device. worked great.
I have to rebuild a similar setup, what's a good upgrade from the RB750Gr3? can the RB5009UG+S+IN be considered as more powerful version?
PS: I only want the router part, not the wifi.

RB5009UG would be a massive improvement over the Hex assuming the same network characteristics (bandwidth, clients, etc). You won't regret it. That said, do you need that kind of firepower at the cost of $$ or could something more modest in capabilities and price serve you? Maybe tell us more about your use case if you want to really take a look at things. If cost isn't a deterrent and you just want something that will work and work well, RB5009 it is all day long.

Might regret the 5009 if they run into the issues with throughput the devices has (see viewtopic.php?t=182691 for example).

Not everyone seems to experience that so I'm not convinced it isn't a config issue. Regardless, if he's happy with a hex now, he's not going to have issues with the rb5009.

MrYan, that thread related to problems for some users achieving only 1Gb/s where they expected 2.5Gb/s, which is not available in the RB750Gr3 nor requested by philip2284. Even if that ticket were a real problem, the RB5009 still has the RB750 for breakfast, albeit more expensively.

Thank you all. How would I check my current setup usage rate?

You can see ram used, cpu use, disk used/free space (and other stuff)

Another couple of cheaper (but less good) router options are:
(Note: You can disable, and with current V7 actually remove the wifi/wireless packages)

Hap AC2,
- CPU quite a bit faster than hex
- Only 128M Ram (vs 256M for Hex)
- Similar amount of flash to hex, is restrictive when wireless/wifi required, ok when not, and
the corresponding package is removed.
- Similar form factor to Hex
- No VLan filter hardware Offload, (But switch chip is quite powerful in other respects)


Hap AX2
- Better switch chip eventually (Maybe, Work in progress)
- Fast CPU
- Plenty of Ram, Flash
- Similar form factor to Hex
- No USB Port

Thank you for the comparisons.. I have issues that I am wondering if they are related to the RB750Gr3's CPU and I do have a hAP AC2 I could potentially swap it with.. I didn't realize/notice that it has a faster CPU.

I didn't realize/notice that it has a faster CPU.

It's hard to say which CPU is faster simply from the part number. But all MT products have published test results and that somehow relates to CPU performance.

hEX - RB750Gr3
hAP ac²

The tests with less processing (e.g. no firewall filters, large packets) will usually saturate interfaces to line rate, but most complex tests (e.g. 25 filter rules, 512 byte packets) will indicate real-life performance and tgere CPU performance will make a difference. Also observe number of wired ports, devices with smaller number of ports (e.g. cAP ac) will tend to be port-throughput limited in test results, not by CPU performance.

Note that tests are synthetic ones (so they are repeatable) and hence per-se don't represent capacity, but tbey can be used as indication and to compare apples to apples.

25 rules / 512 bytes is the number I check when comparing the real life performance of mikrotik routers.

Introducing the "inverse bang for the buck" unit of measure :
RB750GR3=60$=385 Mbps (25 routing rules@512B)->155$/GBps
Ax2=99$=913 Mbps (25 routing rules@512B)->108$/GBps
AC2=79$=986 Mbps (25 routing rules@512B)->80$/GBps
RB5009=219$=3096 Mbps (25 routing rules@512B)->71$/GBps

In a nutshell, get an AC2 if you have a less than 1GB ISP connection, even if it has a tiny amount of storage, since you won't be using the Wi-Fi it should be good enough.
If you have a 1GB or faster connection, go for the RB5009.
The Ax2 would however make sense if you think you may re-use it in the future for its Wi-Fi capabilities, and 128 Mb storage is enough, the only issue (or non-issue) is IMHO the lack of a USB port.

Note that philip8224 never mentioned "it should cost as little as possible"...
Some people are always on a tight budget, for others spending 50-100 on a better product is not as much of an issue.

At any rate DO NOT BUY A hAP ac2 !!!
Maybe ax2 or ax3 could be considered, but MikroTik should not make any profit on selling hAP ac2's...
I would recommend the RB5009.

Sure , it is just another way to look at things, tuppence is tuppence, Fiddlesticks, boy! Feed the birds and what have you got? Fat birds!

Ax3=139$=1145 Mbps (25 routing rules@512B)->121$/GBps

Indeed. But a buck saved on previous project is a buck of budget increase for next project. Which is usually even more important when there's involvement of a financial controller in shape of better half

Well, at work I just bought 3 new RB5009UPr+S+IN and as they provide PoE they can supply the access points at the locations and make replacing the PoE switches less expensive (we had PoE everywhere for VoIP phones, but fixed telephony has been phased out so now only access points require PoE).
The powersupply included with the PoE model also seems to be better quality.

One of them will replace a RB750Gr3 which has been serving for over 7 years. At that time I become a little nervous about the powersupplies...

Also, the RB5009 has ample memory (both flash and RAM) for future expansion of RouterOS and running specialized containers.

At any rate DO NOT BUY A hAP ac2 !!!

*shrugs* I already have one at a site, I can swap it for my RB750Gr3, just needing to transfer the configuration.

Don't buy because it is previous generation now? Or is there some other major defect with it?

There is a major problem: it has only 15.3 MB flash (several other devices have 16 MB but this has less) and this is becoming a problem with recent RouterOS versions.
You can install 7.12.1 and keep that as long as possible, and maybe there will be a solution (like a lite version of RouterOS).
Until then, it is just a ticking timebomb.

Only config you could try: remove the wireless package so you have only the routeros package on it.
That frees some space and may make it reliable, but at every update there of course remains the risk that it is somehow automatically re-installed as part of attempts to solve this problem. So do not update remotely when you cannot go to the site to netinstall.
