Turris Omnia or alternative?

What I am getting at? I thought that was pretty clear, putting arm efficiency cores into a router is a bad idea if you want to actually do interesting network things via software. And for a 700$ device this IMHO is not a balanced choice.
At that price point picking a SoC with better CPU cores would not have affected the final price all that much.

Moving to ARMv8/ 64 bit is nice (for many reasons, better upstream support/ attention (many upstream projects are actively killing off their 32 bit ARM support already), slightly more standardized boot process (pscd/ kvm capable), no issues with 32 bit time/ y2k38, …), but in terms of attainable performance, cortex a53 is at best roughly on-par with cortex a15.

So the omnia's dual core a9 seems to perform more consistently than many quad core a53s.... IMHO the a53 is decent for what it is, but that is not a powerful CPU....
Arm marketed the a53 as delivering the a15/a9's performance at a lower power consumption, but failed to mention that this only holds for selected conditions.
And since arm's 32 architecture was less hobbled with old legacy cruft than x86's, going from 32 to 64 bit for arm by itself is not a big and conclusive win.
However, my desire is not for the ten64 to have used old 32bit cores, but simply modern 64bit cores from arm's performance line, like e.g. a76.

Well that's funny, I asked almost the exact same question on Turris' side!

I'd be quite happy with another Omnia, personnally, but I can't find any out there... I don't need that much RAM or anything, "just" gigabit routing and possibly an SFP port.

I recommend opening a new topic with your requirements.

I figured "but this thread is exactly my requirements!" but then someone else pointed out the original post might be a case of a XY problem and, since you asked, I just made a new post:

Thanks!

You seem to miss the point about how the hardware is designed to be utilized?

Could be, however equipping a $700 router with sub-optimal CPU cores is not a sign of competent design in my book. Not a problem, they are clearly not seeking (or getting) my business...
Let's talk shop here, the a53 is a design from 2012 never aimed at high performance, putting this into a relatively pricy router a decade later is not aiming for adequate CPU performance... this is fine, if you trust the accelerators, by all means go for it, but please do not argue that a53's are suitable CPUs for anything not aiming for really low power in 2023.

You don't seem to understand what the DPAA2 is about, that's what does the heavy lifting and keeping the power usage down.

Dizzy, why continue discussing this when:
a) you are clearly not listening to what I say
b) there are multiple valid positions reasonable people can take, including yours and mine?

My point is still using a53s in 2023 is not a good choice for anything CPU heavy, if you can and want offload all your processing that can be acceptable.

I'll chime in to say that I've had great results with this x86 box, the Qotom Q750G5: https://www.amazon.com/Qotom-Q750G5-S05-Gigabit-Fanless-Firewall/dp/B0B54J3X49/

With a Gemini Lake J4105 quad-core CPU (no hyperthreading), it's really fast, enough to run CAKE at full 2+Gbps rates to my local test server.

At <$150 for a 4GB RAM + 128GB SSD, it's a no-brainer for an OpenWRT router for fast lines.
That + a set of Omada managed access points and one has a setup that slays the >$500 mesh systems for less than $500.

Remember to boot into the BIOS and set the power recovery setting to 'last state' so it restarts after an outage. While all routers/modems should be on a UPS regardless, batteries are finite, and a UPS will shut off.

You're again completely missing the point about the hardware and in that case anything below server class CPUs are useless by your reasoning.

Respectfully, maybe, because you are not making an elaborate point beyond "but DPAA2"?
I am fine with disagreeing with you here, and I accept that my position is not any better or worse than yours, but I am a bit puzzled why you seem to believe that you can convince anybody of anything without actually bringing elaborate arguments?

No, that is not my point. My point is that for a $700 performance router I would expect better CPUs than 2012's underwhelming Arm a53s. Neither a72 nor a76 (which I gave as an example) are exactly "server-class" (as in big iron server)... if we would be talking a typical < $100 all in one router I would be less pointed about that, but for $700 replacing the CPU would have either been inside the existing budget or the required price increase would have been IMHO insignificant.

Again, reasonable people might disagree, this is primarily my subjective take and not anything approaching "ground truth".

Seems they don't ship to EU/Germany :confused: - Generally a very solid piece of hardware imo but no SFP and no WIFI.

Good find! Sadly not <$150 but rather 316 EUR for 4 GB RAM + 128GB SSD but I must admit, that I haven't yet figured out how to scroll through their products is there a special trick? If I click products, whichever (I tried all), category I click it always yields "no results"

isn't this omnia prince range?
I don't think you'll hit the below 150$ mark with new items (with SFP) but ebay is a great place for used x86/64 appliances so you have a good chance of finding it there - maybe edit the thread name and 1st post to express your needs in more details.

LE - cheapest I could find is ~210eur shipped https://www.aliexpress.com/item/1005006232791210.html

Aah, I got it I think: https://www.qotom.net/product -> MiniPC series -> Sfp yields Mini PC Q20331G9 S10 which is the one you linked. So this one on their main page: https://www.qotom.net/product/RouterPC_Q20331G9S10.html

And it of course is more expensive, because it has more ports compared to the one suggested by @JonFo (Qotom Q750G5).

So it seems to have 5x Intel Ethernet Controller I226-V (https://www.intel.com/content/www/us/en/products/sku/210599/intel-ethernet-controller-i226v/specifications.html) along with 4x SFP.

With my limited understanding I currently assume, that the 5x I226-V would be the eth ports I connect my devices to - then I have 4 SFP ports of which I would only use one (to connect the fibre cable from my ISP)?

EDIT: As far as I understood https://community.fs.com/article/sfp-module-what-is-it-and-how-to-choose-it.html - SFP is a kind of module slot to connect copper/fibre connectors to - So this would require, that corresponding drivers exist for it in openwrt, am I understanding this correctly? (Apparently Id need a fibre module, like this one: https://www.fs.com/de/products/75336.html)

Next It would interest me very much if I could make use of the remaining SFP slots, as Qotom doesnt seem to offer a device with only one SFP slot.

SFP doesn't need a driver as it's a piece of dumb hardware like ethernet ports.
But SFP modules (the one you connect your ISP fiber into) need drivers and yes, you could make use of the remaining SFP ports with SFP-to-ethernet modules (more expensive then buying dedicated switch) needing supported drivers as well

I own an omnia, and have used openwrt since the wrt54g days. I would recommend something else simply because it’s so damn expensive for what you get. Considering you can get a mikrotik hex or hap for like 50usd the omnia is way too much for a gigabit router in my opinion.

I can buy like 4 mikrotik hex s for the price of on a turris, and they are probably just as fast.

The omnia is going to beat them if you need to run packages that take up more memory though, but for the price you can go x86 which is just easier overall to manage.
