and hey its a netgate box vs a china box

Exactly where do you think the Netgate device is manufactured?

@jwj

As was the Unifi AP I recently bought. Does the Netgate have those AES-NI instructions?

AES-NI is an Intel extension

@jknott No. It doesn't. The i5 will crush the ARM device for single thread performance and OpenVPN throughput. Question is, do you need that performance? Netgate box will be more energy efficient.

For what it's worth, I've always seen the 5100 as entry level. Then I cried inside at the price... The LAN<->LAN filtering rates is what I pay attention to. I would want line speed.

It's on other CPUs too.

Please mention just one ARM CPU that has it (AES-NI)

The Netgate takes a 12V 2A power supply, which means it runs less than 24W. The Qotom takes 15W, so there's not much difference. As for the AES-NI instructions, it wasn't that long ago that plans were dropped to require them. I don't have much of a need for those, as I only occasionally use the VPN, but I wouldn't want to lose the ability to update the software for the lack of them.

According to that article I linked to, several do.

@jknott For sure not an obvious choice. You're going to have to have a think about it.

Also some of the discusion around pfSense+ leads me to believe the REST API is on the roadmap. Will that bring back the AES requirement or will they work around that with the other instructioin sets available on the ARM devices. I have no idea...

What do you see as the lifespan of this device?

@jwj
couldn't agree more here with @jwj

Where does it say that an ARM CPU has AES-NI ??

I see this , where it specifically mentions that AES-NI is Intel/AMD only

Other architectures have Crypto instructions too , but not AES-NI

Well, based on my other experience, until something significantly better comes along or it dies (as happened with my previous firewall). I'm not one to run out and buy the latest & greatest, unless it yields significant improvement. For example, if a pfsense update had required AES-NI, then I would have bought something that supports it, as the HP computer I was running didn't.

Another example, my current desktop computer case originally had a 32 bit CPU. I've since replaced the mom board a couple of times. The case is so old it's cream coloured, not black (matches my IBM model M keyboard, but not much else). I also recently finally got an AP that support 5 GHz.

BTW, that keyboard is built like a tank and old enough to not have a Windows key.

The CPU TDP is 15W

The NIC's (Phy's) + other electronics also consumes

My Qotom came w. a 12V/5A PSU

So, what does pfsense do with those Crypto instructions? Ignore them? I could be wrong, but I would assume software written for an ARM CPU would take advantage of the ARM instructions.

It's been a while since I've written software, but I seem to recall compilers can link in appropriate libraries for the different target hardware.

There are some threads concerning that. To the best of knowledge it does ignore them at the moment.

I have sent you a private message...

If Netgate want their ARM boxes to perform decent w. crypto they probably have enabled the usage of any Crypto instructions available.

I could be wrong, but I would assume software written for an ARM CPU would take advantage of the ARM instructions.

On embedded programming you often have to make sure to use the correct libraries. It's usually done with a couple of compiler switches , that pulls in the correct linker library. Sometimes you even have to set a few bits in the MCU , in order to enable any "Crypto part in the MCU" , often "extensions" are disabled on POR , to minimize power usage.

Yepp , if being told to do so.

But you were referring to AES-NI
And i replied correctly it was an Intel extension.

I'm very much the same. For example, my 2015 VW Golf is just about broken in. I'll drive it until it has no value and then replace it.

Buy nice things and use them, don't worry about the new things until your done with the ones you have ;)

How much does it actually consume? What does the label by the power connector say? The info I saw listed 12V 2A. It's good practice to over spec things like power supplies, provided you don't go overboard. Either way, both devices are in the same ballpark and will require far less power than the HP desktop computer that's being replaced.

I haven't measured it yet , i might

I would expect the 2100 to use less than the Qotom.
Guesstimate ... Around half.

and will require far less power than the HP desktop computer that's being replaced.

I totally agree

My original intent was to write AES-NI or equivalent, but I didn't bother.
