If you look at pfsense/OPNsense hardware recommendations, it’s almost all using chips like the Intel N5105 (10W TDP, though admittedly “TDP” is itself a messy term) or J4125 (also 10W TDP). Using ARM hardware is asked a lot in the community forums, and it’s one of those questions that will get you a flamed for not checking Google first. The power usage benefits for switching to ARM just aren’t there.
There is the Netgate 1100, which runs ARM on a proprietary build of pfsense. The community has largely ignored it in favor of Intel chips. There isn’t much of a price advantage, and the performance is lackluster.
That said, there’s lots that you can do with a sub-10W chip, and x86 has nothing modern there.
Personally, I cobbled together an OPNsense firewall out of some old desktop parts I had on hand. Power usage is a bit higher, but not so much that I care. I would like a more viable high-end ARM option, though, just because I don’t want x86 to be the only option.
Extrapolating the specific use case of pfsense routers to all other applications seems misleading, especially when arm laptops and servers exist that prove their utility and power savings for their use cases. It seems to be the case that there isn’t a particular arm device that is priced well and well suited for pfsense, which does have somewhat unusual requirements compared to other applications.
