    ARM chips aren’t better at power efficiency compared to x84 above 10 or 15W or so. Apple is getting a lot out of them because TSMC 3nm; even the upcoming AMD 9000 series will only be on TSMC 4nm.

    ARM is great for having more than one competent company in the market, though.

      Do you have a source for that? It seems a bit hard to believe.

        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.
