Honestly Arm and Risc-V are under rated. Not all are libre compatible but there are a few that work well with exclusively free software and have much less power draw.
All even half-way relevant architectures but x86 and z/Architecture are RISC nowadays: ARM, Power, MIPS (The Chinese tried to revitalise it but they seem to be switching to RISC-V), Atmel AVR. Oh speaking of microcontrollers: Z80 (CISC) still lives though arguably it’s genetically an x86. And then of course RISC-V which most of all is an open standard, and a clean slate. Also, the first vector insn set that also runs on hardware that isn’t a supercomputer.
I’m pretty sure they meant the open source RISC-V, not any reduced instruction set ISA in general.
If you want to talk about underrated look into POWER CPUs.
Motherboards like the tallos 2 are completely open source( except for an nvme storage controller) and they already offer x86_64 levels of performance. The only con right now is software support and the cost.
There’s like 2 arm laptops out there and like 0 risc-v though, that’s why they’re underrated lol
Not only will ARM and Risc-V likely not save Linux it will most likely harm it. I doubt there will be many Linux computers running Arm and Risc-V and the few computers that use those architectures won’t run Linux well. M series Apple computers only run with reverse engineering and even then many basic features don’t work.
Maybe I’m missing something, how will arm kill Linux? We already have good arm support.
Most software doesn’t work on arm and despite many distros supporting arm there aren’t many arm computer manufacturers supporting Linux. There is a small possibility that Qualcomm could announce that their desktop CPUs support Linux but I’m not so sure.
