Not an eli5 because I'm still not caught up on it but if my memory serves, RISC-V is an open source architecture for processors, basically like amd64 or arm64, actually I'm pretty sure ARM's chips are RISC derivatives.
Edit: correcting my comment, ARM makes RISC chips, not RISC-V
ARM and RISC-V are entirely different in that neither one is based on the other, but what they have in common is that they're both RISC (Reduced Instruction Set Computing) architectures. RISC is what makes ARM CPUs (in your phone, etc) so efficient and hopefully RISC-V will get there too.
x86 by comparison is Complex Instruction Set Computing, which allows for more performance in some cases, but isn't as efficient.
So is Reduced Instruction Set like in the old assembly days where you couldn't do multiplication, as there wasn't a command for it, so you had to do multiple loops of addition?
Nah, the Complex instructions are ridiculously complex and the Reduced ones can still do a lot of stuff.
