How is RISC-V better than x64? Aren't both of them just ISAs? The only pro I can find is that RISC V is cleaner (less legacy). But no one programs in assembly these days so why is this an issue?
- rwmj 6y agoIt's more about the licensing of the ISA. Try creating your own compatible x86 processors, and find out how long it takes before Intel's attack lawyers come down on you. ARM is a bit better but you still have to pay licensing fees. For people who want to git clone a design and manufacture it without involving lawyers or licensing fees, RISC-V is likely the best choice.
- Pet_Ant 6y agoThink of it as MP3 vs Ogg Vorbis. It's equivalent, slightly newer and a bit nicer, but really the benefit is that it's patent-unencumbered and you are free to tinker with the ISA and build your own versions at will.
- loudmax 6y agoNot many people program in assembly, but teams working on compilers like gcc and LLVM very much do care about the ISA. Apple has been able to make great progress moving from Intel x86 to their own custom ARM M1 processor. The way I understand it, RISC-V may allow similar advances.
