  and, honestly, RISC-V is the right place to spend it. RISC has super powers.

    What do you mean by that. RISC-V is open source but it doesn’t have “superpowers” that I know of?

      “reduced” is the super power. I would much rather put the smarts into the assembler/compiler/interpreter than the silicon. have been followed RISC since the 80’s and discovered that I am really a RISC guy living in CISC world. open arch is the world dominating cherry-on-top.

        That’s not really true. Yes avoiding complex instructions makes the front end easier to pipeline but there are lots of smarts in the backend to do prediction and scheduling to keep the execution units fed. The ISA might be free to use but no one is sharing their highly optimised server silicon architecture designs.

        RISC-V’s challenge is can they standardise the software ecosystem enough that things just work across a multitude of chip providers or does everything devolve into specialist distributions taking advantage of each manufacturers “special sauce” custom instructions.

        Gaining design wins over Arm’s microcontrollers for bespoke hardware was the easy bit. Replacing stuff in the server space is much harder and something that took Arm decades to make inroads into.

        Do you have any resources by any chance that explain the difference well?

        I’ve coded in assembly and understand instruction sets at a very rough level, but I’m not really familiar with specifically what differentiates RISC / ARM / x64, or why RISC’s reductions would be good / bad / what trade-offs come with them.

        This is a purely theoretical arguement.

        Ecosystem momentum makes this argument mute.

      It’ll get there quick.

      I worked on HPC cpus, scaling up isn’t that hard, the hard part is dealing with your Isa baggage.

    Yeah, RISC is good.

      Wow, all the down votes. Youngin’s don’t know what they’re missing. Classic film.
