And this is just idle speculation and I (and I guess Animats) don't necessarily buy. I think RISC-V is doing fine and will grow regardless.
Where more Arm mainstream success will have a slipstream effect on RISC-V is in app porting. There are significant differences between x86 and Arm, notably memory model (AS does support TSO with a flag, but native apps use the weak mode). Porting from x86 to Arm can be non-trivial, whereas porting from Arm to RISC-V is far easier.
- socialdemocrat 6y agoAs mentioned in the article Nvidia has selected RISC-V to use in their graphics cards after careful evaluation of alternatives. RISC-V beat all the alternatives. A lot of other accelerator card makers are reaching the same conclusions. You can google and find many white papers detailing how RISC-V is getting incorporated into accelerators/coprocessors with great success.
- FullyFunctional 6y agoI'm aware of this (I've been doing since RISC-V before it was public), but it seems unlikely to me, knowing how these companies operate, that Apple would use RISC-V for anything when they already have extensive HW and SW Arm64 IP, expertise, and infrastructure. NVIDIA's use of RISC-V is for the internal power sequencing cores and similar tasks. This is not going into the shaders, nor is Arm64. Their future use of RISC-V for stuff like this will probably continue, but it seems unlikely that they will ever release anything with a user-visible ISA based on RISC-V.
