On mobile devices efficiency is so important, I don't see how Qualcomm would be able to live without ARM licences. RISC-V and other architectures like x86-64 are nice, actually I think the peripheral libraries, boot and stuff like that are bigger headache to replace for Qualcomm's clients given that they can just switch the gcc to a different arch - still if your code is 25% less efficient, that'll be quite noticable for the consumer - or in your battery and weight costs.
What am I not seeing here? I think they'll just settle.
- notpushkin 2y agoYou're assuming there is something inherent to Arm specifically that makes it efficient. I'm not sure about that: it just evolved naturally as it was used in portable devices predominantly. Same thing can be done with RISC-V-based designs, but obviously it will take a lot of time.
- astrange 2y agoARMv8 is not an evolution of previous designs, it was created by and for Apple's phone SoCs. Whereas RISC-V was created by academics who mostly just claim it's the best because they invented it.
- snvzz 2y agoI suggest having a look into the actual pedigree of RISC-V, rather than making wild guesses. It might have been born in academia, but from those drafts until the first ratified spec there's a good decade of high quality input from distinguished industry veterans.
