The reason to move away from arm has nothing to do with performance, but rather avoiding licensing snafus like happened with their laptop chips. So far no one has delivered a risc-v core with class leading performance outside of the really low end. Not saying it can’t be done, but it will likely be a step back at first.
I'm not a hardware specialist. Qualcomm already has their custom CPU core. Can't they just switch out the frontend (fetch/decode) with RISCV and the rest shouldn't be a be big problem?
Whats peoples thoughts on Tenstorrent - they were looking for funding on Hiive recently but that deal got pulled when Qualcomm rumours surface a week or so ago.
