This is interesting, and if true I would just add that they would likely sell both cores – one RISC-V and one ARM – at least in the short term. Proof is that they have already taped out and anounced thier NUVIA based Snapdragon X desktop/laptop SoC. This would further incentivise compatibilty between ARM and RISC-V as this wouldn't be a one time port like Apple did with PA Semi. I would also add that this is all speculation.

That core as an AArch64 design is going to be stuck in the courts for longer than it'll be relevant. This work by Qualcomm seems to be a combo of trying to get anything out of the NUVIA acquisition, and maybe having a stick when negotiating a settlement with ARM ("we'll make your existential threat more real").

    I mean, I think we're seeing how the legal process works out. Getting an injunction takes time.
