Maybe. Other than Apple which is its own world, it remains to be seen if ARM will go anywhere on laptop/desktop. And aside from cloud servers, I see no evidence that ARM is making it in general purpose servers. Marvell's move just confirms that.That's where ARM is headed, if it can get traction. And it's headed for the server room, too. Or at least it's trying. Those are the markets where NV needs ARM the most - not RISC-V. NV is not looking at buying ARM to take over the smartphone market.
Anyway, this thread is explicitly about Nvidia possibly buying ARM, and people's worries about that. That means worries on mobile where it has a big presence, not PC/server where ARM designed cores have no presence (i.e. they are all closed systems and architectural licenses)
