Or in memespeak: scenes when nVidia controls Apple's CPU roadmap.
Historically I think they have just licensed the ISA and built their own thing on top. Maybe they needed the Big.Little stuff in the past but for the future they seem to be confident enough not to need anything from ARM or do it themselves.
You'd expect that ARM would be pretty responsive to the needs of one of its highest profile customers especially given the history and there is no reason why that would change with any sale.
Sure, Apple has escape routes if things go wrong but it's very very unlikely they will be needed.
So they probably could but whilst the relationship is good the best of all worlds is a strong ARM team plus a strong team in-house.
Even Qualcomm?
Why would they? With Intel, AMD, IBM with PowerPC, etc. CPU ISAs are not a monopoly.
Whoever buys ARM might want to do that to start cranking up licensing fees, and might not give a damn if this results in customer loses.
It doesn't seem to have hurt Apple in any of their past transitions.
The fact that Apple could improve their vertical integration by switching to their own silicon, doesn't mean that they need to control every single aspect of it. That rarely happens.
Also, any move by Nvidia to specifically hurt Apple would be not only detrimental to their own business, but likely an easy target for a lawsuit.
ARM was founded as a joint venture between Apple and Acorn, and Apple funded, helped design, and built their first joint ARM chip (the 610), and the ARMv3 architecture. I'd say they have a special relationship. They're the first licensee and like all the big names (Intel, Nvidia, Qualcomm, Samsung, etc.) have a far more permissive architectural license that allows them to extend the ISA or modify ARM cores as long as they comply fully with the ARM architecture. They also hold a lot of related patents.
So Apple is the last company that should worry about licensing (nothing to lose), or be interested in buying ARM (nothing to gain).
