I mean that isn't what I said at all. WHat I said was they currently have access to all of ARMs IP because that's how ARM operates. You don't need to spend 55billion when you can buy a license to the full IP they operate for <10million + tiny royalties per chip. In fact it's rather crazy to say that 55bililon so they can create a custom high speed desktop ARM chip is the reason they got it because they can literally achieve the same by buying the licence and putting together a team of engineers to design a custom core for a teeny tiny fraction of that pricing.
What I also said was I can't even tell what their entire goal is but that a large part of it, or most of it would be to diversify away from only selling graphics cards. Which doesn't preclude making higher and higher speed versions of ARM, I just said I don't think that is the primary goal nor would it be achieved successful in a short period of time like less than 3 years.
The assumption that “buying a license is all they need” is really our disagreement here.
Nvidia doesn’t have the skills to compete with Intel and AMD in the CPU space at this moment.
ARM, at this moment, doesn’t have anything Nvidia can license to compete with Intel and AMD. They however know how to make CPUs a lot better than Nvidia does.
ARM’s priorities, for the time being, are not to go all-in against Intel and AMD.
If Nvidia wants to be in the CPU space (otherwise why would they be interested in ARM), a merger/acquisition with ARM makes sense. ARM has the skills and talent to compete with Intel and AMD if their priorities were different. Nvidia can set those priorities after that acquisition.
Your whole “they can license it and it will be identical” point which you keep repeating is irrelevant. Nvidia can’t license a product that ARM doesn’t make. They can however instruct ARM to make it if they own it. They can also do what Apple did, buying smaller promising chip designers and attracting talent from everywhere to build up their own team, it will be more expensive and will take longer, but works. Apple had probably invested more than $55 billion in their chip design though.
And they won’t spend $55 billion out of their balance sheet for the acquisition themselves, all deals of this magnitude will be mergers. This merger makes no sense if it ends up diluting Nvidia by $55 billion to just earn $1 billion in profit a year (ARM’s profits last year). It must be strategic and product-oriented otherwise Nvidia’s board will be crazy to accept it.
