If a chip supplier like Nvidia buys ARM and uses its products, it will ultimately have an outsize say over ARM’s product (actually IP) roadmaps. That’s not going to make ARM’s current customers happy. Nvidia want to diversify- that’s why they’ve targeted ARM. They don’t need the technology- it’s readily available to licence.
Arm is valued at $40 billion on c. $ 2 billion in annual sales while Nvidia is valued at > $300 billion on $ 16 billion in sales. With a valuation of 300 billion, why buy ARM and almost certainly damage the ARM business model which is as an independent processor IP provider?
And how will Huawei (and China), big ARM licensees, react to ARM being owned by a US company given the bad blood in that area.
For ARM, it’s a strategic disaster IMV. Better to stay independent!
