Nvidia said it’s acquiring chipmaker Arm from SoftBank for $40B. Arm will operate as Nvidia’s division and will continue to operate its open licencing model. But the deal is likely to face intense regulatory scrutiny. Arm will be headquartered in Cambridge, UK where Nvidia will build a new AI research centre. Both companies see this as growth opportunities in enabling AI software that can run on Arm’s chips from those on tiny smartphones to huge servers.
