Nvidia decided to abandon its pursuit of Arm at board meeting earlier on Monday, said a person familiar with the discussion. Its pursuit of Arm marked an opportunistic attempt to score an end-run around chip rivals such as Intel and AMD, and was prompted by an approach from SoftBank after the Japanese company decided to shed the business. Jensen Huang, Nvidia’s chief executive, hoped to use Arm’s processor designs to cement his company’s growing role in data centres, where its graphical processors have become important tools for machine learning.
