Tightly integrated with Nvidia GPUs, the company’s first CPU is meant for the near future when AI models reach trillions of parameters.

The new designs aim at AI workloads and offer extra security features.

The groundswell of opposition may make it difficult to win approval, delay the process or force concessions that change the value of Arm to Nvidia.

The cloud giant adds to an industrywide effort to reduce reliance on Intel's chip technology.
