NVIDIA and AWS announced an expansion of their collaboration at AWS re:Invent, introducing NVIDIA NVLink Fusion for enhanced AI infrastructure. This integration will support new custom silicon, improve performance, and simplify deployment for advanced AI services. Additionally, they are launching AWS AI Factories for secure, sovereign AI solutions worldwide.

Amazon Web Services is set to unveil an updated Graviton4 chip featuring 600 gigabits per second of network bandwidth, the highest in the public cloud. This advancement positions AWS to compete more effectively against Nvidia in the AI infrastructure market, as the company aims to reduce AI training costs and enhance performance with its upcoming Trainium3 chip. AWS's focus on custom chips illustrates its strategy to dominate the AI infrastructure stack and challenge traditional semiconductor companies like Intel and AMD.
