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.

Amazon has announced the general availability of EC2 C8gn instances powered by Graviton4 processors, which offer up to 600Gbps network bandwidth, the highest among EC2 network optimized instances. These instances are designed for demanding network-intensive workloads and provide enhanced compute performance compared to previous Graviton3-based instances. C8gn instances are now available in select AWS regions and can be launched via various AWS tools.
