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.

The U.S. government has announced new restrictions on the export of artificial intelligence chips from companies like Nvidia and AMD to China, aiming to hinder the country's advancements in AI technology. This move reflects a broader strategy by the Trump administration to combat China's growing capabilities in the tech sector.

Nvidia is working on a new AI chip built on its Blackwell architecture, aimed at outperforming its current H20 model available in China. Although U.S. President Trump has hinted at the possibility of allowing the sale of more advanced chips to China, regulatory approval remains uncertain due to security concerns. Samples of the new chip are expected to be delivered to Chinese clients as early as next month.
