Amazon Web Services (AWS) is challenging the dominance of Nvidia and AMD in the artificial intelligence (AI) chip market by designing and manufacturing its own processors, starting with the Trainium series. The latest iteration, Trainium 3, boasts four times the speed and energy efficiency of its predecessor, potentially reducing the cost of developing and using AI models by 30-40% compared to traditional graphics processing units (GPUs).

Why it matters

The demand for computing power for AI is rapidly increasing, often exceeding supply. AWS and its Trainium chips offer a way for AI developers and cloud providers to diversify their supply chains, reducing reliance on Nvidia and AMD. This diversification is becoming increasingly important as the AI landscape evolves.

The details

AWS's journey into chip design began with the acquisition of Israeli startup Annapurna Labs in 2015. The company's latest Trainium 3 processor can reduce the cost of developing and using generative AI models by 30-40% compared to GPUs. AWS emphasizes the reliability of its chips, crucial for data centers operating continuously, and its vertically integrated approach, using the chips exclusively within its own cloud infrastructure and integrating them with its software platform, Bedrock.

  • Amazon acquired Annapurna Labs in 2015.
  • AWS released the Trainium 3 processor in December 2026.

What’s next

Development is already underway on the Trainium 4, with teams working in both Austin, Texas, and Cupertino, California. Mark Carroll, head of engineering at Annapurna Labs, anticipates the Trainium 4 will deliver six times the processing performance of the Trainium 3.

The takeaway

AWS's Trainium chips offer a cost-effective alternative to traditional GPUs for AI workloads, potentially reducing the cost of developing and using AI models by 30-40%. This diversification of the AI supply chain away from Nvidia and AMD is becoming increasingly important as the demand for computing power continues to grow.
