Amazon has announced a strategic shift to directly sell its in-house AI chips, Trainium, to third parties, aiming to challenge NVIDIA's market dominance. CEO Andy Jassy revealed that this move could boost the chip division's annual revenue from $20 billion to $50 billion. The Trainium2 chip offers a 30% higher cost-performance ratio compared to competitors, and the upcoming Trainium3 is nearly fully subscribed before shipment. This initiative is part of Amazon's broader strategy to build a full-stack AI ecosystem, reduce reliance on NVIDIA GPUs, and address global AI compute shortages. By selling its chips, Amazon seeks to make computing power more accessible, potentially reshaping the competitive landscape of the AI hardware market.
