Amazon CEO Andy Jassy dedicated a significant portion of the Q1 Earnings Call to discussing the company's in-house chip development. He stated that if the chip business were spun off and operated independently, selling chips externally like other Semiconductor companies, its annualized revenue would reach $50 billion. According to Jassy, Amazon's custom Silicon business has now become one of the top three data center chip businesses globally, achieving this status at an "extraordinary pace."
Supply and Demand for Four Generations of Trainium
The supply and demand situation for the four generations of TrAInium (Amazon's proprietary AI training chip) is as follows:
Trainium2: Completely sold out.
Trainium3: Just began shipping early this year, offering 30% to 40% better price-performance than Trainium2, and is nearly fully booked.
Trainium4: Scheduled for mass market release in APProximately 18 months, but more than half of its capacity has already been reserved.
Jassy noted that Trainium has accumulated over $225 billion in revenue commitments, including multi-year, multi-gigawatt training contrACTs from anthropic and OpenAI, as well as enterprise CLIents like Uber.
Cost Savings and Efficiency Gains
Jassy laid out the financial benefits:大规模 use of Trainium for inference saves Amazon tens of billions of dollars in CapEx annually compared to relying on external chips, with an operating margin advantage of several hundred basis points. A significant portion of the inference for Amazon Bedrock (AWS's model inference service, used by over 125,000 customers, including nearly 80% of Fortune 100 companies) already runs on Trainium.
Future Sales strategy
When asked about the possibility of selling Trainium racks directly, Jassy mentioned the need to balance satisfying existing customer demand with external sales but stated, "I expect we will likely start selling them in the coming years." AWS currently has a backlog of orders worth $364 billion, which does not include the multi-billion dollar deal with Anthropic announced last week.
