Trainium — AI Training Chip

  • Deployment: 2.5 Million Chips projected 2024-2025
  • Purpose: Large Model Training
  • Cost/H100e: $7,200

Inferentia — AI Inference Chip

  • Optimized for: Production Inference
  • Use Cases: Low-latency, high-throughput (Alexa, Prime Video, Search)

Key Metrics

  • Compute Share: 10.9%
  • Revenue Share: 3.2%
  • Revenue: $9.7B
Low revenue share relative to compute share = aggressive internal cost optimization

2025 Capital Expenditure

  • Total CapEx: $125B
  • YoY Increase: +60%
  • Rank: #1 Largest hyperscaler spender

Internal Use Cases

  • Amazon.com: Product recommendations, search, personalization
  • AWS Services: Bedrock, SageMaker, customer AI workloads
  • Alexa & Devices: Voice AI, smart home, edge inference

The Amazon Strategy

  1. Internal First: Optimize AWS costs before external sales
  2. Reduce NVIDIA Dependency: Control costs and supply chain
  3. Massive Scale Advantage: 2.5M chips = internal optimization at scale

Anthropic Partnership

  • Investment: $8B+
  • Integration: Claude on AWS
  • Optimization: Trainium-tuned

Limitations

  • Internal focus limits scale
  • Less mature than TPU
  • Still NVIDIA-dependent for some workloads
