AWS Trainium2 Chips Now Generally Available for AI Model Training
At its re:Invent 2024 conference, Amazon Web Services (AWS) announced the general availability of its next-generation Trainium2 (T2) chips, designed specifically for training and deploying large language models (LLMs). These powerful AI accelerators promise significant performance improvements over their predecessors, positioning AWS as a major contender in the competitive AI hardware space.
Unprecedented Performance for AI Workloads
The new Trainium2 chips deliver:
- 4X faster performance compared to first-generation Trainium chips
- 20.8 petaflops of compute power per EC2 instance (16-chip configuration)
- 3X higher token-generation throughput for massive models like Meta’s Llama 405B
- FP8 precision support for both dense and sparse models
“Trainium2 is the highest performing AWS chip created to date,” said David Brown, VP of Compute and Networking at AWS. “With models approaching trillions of parameters, we knew customers would need a novel approach to train and run those massive models.”
EC2 Trn2 UltraServers: Scaling AI Training
AWS is introducing powerful new instances called EC2 Trn2 UltraServers that feature:
- 64 interconnected Trainium2 chips
- Up to 83.2 peak petaflops of compute (FP8 sparse models)
- NeuronLink interconnect technology for efficient chip-to-chip communication
These UltraServers are currently in preview, with general availability expected soon.
Powering the Future of AI Development
AWS has partnered with Anthropic to create what it claims will be “the world’s largest AI compute cluster” featuring:
- Hundreds of thousands of Trainium2 chips
- 5X more powerful than Anthropic’s current training cluster
- Designed specifically for next-generation LLM development
The Competitive Landscape
While Trainium2 outperforms current-generation Nvidia GPUs in many benchmarks, Nvidia’s upcoming Blackwell platform promises even greater performance:
- Up to 720 petaflops of FP8 performance per rack
- Expected availability in early 2025
Looking Ahead: Trainium3 Coming in Late 2025
AWS isn’t resting on its laurels, already announcing Trainium3 with:
- Another 4X performance improvement over Trainium2
- Built on advanced 3-nanometer process technology
- Expected release in late 2025
Availability
Trainium2-powered EC2 instances are now generally available in AWS’s US East (Ohio) region, with additional regions coming soon. The UltraServer configurations remain in preview as AWS continues to optimize their performance.
