Detailed Analysis
Trainium2 is AWS's latest custom AI training chip, representing a significant performance upgrade over the first-generation Trainium. AWS positions it as a cost-effective alternative to NVIDIA GPUs for training workloads within its ecosystem.
The Trainium2 benefits from AWS's ability to offer competitive pricing on instances using its own silicon. For supported workloads running on AWS, this can translate to meaningful cost savings compared to H100-based instances.
However, the H100's CUDA ecosystem remains unmatched in breadth and maturity. Most AI research, frameworks, and libraries are optimised first for CUDA, with AWS Neuron SDK support following. Organisations must weigh the cost savings against potential porting effort and ongoing compatibility considerations.
Trainium2 is most attractive for large-scale training workloads on AWS where the organisation has committed to the Neuron SDK ecosystem. The H100 remains the choice for maximum flexibility and performance.
Verdict
Trainium2 for cost-effective AWS-native training. H100 for peak performance and portability.
H100 or Inferentia2 (not Trainium2) for inference workloads.
Trainium2 can offer significant savings for supported workloads on AWS.
