Detailed Analysis

The TPU v5p and H100 represent fundamentally different approaches to AI acceleration. TPUs use a systolic array architecture optimised specifically for matrix operations, while the H100 is a general-purpose GPU with Tensor Cores.

The TPU v5p's greatest strength is scalability. It's designed for pod-based configurations that scale to thousands of chips with high-bandwidth interconnects, making it excellent for training very large models on Google Cloud.

The H100's advantage is versatility and portability. It excels at both training and inference, supports CUDA across all cloud providers, and benefits from NVIDIA's extensive software ecosystem. Workloads developed on H100 can run on any cloud provider.

TPU v5p is best suited for organisations committed to Google Cloud and working with JAX or TensorFlow. The H100 is the safer choice for organisations that need multi-cloud flexibility or use PyTorch as their primary framework.

Verdict

Best for Training

TPU v5p for large-scale distributed training on Google Cloud. H100 for flexibility and ecosystem breadth.

Best for Inference

H100 is more versatile for inference. Google also offers TPU v5 Lite for inference workloads.

Best Value

TPU v5p can be cost-competitive on Google Cloud. H100 for multi-cloud deployments.

Frequently Asked Questions

Should I use TPU or GPU for training?

If you're on Google Cloud and using JAX or TensorFlow, TPUs can offer excellent price/performance. If you need multi-cloud portability or use PyTorch heavily, GPUs (H100) are the safer choice.

Can I run PyTorch on TPUs?

Yes, through PyTorch/XLA. However, the experience is more mature on GPUs with CUDA. Some PyTorch operations may require adaptation for TPU compatibility.
