Habana Gaudi2 delivers ~2x training/inference vs Nvidia A100 80GB — benchmarks with BERT, Stable Diffusion, T5-3B

AI Impact Summary

The article compares Habana Gaudi2 against Nvidia A100 80GB using SynapseAI and 🤗 Optimum Habana, highlighting substantial performance gains across training and inference. Gaudi2 delivers up to ~3x faster BERT pre-training versus Gaudi and roughly 1.7–2x throughput advantage over A100 80GB in several configurations, with Stable Diffusion latency significantly reduced and T5-3B fine-tuning enabled by 96GB per device memory. The transition is described as seamless due to SynapseAI compatibility, and Gaudi2's 96GB per-device memory enables larger batches and bigger models, though some memory bottlenecks (e.g., graph memory during the first iteration) may constrain batch size in certain runs. For teams evaluating hardware choices, the article suggests easy access via the Intel Developer Cloud and notes that existing Gaudi workflows will work without code changes using Optimum Habana.
