NVIDIA A100 SXM (40GB) vs cheaper options for model training
💡 Answer
What is NVIDIA A100 SXM (40GB) good for? AI training, fine-tuning, inference on smaller models. Those are the natural fits given its specs: enough memory (40 GB) for most modern LLMs, enough compute for training at scale, and enough bandwidth to keep inference latency low.
NVIDIA A100 SXM (40GB) is not the cheapest option for small models, nor the largest option for frontier-scale training — but it occupies the highest-volume middle of the AI accelerator market, which is why it appears in most cloud catalogues at $0.80 per hour or better.
