Choosing the right GPU for a machine learning pipeline can keep a project under budget or cause it to stall on compute limits. The NVIDIA A100 (Ampere) targets HPC and deep‑learning workloads, excelling at CNNs, inference, and multi‑tenant tasks via MIG, while the H100 (Hopper) is purpose‑built for generative AI, featuring a Transformer Engine that dynamically uses FP8 precision.
