NVIDIA H100 vs A100 GPU Comparison: 2025 Analysis

Описание: The artice https://www.bestgpusforai.com/gpu-comparis... provides a detailed comparison of two generations of NVIDIA data center GPUs, the *A100 (Ampere architecture)* and the *H100 (Hopper architecture)**, focusing on their use in AI and High-Performance Computing (HPC). The H100 represents a significant performance leap, introducing features like the **Transformer Engine**, **FP8 precision**, and faster **HBM3 memory* and *NVLink interconnects* which lead to substantially higher throughput for large language models (LLMs). Conversely, the A100 remains a *better value* for budget-constrained projects or training mid-sized models, particularly through the used market, though it is now **end-of-life (EOL)**. The analysis covers architectural differences, **power efficiency (TDP)**, **cost of ownership (TCO)**, and performance benchmarks, concluding that the H100 is generally superior for demanding, large-scale 2025 workloads despite its higher price.
