これは何か
H100 is a data-centre GPU NVIDIA announced in March 2022, based on the Hopper architecture. It carries 80GB of HBM3 memory, introduces fourth-generation tensor cores and a Transformer engine, and supports FP8 precision to raise throughput for large-model training and inference. Cards are linked by NVLink at 900 GB/s per GPU. H100 became one of the most widely used accelerators in large-model training clusters from 2022 to 2024.
なぜ覚えておく価値があるか
It baked large-model-specific features such as FP8 and the Transformer engine into hardware, becoming the default accelerator in large-model training clusters after 2022 and a symbol of compute as the industry’s bottleneck.
