What Is the Main Difference Between NVIDIA H200 and NVIDIA A100?
H200 and A100 are separated by both architecture and memory generation. A100 uses Ampere with 80 GB HBM2e, while H200 uses Hopper with 141 GB HBM3e.
Memory bandwidth rises from 2.039 TB/s on A100 80 GB SXM to 4.8 TB/s on H200 SXM. H200 also adds Hopper Transformer Engine and native FP8 support that A100 does not provide.
The result is a substantial advantage for H200 on modern generative AI and memory-heavy workloads. A100 remains relevant where its established software support and potentially lower cloud rates are sufficient.
