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.

Memory Capacity and Bandwidth

These specifications affect model fit, KV-cache headroom, batch size and memory-bound workloads.

H200 vs A100 for LLM Inference

H200 has 61 GB more GPU memory, more than twice A100's listed memory bandwidth and native FP8. That gives it much more room for large model weights, KV cache, longer contexts and larger serving batches.

H200 vs A100 for AI Training

H200 combines Hopper Tensor Cores with 141 GB HBM3e, while A100 uses third-generation Ampere Tensor Cores and 80 GB HBM2e. For modern transformer training, H200 is the stronger technical platform.

H200 vs A100 for HPC

Both support MIG and NVLink, but H200 provides substantially higher memory bandwidth and a larger memory pool. A100 continues to be a capable HPC accelerator for workloads that do not need H200's extra memory.

Cloud Pricing

Compare Current Provider Pricing

There is no single cloud price for either GPU. Rates vary by provider, region, server configuration, billing model and commitment. Compare current provider offers after you know which hardware class fits the workload.

Final Decision

Should You Choose NVIDIA H200 or NVIDIA A100?

Choose NVIDIA H200 if:

  • You need more than 80 GB per GPU.
  • Memory bandwidth is limiting performance.
  • Your stack benefits from Hopper FP8.
  • You are targeting large-model inference or memory-intensive training.

Choose NVIDIA A100 if:

  • 80 GB is sufficient.
  • Your software estate is built around Ampere.
  • You do not need FP8.
  • A100 gives you better workload economics from the provider you use.

H200 vs A100 FAQs

Common questions about choosing between these NVIDIA GPUs.

Which is better, NVIDIA H200 or A100?
Choose H200 for large LLMs, memory-intensive inference, FP8 and higher-bandwidth training/HPC. Choose A100 for established Ampere workloads when 80 GB is sufficient and provider economics outweigh the newer Hopper capabilities.
What is the main difference between H200 and A100?
H200 uses Hopper with 141 GB HBM3e and 4.8 TB/s memory bandwidth, while A100 uses Ampere with 80 GB HBM2e and 2.039 TB/s. Tensor Core generation, precision support, interconnects and power can also differ.
Is H200 or A100 better for LLM inference?
H200 has 61 GB more GPU memory, more than twice A100's listed memory bandwidth and native FP8. That gives it much more room for large model weights, KV cache, longer contexts and larger serving batches.
Which GPU is better for AI training, H200 or A100?
H200 combines Hopper Tensor Cores with 141 GB HBM3e, while A100 uses third-generation Ampere Tensor Cores and 80 GB HBM2e. For modern transformer training, H200 is the stronger technical platform.
How much memory do H200 and A100 have?
NVIDIA H200 provides 141 GB HBM3e, while NVIDIA A100 provides 80 GB HBM2e. Memory capacity alone does not determine performance, so bandwidth, precision support and workload behavior should also be considered.
Which is cheaper to rent, H200 or A100?
Cloud rental pricing for H200 and A100 varies by provider, region, configuration and billing model. Check current provider pricing rather than assuming one GPU is always cheaper.
