H100 vs H200 Specification Comparison

Core Specs: H100 vs H200

Key Highlights:

• Memory Capacity:
  H200 is equipped with 141 GB HBM3e memory, compared to 80 GB HBM3 on H100, offering approximately 76% more memory capacity, which significantly improves support for large language models and long-context AI workloads.

• Memory Bandwidth:
  With 4.8 TB/s memory bandwidth, H200 delivers about 43% higher bandwidth than H100’s 3.35 TB/s, reducing memory bottlenecks in memory-intensive AI training and inference tasks.

• Memory Technology:
  H200 upgrades from HBM3 to HBM3e, enabling both higher bandwidth and better efficiency, giving H200 a clear advantage in next-generation generative AI workloads.

• Memory Bus Width:
  H200 features a wider memory bus, allowing more data to be transferred per cycle, which directly benefits large-scale AI models that rely heavily on memory throughput.

• Compute Performance (FP32 & CUDA Cores):
  Both H100 and H200 offer the same CUDA core count and FP32 performance, meaning raw compute power remains comparable, and performance gains on H200 mainly come from memory improvements rather than core count.

• Tensor Core Capabilities:
  Both GPUs use the same Hopper-generation Tensor Cores, but H200’s larger and faster memory enables higher real-world AI inference throughput, especially for very large models.

• Power Efficiency Perspective:
  Despite its larger memory and higher bandwidth, H200 maintains a similar TDP to H100, resulting in better performance per watt for memory-bound AI workloads.

Advanced Features

Although NVIDIA H100 and H200 share similar compute architecture, H200 GPU is clearly optimized for large language model inference, offering higher throughput, longer context support, and better multi-tenant efficiency thanks to its larger and faster memory.

NVIDIA H100 vs H200 Benchmark for AI

Both NVIDIA H100 and H200 are designed for large-scale AI workloads, including AI inference and training. While their compute capabilities are similar, differences in memory capacity and bandwidth lead to noticeable performance gaps as model sizes and inference demands increase, especially in memory-intensive AI inference scenarios.

H100 vs H200 for AI Inference

Based on benchmark testing, the NVIDIA H200 significantly outperforms the H100 in large language model (LLM) inference. Thanks to larger memory (141 GB vs 80 GB) and higher HBM3e bandwidth, the H200 achieves significantly higher tokens/sec than the H100. For example, on Llama2‑13B, H200 reaches 11,819 tokens/sec, a ~ 90% increase over H100’s 6,221 tokens/sec; on Llama2‑70B, H200 hits 31,712 tokens/sec, roughly 42% higher than H100’s 22,290 tokens/sec. These results highlight H200’s clear advantage for memory-bound LLM inference, including long-context generation and high-concurrency deployments.

H100 vs H200 for AI Training

H200 provides a modest performance improvement of approximately +5% over H100 in AI training workloads, reflecting slightly higher memory bandwidth and GPU frequency. While H200 excels in memory-bound inference tasks, its training performance remains largely comparable to H100 in compute-bound scenarios.

Price & Value: Nvidia H100 vs H200

Value Proposition:

While the Nvidia H200 GPU carries a 7–10% premium over the H100 price, it offers measurable performance improvements in AI training and inference workloads. For users running large-scale models or high-throughput tasks, the slightly higher cost is offset by faster processing, improved efficiency, and better long-term value, making the H200 a compelling upgrade for organizations prioritizing performance per dollar.
