Qwen 3.5 397B-A17B — H100 vs H200

Head-to-head AI inference benchmark comparison of H100 (NVIDIA Hopper) and H200 (NVIDIA Hopper) on Qwen 3.5 397B-A17B. Latency, throughput, and cost across LLM workloads. Use the chart controls below to switch sequences, precisions, and metrics — same interactions as the main inference chart.

AgentX replays real coding-agent sessions rather than fixed-length prompts, so context grows turn over turn and most of each request is served from cache instead of being recomputed. That turns the comparison into a systems question: KV transfer between nodes, prefix-aware routing, and cache capacity all move the curve alongside raw chip throughput. Fixed-sequence workloads stay the clean baseline for kernel and silicon performance, so the two scenarios answer different questions about the same hardware. Learn more about AgentX →

At 82 tok/s/user interactivity on Qwen 3.5 397B-A17B, H100 delivers 3675 tok/s/chip at $0.09 per million tokens; H200 delivers 9135 tok/s/chip at $0.04. H200 is 138% cheaper per token; H200 delivers 149% more tok/s/chip at this point.

H100 posts 3259 tok/s/chip for $0.10 per million tokens at 111 tok/s/user on Qwen 3.5 397B-A17B; H200 posts 7110 tok/s/chip for $0.05. H200 is 109% cheaper per token; H200 delivers 118% more tok/s/chip.

Throughput at 141 tok/s/user on Qwen 3.5 397B-A17B: H100 hits 2617 tok/s/chip, H200 hits 5419. Per-million costs land at $0.12 and $0.06 respectively. H200 is 99% cheaper per token; H200 delivers 107% more tok/s/chip.

Note: Disaggregated inference configurations (e.g., MoRI SGLang, Dynamo TRTLLM) calculate cost per million tokens per decode chip or per prefill chip, rather than per total chip count. This makes direct token cost comparison with aggregated configs not an apples-to-apples comparison.

Note: Disaggregated inference configurations (e.g., MoRI SGLang, Dynamo TRTLLM) calculate input throughput per decode chip or per prefill chip, rather than per total chip count. This makes direct input throughput comparison with aggregated configs not an apples-to-apples comparison.
