Head-to-head AI inference benchmark comparison of B200 (NVIDIA Blackwell) and H200 (NVIDIA Hopper) on DeepSeek V4.1 Flash 552B. Latency, throughput, and cost across LLM workloads. Use the chart controls below to switch sequences, precisions, and metrics β 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 β
Near the low end of the 73β320 tok/s/user interactivity band, at 134 tok/s/user on DeepSeek V4.1 Flash 552B: B200 runs 166120 tok/s/chip at $0.00/M tokens, H200 runs 12791 at $0.03/M. B200 is 816% cheaper per token; B200 delivers 1199% more tok/s/chip.
Setting 196 tok/s/user as the target on DeepSeek V4.1 Flash 552B, B200 produces 115427 tok/s/chip ($0.00 per million tokens) and H200 produces 8661 ($0.04). B200 is 840% cheaper per token; B200 delivers 1233% more tok/s/chip.
At 258 tok/s/user interactivity on DeepSeek V4.1 Flash 552B, B200 delivers 74607 tok/s/chip at $0.01 per million tokens; H200 delivers 5366 tok/s/chip at $0.06. B200 is 880% cheaper per token; B200 delivers 1290% more tok/s/chip at this point.
