Head-to-head AI inference benchmark comparison of B300 (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 — 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 →
Setting 100 tok/s/user as the target on DeepSeek V4.1 Flash 552B, B300 produces 58195 tok/s/chip ($0.01 per million tokens) and H200 produces 16626 ($0.02). B300 is 89% cheaper per token; B300 delivers 250% more tok/s/chip.
At 174 tok/s/user interactivity on DeepSeek V4.1 Flash 552B, B300 delivers 49036 tok/s/chip at $0.01 per million tokens; H200 delivers 9902 tok/s/chip at $0.03. B300 is 167% cheaper per token; B300 delivers 395% more tok/s/chip at this point.
B300 posts 29828 tok/s/chip for $0.02 per million tokens at 247 tok/s/user on DeepSeek V4.1 Flash 552B; H200 posts 5402 tok/s/chip for $0.06. B300 is 198% cheaper per token; B300 delivers 452% more tok/s/chip.
