Head-to-head AI inference benchmark comparison of B300 (NVIDIA Blackwell) and GB200 NVL72 (NVIDIA Blackwell) 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
B300 / GB200 NVL72 on DeepSeek V4.1 Flash 552B at 224 tok/s/user: 87187 / 61704 tok/s/chip, $0.01 / $0.01 per million tokens. B300 is 16% cheaper per token; B300 delivers 41% more tok/s/chip.
Around the middle of the 84β645 tok/s/user interactivity band, at 364 tok/s/user on DeepSeek V4.1 Flash 552B: B300 runs 39152 tok/s/chip at $0.02/M tokens, GB200 NVL72 runs 38365 at $0.01/M. GB200 NVL72 is 19% cheaper per token; B300 delivers 2% more tok/s/chip.
