Head-to-head AI inference benchmark comparison of B200 (NVIDIA Blackwell) and B300 (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
Setting 198 tok/s/user as the target on DeepSeek V4.1 Flash 552B, B200 produces 69297 tok/s/chip ($0.01 per million tokens) and B300 produces 92114 ($0.01). B300 is 2% cheaper per token; B300 delivers 33% more tok/s/chip.
At 323 tok/s/user interactivity on DeepSeek V4.1 Flash 552B, B200 delivers 29045 tok/s/chip at $0.02 per million tokens; B300 delivers 25254 tok/s/chip at $0.02. B200 is 50% cheaper per token; B200 delivers 15% more tok/s/chip at this point.
B200 posts 10121 tok/s/chip for $0.05 per million tokens at 449 tok/s/user on DeepSeek V4.1 Flash 552B; B300 posts 11265 tok/s/chip for $0.06. B200 is 17% cheaper per token; B300 delivers 11% more tok/s/chip.
