Kimi K3 2.8T — B200 vs H200 Performance per Dollar
Cost per million tokens of B200 (NVIDIA Blackwell) versus H200 (NVIDIA Hopper) on Kimi K3 2.8T. Large-hyperscaler-volume ownership TCO normalized by total tokens — performance per dollar across LLM workloads. Pick the more cost-efficient SKU at every target interactivity level. 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 →
Near the low end of the 2–205 tok/s/user interactivity band — at 52 tok/s/user — B200 runs $0.11 per million tokens on Kimi K3 2.8T while H200 runs $4.85. B200 is the cheaper choice by 4393%.
On Kimi K3 2.8T at 104 tok/s/user, the per-million math comes out to $0.23 for B200 and $4.85 for H200; B200 delivers 2022% more total tokens per dollar.
At 155 tok/s/user on Kimi K3 2.8T, B200 costs $0.38 per million tokens; H200 costs $4.85. B200 is 1183% more cost-efficient at this operating point.
