DeepSeek V4.1 Flash 552B Β· Chip comparison

DeepSeek V4.1 Flash 552B β€” B200 vs H200

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 50–320 tok/s/user interactivity band, at 117 tok/s/user on DeepSeek V4.1 Flash 552B: B200 runs 162546 tok/s/chip at $0.00/M tokens, H200 runs 14646 at $0.02/M. B200 is 683% cheaper per token; B200 delivers 1010% more tok/s/chip.

Setting 185 tok/s/user as the target on DeepSeek V4.1 Flash 552B, B200 produces 116446 tok/s/chip ($0.00 per million tokens) and H200 produces 9308 ($0.04). B200 is 782% cheaper per token; B200 delivers 1151% more tok/s/chip.

At 253 tok/s/user interactivity on DeepSeek V4.1 Flash 552B, B200 delivers 42932 tok/s/chip at $0.01 per million tokens; H200 delivers 5380 tok/s/chip at $0.06. B200 is 463% cheaper per token; B200 delivers 698% more tok/s/chip at this point.
