DeepSeekv4 Pro 0813 1.6T — B200 vs MI355X
Head-to-head AI inference benchmark comparison of B200 (NVIDIA Blackwell) and MI355X (AMD CDNA 4) on DeepSeekv4 Pro 0813 1.6T. 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 →
Near the low end of the 20–117 tok/s/user interactivity band, at 44 tok/s/user on DeepSeekv4 Pro 0813 1.6T: B200 runs 25252 tok/s/chip at $0.02/M tokens, MI355X runs 12436 at $0.03/M. B200 is 76% cheaper per token; B200 delivers 103% more tok/s/chip.
Setting 69 tok/s/user as the target on DeepSeekv4 Pro 0813 1.6T, B200 produces 9281 tok/s/chip ($0.05 per million tokens) and MI355X produces 5964 ($0.07). B200 is 35% cheaper per token; B200 delivers 56% more tok/s/chip.
At 93 tok/s/user interactivity on DeepSeekv4 Pro 0813 1.6T, B200 delivers 6926 tok/s/chip at $0.07 per million tokens; MI355X delivers 3652 tok/s/chip at $0.11. B200 is 64% cheaper per token; B200 delivers 90% more tok/s/chip at this point.

Note: Disaggregated inference configurations (e.g., MoRI SGLang, Dynamo TRTLLM) calculate cost per million tokens per decode chip or per prefill chip, rather than per total chip count. This makes direct token cost comparison with aggregated configs not an apples-to-apples comparison.
