MiniMax M3 428B — H200 vs MI300X

Head-to-head AI inference benchmark comparison of H200 (NVIDIA Hopper) and MI300X (AMD CDNA 3) on MiniMax M3 428B. 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 →

Setting 27 tok/s/user as the target on MiniMax M3 428B, H200 produces 3948 tok/s/chip ($0.09 per million tokens) and MI300X produces 975 ($0.27). H200 is 215% cheaper per token; H200 delivers 305% more tok/s/chip.

At 28 tok/s/user interactivity on MiniMax M3 428B, H200 delivers 3780 tok/s/chip at $0.09 per million tokens; MI300X delivers 957 tok/s/chip at $0.28. H200 is 207% cheaper per token; H200 delivers 295% more tok/s/chip at this point.

H200 posts 3495 tok/s/chip for $0.10 per million tokens at 29 tok/s/user on MiniMax M3 428B; MI300X posts 942 tok/s/chip for $0.28. H200 is 189% cheaper per token; H200 delivers 271% more tok/s/chip.

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.

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