Head-to-head AI inference benchmark comparison of H100 (NVIDIA Hopper) and MI300X (AMD CDNA 3) on Llama 3.3 70B. 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.
H100 posts 1848 tok/s/chip for $0.18 per million tokens at 38 tok/s/user on Llama 3.3 70B; MI300X posts 1787 tok/s/chip for $0.15. MI300X is 19% cheaper per token; H100 delivers 3% more tok/s/chip.
Throughput at 58 tok/s/user on Llama 3.3 70B: H100 hits 1171 tok/s/chip, MI300X hits 1144. Per-million costs land at $0.28 and $0.23 respectively. MI300X is 20% cheaper per token; H100 delivers 2% more tok/s/chip.
H100 / MI300X on Llama 3.3 70B at 78 tok/s/user: 877 / 688 tok/s/chip, $0.37 / $0.38 per million tokens. H100 is 3% cheaper per token; H100 delivers 27% 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.

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