DeepSeek R1 — MI300X vs MI325X Performance per Dollar
Cost per million tokens of MI300X (AMD CDNA 3) versus MI325X (AMD CDNA 3) on DeepSeek R1. Owning-hyperscaler TCO normalized by output 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.
Push DeepSeek R1 to 39 tok/s/user and MI300X lands at $1.08 per million tokens against MI325X's $0.89 — MI325X pulls ahead by 21%.
MI300X: $1.53 per million tokens. MI325X: $1.29. Both at 49 tok/s/user on DeepSeek R1, with MI325X 18% cheaper.
Toward the upper edge of the 29–68 tok/s/user interactivity band — at 59 tok/s/user — MI300X runs $2.45 per million tokens on DeepSeek R1 while MI325X runs $2.18. MI325X is the cheaper choice by 12%.

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.
