Head-to-head AI inference benchmark comparison of MI300X (AMD CDNA 3) and MI325X (AMD CDNA 3) on Kimi K2.5/K2.6/K2.7-Code 1T. 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.
Near the low end of the 10–43 tok/s/user interactivity band, at 18 tok/s/user on Kimi K2.5/K2.6/K2.7-Code 1T: MI300X runs 416 tok/s/chip at $0.63/M tokens, MI325X runs 484 at $0.63/M. Cost per token is essentially tied; MI325X delivers 16% more tok/s/chip.
Setting 27 tok/s/user as the target on Kimi K2.5/K2.6/K2.7-Code 1T, MI300X produces 332 tok/s/chip ($0.79 per million tokens) and MI325X produces 427 ($0.72). MI325X is 11% cheaper per token; MI325X delivers 28% more tok/s/chip.
At 35 tok/s/user interactivity on Kimi K2.5/K2.6/K2.7-Code 1T, MI300X delivers 238 tok/s/chip at $1.11 per million tokens; MI325X delivers 302 tok/s/chip at $1.01. MI325X is 10% cheaper per token; MI325X delivers 27% 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.
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.
