Kimi K2.5/K2.6/K2.7-Code 1T — B300 vs MI300X Performance per Dollar
Cost per million tokens of B300 (NVIDIA Blackwell) versus MI300X (AMD CDNA 3) on Kimi K2.5/K2.6/K2.7-Code 1T. 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 Kimi K2.5/K2.6/K2.7-Code 1T to 33 tok/s/user and B300 lands at $0.87 per million tokens against MI300X's $2.82 — B300 pulls ahead by 224%.
B300: $1.01 per million tokens. MI300X: $3.46. Both at 38 tok/s/user on Kimi K2.5/K2.6/K2.7-Code 1T, with B300 242% cheaper.
Toward the upper edge of the 28–48 tok/s/user interactivity band — at 44 tok/s/user — B300 runs $1.15 per million tokens on Kimi K2.5/K2.6/K2.7-Code 1T while MI300X runs $4.42. B300 is the cheaper choice by 283%. (Numbers reflect the default 1k/1k · int4 selection for this URL — table and chart below update if you change sequence, precision, or model in the controls.)

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.
