Qwen 3.5 397B-A17B — MI355X vs TPU7x Performance per Dollar
Cost per million tokens of MI355X (AMD CDNA 4) versus TPU7x (Google Ironwood) on Qwen 3.5 397B-A17B. Large-hyperscaler-volume ownership TCO normalized by total 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.
MI355X costs $0.21 per million tokens at 70 tok/s/user on Qwen 3.5 397B-A17B; we have no TPU7x benchmark data at this exact target.
At 126 tok/s/user on Qwen 3.5 397B-A17B, MI355X comes in at $0.42 per million tokens. TPU7x hasn't been benchmarked at this operating point.
Only MI355X has cost data at 181 tok/s/user on Qwen 3.5 397B-A17B — $0.79 per million tokens. TPU7x is unmeasured at this target. (Numbers reflect the default 1k/1k · fp8 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.
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.
