Head-to-head AI inference benchmark comparison of MI355X (AMD CDNA 4) and RTX PRO 6000 (NVIDIA Blackwell) on Qwen 3.5 397B-A17B. 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.
AgentX replays real coding-agent sessions rather than fixed-length prompts, so context grows turn over turn and most of each request is served from cache instead of being recomputed. That turns the comparison into a systems question: KV transfer between nodes, prefix-aware routing, and cache capacity all move the curve alongside raw chip throughput. Fixed-sequence workloads stay the clean baseline for kernel and silicon performance, so the two scenarios answer different questions about the same hardware. Learn more about AgentX →
MI355X: 35493 tok/s/chip, $0.01 per million tokens at 93 tok/s/user on Qwen 3.5 397B-A17B. RTX PRO 6000 is unmeasured here.
At 159 tok/s/user on Qwen 3.5 397B-A17B, MI355X delivers 20007 tok/s/chip at $0.02 per million tokens; RTX PRO 6000 hasn't been benchmarked at this target.
MI355X hits 9578 tok/s/chip for $0.04 per million tokens at 224 tok/s/user on Qwen 3.5 397B-A17B. No RTX PRO 6000 data at this operating 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.

1 The ATOM engine is promising, however it has yet to serve production tokens. It is still in its infant stage.
