Head-to-head AI inference benchmark comparison of B200 (NVIDIA Blackwell) and TPU7x (Google Ironwood) on Qwen 3.5 397B-A17B. Latency, throughput, and cost across LLM workloads. Use the chart controls below to switch sequences, precisions, and metrics β 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 β
Setting 150 tok/s/user as the target on Qwen 3.5 397B-A17B, B200 produces 28875 tok/s/chip ($0.02 per million tokens) and TPU7x produces 37267 ($0.01). TPU7x is 117% cheaper per token; TPU7x delivers 29% more tok/s/chip.
At 218 tok/s/user interactivity on Qwen 3.5 397B-A17B, B200 delivers 20057 tok/s/chip at $0.02 per million tokens; TPU7x delivers 28082 tok/s/chip at $0.01. TPU7x is 135% cheaper per token; TPU7x delivers 40% more tok/s/chip at this point.
B200 posts 8352 tok/s/chip for $0.06 per million tokens at 286 tok/s/user on Qwen 3.5 397B-A17B; TPU7x posts 25822 tok/s/chip for $0.01. TPU7x is 419% cheaper per token; TPU7x delivers 209% more tok/s/chip.

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.
