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 →
GB300 NVL72 costs $0.04 per million tokens at 139 tok/s/user on GLM 5.3 744B; we have no MI325X benchmark data at this exact target.
At 192 tok/s/user on GLM 5.3 744B, GB300 NVL72 comes in at $0.07 per million tokens. MI325X hasn't been benchmarked at this operating point.
Only GB300 NVL72 has cost data at 245 tok/s/user on GLM 5.3 744B — $0.10 per million tokens. MI325X is unmeasured at this target. (Numbers reflect the default agentic-traces · fp4 selection for this URL — table and chart below update if you change sequence, precision, or model in the controls.)
