GLM 5.3 744B — H200 vs MI355X Performance per Dollar
Cost per million tokens of H200 (NVIDIA Hopper) versus MI355X (AMD CDNA 4) on GLM 5.3 744B. Owning-hyperscaler TCO normalized by output tokens — performance per dollar across LLM workloads.

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 →
Only MI355X has cost data at 49 tok/s/user on GLM 5.3 744B — $0.03 per million tokens. H200 is unmeasured at this target.
MI355X costs $0.06 per million tokens at 85 tok/s/user on GLM 5.3 744B; we have no H200 benchmark data at this exact target.
At 122 tok/s/user on GLM 5.3 744B, MI355X comes in at $0.09 per million tokens. H200 hasn't been benchmarked at this operating point. (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.)
