GLM 5/5.1 — H200 vs MI355X

Head-to-head AI inference benchmark comparison of H200 (NVIDIA Hopper) and MI355X (AMD CDNA 4) on GLM 5/5.1. 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.

Near the low end of the 21–101 tok/s/user interactivity band, at 41 tok/s/user on GLM 5/5.1: H200 runs 329 tok/s/GPU at $1.19/M tokens, MI355X runs 755 at $0.54/M. MI355X is 120% cheaper per token; MI355X delivers 129% more tok/s/GPU.

Setting 61 tok/s/user as the target on GLM 5/5.1, H200 produces 212 tok/s/GPU ($1.85 per million tokens) and MI355X produces 367 ($1.11). MI355X is 67% cheaper per token; MI355X delivers 73% more tok/s/GPU.

At 82 tok/s/user interactivity on GLM 5/5.1, H200 delivers 132 tok/s/GPU at $2.93 per million tokens; MI355X delivers 229 tok/s/GPU at $1.81. MI355X is 62% cheaper per token; MI355X delivers 73% more tok/s/GPU at this point.
