MiniMax M3.1 Flash 428B — H200 vs MI355X Performance per Dollar
Cost per million tokens of H200 (NVIDIA Hopper) versus MI355X (AMD CDNA 4) on MiniMax M3.1 Flash 428B. Large-hyperscaler-volume ownership TCO normalized by total tokens — performance per dollar across LLM workloads. Pick the more cost-efficient SKU at every target interactivity level.

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 →
H200: $0.04 per million tokens. MI355X: $0.01. Both at 98 tok/s/user on MiniMax M3.1 Flash 428B, with MI355X 329% cheaper.
Around the middle of the 34–294 tok/s/user interactivity band — at 164 tok/s/user — H200 runs $0.05 per million tokens on MiniMax M3.1 Flash 428B while MI355X runs $0.02. MI355X is the cheaper choice by 173%.
On MiniMax M3.1 Flash 428B at 229 tok/s/user, the per-million math comes out to $0.08 for H200 and $0.02 for MI355X; MI355X delivers 244% more total tokens per dollar.
