DeepSeek V4.1 Flash 552B — H200 vs MI325X Performance per Dollar
Cost per million tokens of H200 (NVIDIA Hopper) versus MI325X (AMD CDNA 3) on DeepSeek V4.1 Flash 552B. 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. Use the chart controls below to switch sequences, precisions, and metrics — 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 →
H200: $0.01 per million tokens. MI325X: $0.02. Both at 61 tok/s/user on DeepSeek V4.1 Flash 552B, with H200 46% cheaper.
Around the middle of the 10–215 tok/s/user interactivity band — at 112 tok/s/user — H200 runs $0.02 per million tokens on DeepSeek V4.1 Flash 552B while MI325X runs $0.03. H200 is the cheaper choice by 48%.
On DeepSeek V4.1 Flash 552B at 164 tok/s/user, the per-million math comes out to $0.03 for H200 and $0.07 for MI325X; H200 delivers 129% more total tokens per dollar.
