MiniMax says AMD MI355X is nearing Nvidia B200 in serving
A repost from MiniMax claims AMD MI355X is now close to Nvidia B200 for serving MiniMax-M3.
The company says it published two technical blog posts describing a full-stack co-optimization of its ATOM + ATOMesh serving system for a 428B sparse MoE multimodal base model.
The post highlights several engineering changes:
- EAGLE3 speculative decoding to reduce generation latency
- MSA-aligned Page-16 KV cache for 1M ultra-long context
- Layer-wise FP8 quantization to avoid precision loss in vision/MoE components
- Distributed P/D separation for large-scale clusters
The main takeaway is that AMD hardware is getting closer to Nvidia performance in a real large-scale serving setup.
