AMD Composability Issue on FP4, Distributed Inferencing and Wide Expert Parallelism

Evidence

While AMD performs somewhat decently on single node FP4 and performs competitively to B200 SGLang on FP8 distributed inferencing, the issue with the current AMD open source inferencing stack is that

② Atomic Claim

雖然 AMD 在 single-node FP4 表現尚可，FP8 distributed inferencing 搭配 SGLang 時也能與 B200 競爭，但 AMD 目前 open-source inference stack 的核心問題仍存在。
