The other is a programmable FP4 datacenter engine Huawei ships in 8,192-chip fabrics. Same goal, opposite theses: here’s what the M4 family actually is, and what the numbers do and don’t mean against the Ascend 950.https://hanhpham.vercel.app/posts/huawei-ascend-950-davinci-v3/Mon, 07 Sep 2026 09:00:00 +0700https://hanhpham.vercel.app/posts/huawei-ascend-950-davinci-v3/DeepSeek just ordered 160,000 Huawei Ascend 950DT chips: a chip built on a DUV-only process, with self-developed HBM and a homegrown interconnect, because export controls left no other choice.
