DeepSeek‑V4 Inference Cost Showdown: NVIDIA H100 vs Ascend 950PR vs 910C

DeepSeek‑V4, a 1.6‑trillion‑parameter MoE model with mixed‑precision attention, is benchmarked on three accelerators—NVIDIA H100, Huawei Ascend 910C, and Ascend 950PR—showing that the 950PR delivers the lowest per‑token cost in both Prefill and Decode phases, while the H100 offers the highest raw performance at a far greater price.
