AI Performance Analysis of DeepSeekV4 Semiconductors Over 43 Days – MI355X, GB300 NVL72, B200
Technology Overview DeepSeek V4 introduces attention mechanisms such as Compressed Sparse Attention (CSA)and Heavily Compressed Attention (HCA), targeting reduced KV cache requirements. The design aims to support extended context lengths (up to 1M tokens),with the paper reporting significant cache reduction under these conditions. The architecture also includes a fused MoE kernel (MegaMoE),which schedules expert computation […]
