DeepSeek may unlock consumer GPU matmul performance with memory-bandwidth-first architecture

teortaxesTex · x · 2026-10-25

Commenter teortaxesTex speculates DeepSeek would have little trouble unlocking peak matmuls on RTX 3090/4090s, citing rumors of an internal single-consumer-GPU model, DeepSeek's memory-bandwidth-cheapest architecture, and experiment backbones under 22B. The thread builds on the argument that DeepSeek's core principle — compute is easy to scale, memory is hard — drives its model and infrastructure design, and its reported 80% gross margin economics.
