DeepSeek 的大语言模型(LLM)因其在性能上接近 ChatGPT ,但成本却大幅降低而受到关注。市 场的即时反应褒贬不一。虽然数据训练成本,比如数据标注和归类等方面的成本可能没有体现出 来,而这部分成本由政府支持,但 DeepSeek 在训练效率和低成本方面的优势依然十分明显。 DeepSeek 能否助力中国芯片制造? 中国的存储芯片或已具备成本竞争力 : 假设中国政府对构成总成本很大一部分的固定成本提供支持 ,那么与同行相比,中国已能实现有竞争力的成本。例如,2024 年第一季度 DRAM (动态随机存 取存储器)每 Gb ( 千兆字节 )的价格为 $0.34 ,此时高价的 HBM (高带宽存储器)对平均售价 的影响较小。而韩国 DRAM 的总成本大约为售价的 67% ,约为 $0.23 ,在不计固定成本的情况 下,中国的成本可能低至 $0.20 。(不过,中国的固定成本远高于韩国。) 高效的软件为低端硬件打开市场: 中国的策略是通过规模优势弥补与竞争对手在性能上的差距。华 为最新的 GPU —— Ascend 920 支持 HBM2 和 HBM2e ,而这些对于行业同行来说已是两年前的标 准,并未 ...
