NAND,也要迎来HBM时刻?
半导体行业观察· 2025-03-01 00:57
Core Viewpoint - NAND manufacturers are often overlooked in the AI boom, as their growth potential in AI applications is limited compared to DRAM, which is essential for AI computing needs [1][2][3] NAND Market Dynamics - AI computing primarily relies on DRAM due to its high bandwidth (up to 1TB/s) and low latency, while NAND's bandwidth (7-14GB/s) and higher latency make it less suitable for core AI tasks [1][2] - In AI training, NAND is mainly used for data storage rather than computation, leading to reduced demand once data is loaded into GPU DRAM [2] - The overall NAND market faces challenges such as easier capacity expansion and a larger number of competitors compared to DRAM, resulting in a more volatile market [3] Recent Market Trends - The NAND market experienced significant fluctuations in 2023, with a recovery in early 2024 driven by increased smartphone shipments and enterprise SSD demand due to AI server construction [5][6] - Global smartphone shipments rose by 8.2% year-on-year, and enterprise SSD procurement increased by 32% quarter-on-quarter, with North American cloud service providers accounting for 58% of global orders [5] - Strategic production cuts by major manufacturers like Samsung and Micron have led to a 17% increase in NAND Flash contract prices in Q1 2024 [5][6] Future Outlook - AI server SSD demand is expected to grow significantly, with predictions of over 45EB in procurement capacity in 2024 and an average annual growth rate exceeding 60% in the coming years [6][7] - The introduction of high-bandwidth flash (HBF) technology by SanDisk aims to provide a solution for AI inference applications, potentially positioning NAND to compete with HBM in the future [12][14] - The NAND industry is exploring various strategies, including enhancing storage density with QLC technology and dynamic capacity adjustments to address inventory issues [21][22] Competitive Landscape - The NAND market is characterized by a duality where enterprise demand is rising while consumer electronics face a downturn, leading to a stark contrast in performance across segments [8][9] - Companies are increasingly focusing on collaborative ecosystems and technology advancements to maintain competitiveness, with SK Hynix and Samsung leading in enterprise SSD markets [22][23]
GenAI 内存解决方案第 5 部分:DeepSeek 在芯片领域的高光时刻
Counterpoint Research· 2025-02-19 09:46
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 ...
