国产GPU的性能PK
傅里叶的猫· 2025-05-08 14:11
总体来看,910C在这三款卡中性能表现相对更优。 海光BW100作为一款全精度计算卡,其单卡可用 性能实测达到87%左右,而寒武纪590能否达到80%尚不确定。此外,海光BW100采用了较为先进的 交换芯片设计,在单卡上传方面表现良好。需要注意的是,寒武纪590推出时间 早于海光BW100, 因此后者在技术更新和优化上具有一定优势。 在本营的一个纪要中,曾给出了这样的性能排名:第一位是910C;第二位是海光BW100C;第三位 是华为910B;第四位是公司的卡(百度、阿里的自研卡);第五位是寒武纪;第六位包括沐曦和天 数智芯等其他厂商产品。其他大未测试过。 价格方面,目前市场上海光BW100目前采购价格约为10万元/张,而910B和910C分别为7万和18万元 左右。寒武纪590则从最初报价8 万-8.5万元下降至6万-7万元之间。 从显存上来看,国内GPU大部分最新的产品都是使用HBM2e,受制裁的影响,没办法使用最先进的 HBM3e。在推理任务中,显存是首要考虑的指标。推理模型在启动时需要足够的显存支持,如果显 存容量不足,模型将无法启动,这直接导致后续推理任务无法进行。只有在模型成功启动后,才会 进一步 ...

Morgan Stanley:中国 GPU的产能、良率、价格及收入
傅里叶的猫· 2025-05-07 12:11
总体而言,中国半导体自给率为 24%,高于我们的预期。根据高德纳(Gartner)的数据,中国半导 体公司的总收入为 430 亿美元,较 2023 年的 320 亿美元增长了 36%。中国半导体市场规模约为 1830 亿美元,占全球需求的 29%。因此,中国半导体自给率约为 24%,比 2023 年的 20% 提高了 4 个百分点。我们认为,中国半导体自给率的提升主要归因于以下几点:第一,政府对家电和消费电 子产品的补贴刺激了需求,与全球同行相比,中国半导体供应商在消费市场的曝光度相对较高;第 二,大多数中国半导体公司在 2023 年底或 2024 年上半年完成了库存消化,因此 2024 年中国半导体 公司的增长超过了外国同行;第三,存储芯片和先进节点产品(智能手机系统级芯片、GPU 等)的 产能提升和良率改善。 这篇文章是Morgan Stanley对中国GPU自给自足程度的研报的部分内容,最后那张图很有意思,把华 为昇腾系列GPU在2024到2027(预测)的产能、良率、价格、产量和收入情况都详细列了出来,相 信很多朋友对这个数据也都很有兴趣。报告原文放星球了。 正文 据我们估算,2024 年中国人工智能 ...

中芯国际的财务模型分析,成熟制程占比多少?
傅里叶的猫· 2025-05-04 15:32
Core Viewpoint - The article provides an in-depth analysis of SMIC (Semiconductor Manufacturing International Corporation), focusing on its financial model and growth prospects, particularly in the context of China's semiconductor policies and market dynamics [1]. Financial Indicators - Revenue is projected to grow from $2.07 billion in 2017 to $23.04 billion in 2028, with a compound annual growth rate (CAGR) of 24.8%, driven by the expansion of 28nm and above mature process capacities, especially post-2020 due to global chip shortages and domestic semiconductor policies [2]. - Gross margin is expected to increase from 21.2% in 2017 to 26.1% in 2028, benefiting from scale effects in mature processes, although it remains significantly lower than TSMC's 55% during the same period [2]. - EBITDA is forecasted to rise from $730 million to $12.17 billion, with EBITDA margin improving from 35.5% to 48.5%, indicating enhanced operational efficiency [2]. Capital Expenditure - Capital expenditures (Capex) are set to reach $7.326 billion in 2024, increasing to $8.69 billion in 2025 and peaking at $9.622 billion in 2026, reflecting a CAGR of 18.4% from 2017 to 2028, which is higher than the revenue growth rate [3]. - 90% of Capex is allocated to equipment procurement, primarily for mature process technologies, with 10% for wafer fab infrastructure [4]. - High Capex leads to significant depreciation costs, projected to reach $3.742 billion in 2024, which will pressure profit margins [4]. Business Structure - The wafer business is the core revenue driver for SMIC, contributing approximately 93.2% of total revenue in 2018, expected to rise to 95% by 2024 [7]. - Revenue from the 12/14nm nodes has shown rapid growth, from nearly negligible in 2019 to an estimated $838 million in 2024, driven by increasing market demand [8]. - The 28nm node remains a significant revenue contributor, with expected revenue of approximately $1.145 billion in 2024, despite facing competitive pressures [9]. Capacity and Market Competitiveness - Total capacity is projected to reach 884,000 wafers per month in 2024, increasing to 941,000 in 2025, with major production bases in Shanghai, Beijing, Shenzhen, and Tianjin [13]. - The Shanghai facility focuses on advanced processes, while the Beijing plant targets mature processes, with a significant portion of Capex directed towards expanding capacity in response to rising automotive electronics demand [13]. - Risks include potential impacts from U.S. sanctions on equipment maintenance and over-reliance on policy subsidies, which could lead to price competition [13]. R&D Investment and Technological Innovation - R&D expenditures are expected to rise to $1.031 billion in 2024, accounting for 9.4% of revenue, with a focus on optimizing 14nm FinFET processes and developing IoT chips [16]. - Despite increased R&D spending, challenges remain due to U.S. sanctions limiting access to advanced equipment, resulting in lower yield rates for 14nm processes [16]. - The company aims to balance high R&D intensity with policy requirements, although the return on investment in R&D is projected to be below the cost of capital, indicating diminishing marginal returns [17][18].
