英伟达真正的对手是谁
经济观察报· 2025-12-23 11:22
英伟达并不缺少挑战者,但到目前为止,他们都很难称得上是 英伟达的对手,难以撼动其领导地位。不过,未来这一点未必 不会改变。 作者: 刘劲等 封图:图虫创意 算力是人工智能最重要的基础设施和发展引擎。AI算力的代表企业英伟达(NVIDIA)凭借性能先 进的产品和难以复制的生态,在AI训练及推理芯片领域建立起了近乎垄断的领导地位,成为地球上 价值最高的上市公司。截至2025年11月,英伟达的市值约为4.5万亿美元,2025年第三季度营收 的同比增长约为62%。 在大模型发展的初期和中期,训练算力是核心瓶颈,决定了模型的"高度",是算力芯片的战略制 高点。因此,我们在此着重讨论训练。 英伟达在训练算力上有统治性的地位。这种优势来自两个方面:先进的技术和生态的垄断。 主流大模型的参数规模已达千亿、万亿级别,训练时要对海量数据进行大规模计算,单机算力早已 远远不够,必须依托大规模芯片集群完成训练;要令这复杂而成本高昂的训练易于展开、效率高、 稳定可靠,还需要一整套的软件系统和工具来作为连接训练工程师、算力芯片和模型的桥梁。 因此,我们大致可以将训练对算力芯片的要求拆解成单芯片性能(单卡性能)、互联能力和软件生 态三部分 ...
拆解CANN:当华为决定打开算力的「黑盒」
机器之心· 2025-12-19 06:38
编辑|Panda、泽南 大模型的竞争如火如荼,也有一群人正在研究如何降低门槛,让 AI 工具变得亲民。 最近,在 AI 基础算力上重磅频出的华为,又亮出了一张王牌:昇腾的底层基础软件, CANN 全面开源开放 。 昇腾宣布将通过一系列新举措,持续支持开发者在 AI 模型、算子、内核、底层资源等多个层级进行自主优化与自定义开发。通过开放共建,一个新兴的 AI 算力生态正在快速崛起,改变计算架构领域本已固化的格局。 CANN 全称为「神经网络异构计算架构」(Compute Architecture for Neural Networks) ,其作为连接上层 AI 训练框架(如 PyTorch、 TensorFlow、MindSpore 等)和底层 AI 芯片的桥梁,让开发者不用关心芯片细节就能调用底层算力。 最近一段时间,业内对于国产 AI 算力的需求大幅增长,让人们更加重视起硬件的计算架构。CANN 的开源开放引发了业界的广泛关注,当 CANN 这个在 整个 AI 技术栈中「承上启下」的关键角色被开源了之后,开发者们获得了定义算力的权力。 以前在 AI 芯片上的算子开发门槛高到不敢用,现在昇腾 CANN 把这层 ...

Core Viewpoint - The ultimate competition in AI between China and the US may not be about computing power but rather about electricity supply, as AI's increasing demands for power will determine who can sustain their operations longer [5][10]. Group 1: US AI Industry Challenges - The bottleneck for the US AI industry has shifted from chip availability to electricity supply, with major tech companies struggling to secure sufficient power for their operations [9][10]. - AI applications, such as ChatGPT, consume significant amounts of electricity, with estimates indicating that daily operations could power 17,000 American households [11]. - The aging US power grid, built decades ago, is unable to meet the surging electricity demands, leading to potential power shortages in certain regions by 2030 [11][12]. Group 2: China's Energy Advantage - China is leveraging its energy advantages to compensate for product performance disadvantages in the AI sector, particularly through initiatives like "East Data, West Computing" [15][18]. - This initiative aims to transfer data processing from energy-rich western regions to eastern areas where demand is high, optimizing the use of clean and inexpensive electricity [16][18]. - The recent electricity subsidy for AI data centers in China is seen as a strategic move to enhance competitiveness against US firms by reducing operational costs [5][7][25]. Group 3: Cost Structure and Subsidies - The electricity subsidy fundamentally alters the cost structure for companies considering domestic chips, making it more attractive to switch from foreign to local alternatives [25][32]. - The new cost formula for AI operations in China now includes reductions in energy costs due to the "energy scheduling dividend" and fiscal subsidies, making domestic chips more competitive [31][32]. - The subsidy is designed to cover the ecological migration costs associated with transitioning to domestic chips, providing critical time for the development of local ecosystems [32]. Group 4: Strategic Implications - The combination of energy advantages, subsidies, and domestic chip development forms a closed-loop system aimed at challenging Nvidia's dominance in the AI ecosystem [33][40]. - As AI competition evolves from a focus on chip performance to resource management, China's ability to maintain lower operational costs could provide a significant competitive edge [41][45]. - The strategic focus is not only on defense but also on offensive maneuvers against established players like Nvidia, with the goal of redefining the competitive landscape [42][46].
