AI ASIC加速增长,全球龙头指引成长空间广阔
2025-08-27 15:19
2025 年,AI ASIC(专用集成电路)在整个芯片行业中扮演着越来越重要的角 色。尤其是在 AI 芯片市场,ASIC 因其在特定场景和任务需求上的产品匹配优 势,表现出显著的业绩增长。ASIC 芯片通常为特定目的或算法专门定制,能够 在特定任务上发挥强大的算力。例如,在深度学习算法中,ASIC 可以更高效地 进行矩阵运算和数据处理。 相比之下,GPU 虽然综合能力较强,但功耗和成本 也较高。因此,在满足不同下游客户需求时,ASIC 和 GPU 各有优劣。随着 AI 整体向推理侧发展及应用功能的丰富化,相对单一任务集中解决方案的 ASIC 将成为重要选择。此外,在设计路径上,不仅要提升算力,还需兼顾高速通信 能力,这是影响集群整体性能的重要因素。 海外互联网厂商自研 ASIC 进度加快,与博通、Marvell 等紧密合作,普 遍采用 sky up 或机柜连接方式,光模块需求随网络升级而提升,对国 内市场有重要启示。 博通 AI 业务收入占比快速提升,核心竞争力在于领先的 IP 储备、深耕 网络层多年以及超大规模芯片落地能力,Marvell 在 AWS 产品中逐步成 为主要对接厂商,数据中心业务市场空间预期上 ...

三个月、零基础手搓一块TPU,能推理能训练,还是开源的
机器之心· 2025-08-24 04:02
Core Viewpoint - The recent advancements in large model technology have renewed interest in AI-specific chips, particularly Google's TPU, which has evolved significantly since its deployment in 2015, now reaching its 7th generation [1][9]. Group 1: TPU Overview - TPU is a specialized chip designed by Google to enhance the speed of machine learning model inference and training, focusing on executing mathematical operations efficiently [9]. - The architecture of TPU allows it to perform matrix multiplication efficiently, which constitutes a significant portion of computations in deep learning models [14][31]. Group 2: TinyTPU Project - The TinyTPU project was initiated by engineers from Western University in Canada to create an open-source ML inference and training chip, motivated by the lack of a complete open-source codebase for such accelerators [5][7]. - The project emphasizes a hands-on approach to learning hardware design and deep learning principles, avoiding reliance on AI tools for coding [6]. Group 3: Hardware Design Insights - The project team established a design philosophy of exploring unconventional ideas before consulting external resources, leading to the re-invention of many key mechanisms used in TPU [6]. - The hardware design process involves understanding clock cycles, using Verilog for hardware description, and implementing a systolic array architecture for efficient matrix multiplication [10][12][26]. Group 4: Training and Inference Mechanisms - The TinyTPU architecture allows for continuous inference by utilizing a double buffering mechanism, which enables the loading of new weights while processing current computations [61][64]. - The training process leverages the same architecture as inference, with additional modules for gradient calculation and weight updates, allowing for efficient training of neural networks [71][118]. Group 5: Control and Instruction Set - The control unit of TinyTPU employs a custom instruction set architecture (ISA) to manage control signals and data flow, enhancing the efficiency of operations [68][117]. - The ISA has evolved to include 94 bits, ensuring that all necessary control flags and data fields are accounted for without compromising performance [117].

谷歌技术报告披露大模型能耗:响应一次相当于微波炉叮一秒
量子位· 2025-08-22 05:51
时令 发自 凹非寺 量子位 | 公众号 QbitAI 大模型耗电惊人,舆论一浪高过一浪。 现在,谷歌用硬核数据强势还击。 一次Gemini查询仅能耗0.24wh, 相当于微波炉运行1秒 ,排放0.03 g CO₂e,甚至 比人放一次屁还少 ,同时消耗约5滴水。 (文中数据均表示中位数) 谷歌首席科学家Jeff Dean公开表示: 这个数值明显低于公众普遍预期的水平。 若Gemini只考虑TPU和GPU的消耗,一次查询只需消耗0.10wh,排放0.02 g CO₂e,耗水量约0.12ml。 但这种计算方式仅考虑了机器在运行中的能耗,而忽略了一些关键因素。 并且像谷歌这样的大模型厂商,一直专注研究如何降低AI消耗。 一年间,通过模型优化和额外清洁能源的使用,Gemini的能耗降至原来的1/33,碳排放降至1/44,同时提供了更高质量的响应。 下面让我们一起看看谷歌是如何衡量和减少AI能源消耗的? 如何衡量AI消耗能源 谷歌首先指出,目前许多关于AI能源消耗的计算反映的都是理论效率,而非大规模运行下的实际效率。 | | Active Al Accelerators | | | | | | --- | --- | - ...
英伟达占标准普尔 500 指数的 8%——历史表明,野兽模式或将结束
美股研究社· 2025-08-19 12:44
Core Viewpoint - Nvidia (NASDAQ: NVDA) is facing significant challenges ahead, including high valuation and unprecedented competition, despite its current success in the AI and robotics sectors [1][2]. Valuation Concerns - Nvidia's stock price has doubled since its low in April, indicating it is currently overbought and may be due for a correction [2]. - The stock is trading well above its 50-day moving average (approximately $163) and 200-day moving average (approximately $136) [2]. - Analysts express skepticism about the stock's future performance given its high price-to-earnings ratio exceeding 40 [9]. Competitive Landscape - Major tech companies are developing their own AI chips, posing a significant threat to Nvidia: - Google has developed TPU and plans to release new AI chips in 2024 and 2025 [5]. - Microsoft is working on Azure Maia AI Accelerator and Azure Cobalt CPU for its data centers [6]. - Amazon has its own AI chips, "Trainium" and "Inferentia," for training and inference tasks [7]. - Emerging companies like Cerebras Systems, Tenstorrent, and Graphcore are also entering the AI chip market, potentially disrupting Nvidia's dominance [8]. Market Influence - Nvidia currently accounts for approximately 8% of the S&P 500 index, which raises concerns about its influence on the overall market [8]. - The historical context shows that no chip company has maintained a leading position in the S&P 500 for an extended period, indicating potential volatility for Nvidia [15]. Historical Performance and Future Outlook - Historical trends suggest that past performance does not guarantee future results, and Nvidia's current valuation may not be sustainable [9][10]. - The company is attempting to diversify its business, which could stabilize its position in the long term, similar to Microsoft [14]. - Analysts suggest that the current high stock price may present an ideal selling opportunity before the upcoming earnings report [14].
