此外,英特尔与英伟达的合作项目距离实际落地尚需数年时间。不过摩根士丹利分析师补充称,半导体 行业这一"结构性变革","恰恰凸显了'芯片互联技术'的重要性,以及'机架级计算'模式的优势"。 目前市场存在一种担忧:若NVLink技术延伸至x86领域,可能会取代x86架构CPU与英伟达GPU之间传 统的PCIe接口连接方式——而Astera Labs的产品中包含大量PCIe相关技术及组件,这一变化或将对其业 务造成冲击。不过,现阶段我们尚不宜得出明确结论。" 尽管Astera Labs被列为NVLink Fusion技术的合作方,未来仍有可能在该技术生态中保留业务参与空 间,但具体合作细节目前仍不清晰。 智通财经APP获悉,摩根士丹利表示,英特尔(INTC.US)与英伟达(NVDA.US)达成的PC及数据中心芯片 联合研发协议,可能会对Astera Labs(ALAB.US)产生重大影响,但目前尚无法明确具体影响方向及程 度。 摩根士丹利分析师在致客户的报告中指出:"尽管今年早些时候英伟达发布NVLink Fusion技术的首批公 告中并未提及英特尔,但我们始终认为,这项技术是英伟达为抢占更大规模'服务器x86架构 ...

Core Insights - The dialogue between Alibaba Cloud's founder Wang Jian and Nvidia's CEO Jensen Huang signals a shift in AI discussions from parameters and data to a more physical interaction with the real world, indicating the emergence of a "physical AI" stage [1][2] Group 1: Transition to Physical AI - Huang predicts that the next wave of AI will enter the "physical AI" era, where AI will possess a complete capability chain from perception to action in the physical world, including applications like humanoid robots and autonomous driving [2][3] - Physical AI emphasizes interaction with real-world scenarios, requiring AI systems to autonomously understand and respond to uncertain physical environments, thus increasing demands for multimodal perception and real-time responsiveness [2][3] Group 2: Changes in Model Training - The transition to physical AI marks a shift in model training logic, moving from reliance on large datasets for pre-training to a focus on "post-training" and fine-tuning, with reinforcement learning becoming crucial for aligning AI behavior with human intentions [3][4] - The demand for computational power will escalate significantly, impacting the entire upstream value chain, as hardware manufacturers with multimodal input capabilities will become central to AI systems [3][4] Group 3: Cloud Computing Adjustments - The exponential growth in computational demands will lead to a standardization of IaaS as a fundamental infrastructure, while the SaaS layer will evolve into lighter interfaces, shifting differentiation back to business logic and product experience [4] - The evaluation of large models will transition from a focus on parameter size to a comprehensive assessment of performance across various capabilities, such as handling long texts and multi-step reasoning [4] Group 4: AI in Manufacturing - Future AI applications are expected to center around manufacturing, with AI not only controlling production lines but also being embedded directly into product forms, leading to a new category of devices that integrate physical AI [5] Group 5: Key Themes of Open Source and Bioengineering - The importance of open source in AI development is highlighted, evolving from a technical debate to a strategic and ecological choice as AI systems require customization and adaptability to diverse real-world scenarios [6][7] - Nvidia's push for open source is exemplified by its NVLink Fusion technology, which encourages interoperability with third-party hardware, indicating a shift towards building a comprehensive ecosystem around AI models [9][10] Group 6: Future Strategies of Nvidia and Alibaba Cloud - Nvidia is transitioning from a chip manufacturer to an AI infrastructure builder, exemplified by its investment in CoreWeave, which provides high-performance GPU cloud services [11][12] - In contrast, Alibaba Cloud is adapting to pressures from upstream hardware manufacturers by integrating IaaS and PaaS, aiming to evolve from a resource provider to a product provider, thus enhancing its ecosystem capabilities [13][14]
ASIC大热,英伟达慌吗?
半导体行业观察· 2025-06-23 02:08
Core Viewpoint - Meta is entering the ASIC market to compete with Nvidia, with plans to launch millions of high-performance AI ASIC chips by 2026, potentially challenging Nvidia's long-standing market dominance [1][2]. Group 1: Meta's MTIA Plans - Meta's MTIA project aims to release its first ASIC chip, MTIA T-V1, in Q4 2025, designed by Broadcom with a complex 36-layer PCB and hybrid cooling technology [3][8]. - By mid-2026, the MTIA T-V1.5 will double in chip area and approach Nvidia's GB200 system in computational density [3][8]. - The MTIA T-V2, expected in 2027, will feature larger CoWoS packaging and a high-power (170KW) rack design [3][8]. Group 2: ASIC Market Rise - Nvidia currently holds over 80% of the AI server market, while ASICs account for only 8-11% [7]. - By 2025, Google's TPU shipments are projected to reach 1.5-2 million units, and AWS's Trainium 2 ASICs are expected to be around 1.4-1.5 million units, potentially matching Nvidia's GPU shipments [2][15]. - With Meta and Microsoft set to deploy their ASIC solutions, total ASIC shipments may surpass Nvidia's GPU shipments by 2026 [2][15]. Group 3: Challenges and Risks - Meta's goal of 1-1.5 million ASIC shipments by late 2025 to 2026 may face delays due to wafer allocation limitations, which currently support only 300,000 to 400,000 units [4][15]. - The technical challenges of large CoWoS packaging and system debugging, which can take 6-9 months, add uncertainty to Meta's plans [4][15]. - A simultaneous acceleration in deployment by Meta, AWS, and other cloud service providers could lead to shortages of high-end materials and components, increasing costs [4][15]. Group 4: Nvidia's Advantages - Nvidia is not idle; it has introduced NVLink Fusion technology to strengthen its market position by allowing seamless connections between third-party CPUs or xPUs and its AI GPUs [5][15]. - Nvidia maintains a lead in chip computational density and interconnect technology, making it difficult for ASICs to catch up in the short term [5][15]. - The CUDA ecosystem remains the preferred choice for enterprise AI solutions, presenting a significant barrier for ASICs to overcome [5][15].
