今天大家都在谈MS的这篇DeepSeek R2分析的报告,提前曝光了R2的性能和参数,我们简单总结一 下这个报告的核心内容: DeepSeek R2 使用了多达 1.2 万亿个参数,采用了新颖的架构,实现了运行成本的显著降低。其采用 混合专家混合(MoE)架构,有 780 亿个活跃参数。 并且R2 使用华为的 Ascend 910B 芯片进行训练,而非 NVIDIA 的芯片。 R2 增强了多语言覆盖能 力,能流畅处理非英语语言;扩展了强化学习,利用更大的数据集,使模型能够进行更具逻辑性和 更像人类的推理;增加了多模态功能,能够处理文本、图像、语音和视频数据;实现了推理时的缩 放,通过采用通用奖励模型(GRM),在推理过程中增加计算资源,从而提高了输出质量。 R2 具有高成本效益,输入成本为每百万代币 0.07 美元,输出成本为每百万代币 0.27 美元,而 R1 的 输入成本为 0.15-0.16 美元,输出成本为 2.19 美元。 由于这篇报告讲的人已经很多了,我们就不赘述了,而且报告也放到了星球中,有兴趣的朋友可以 到星球中看原文。 今天这篇文章来看另一篇AI的分析,Artificial Analysis ...
HBM 深度剖析
傅里叶的猫· 2025-06-04 11:43
Core Viewpoint - The article discusses the increasing importance of High Bandwidth Memory (HBM) in the AI chip sector, highlighting its advantages and the competitive landscape among major players like SK Hynix, Samsung, and Micron. Group 1: Importance of HBM - HBM is crucial in the era of generative AI as memory bandwidth often limits model training rather than computational power [4] - The memory demand in Transformer models grows quadratically with sequence length, making bandwidth a significant bottleneck [4] - HBM offers superior performance, with bandwidth reaching several terabytes per second, over 20 times faster than conventional DDR memory [5] Group 2: HBM Technology Development - Each generation of AI chip upgrades relies on HBM iterations for performance enhancement, with NVIDIA GPUs showing significant capacity increases [9] - HBM capacity has increased by 50% from H100 to H200 and B200 to B300, with HBM4 doubling the channel count from 8 to 16 [9] - The HBM market is expected to grow rapidly, with a projected CAGR of 50% from 2024 to 2028 [10] Group 3: Market Leaders and Competitive Landscape - SK Hynix currently leads the HBM market with over 60% market share, primarily supplying high-end HBM to NVIDIA [14] - The MR-MUF technology used by SK Hynix offers better thermal performance and higher yield compared to Samsung's TC-NCF technology [15][18] - Samsung faces challenges in HBM production due to issues with its front-end technology and lower yield rates [20][22] Group 4: Future Trends and Innovations - The shift from planar DRAM processes to advanced FinFET logic nodes in HBM4 is expected to enhance performance and energy efficiency [23] - Samsung plans to manufacture HBM4 base chips using its 4nm process, while SK Hynix and Micron will outsource to TSMC [25] - Hybrid bonding technology is emerging as a disruptive innovation in HBM, potentially changing the competitive landscape [32] Group 5: Chinese Market Developments - Chinese companies like ChangXin Memory Technologies (CXMT) and Yangtze Memory Technologies (YMTC) are making strides in HBM technology, although they currently lag behind global leaders [42] - CXMT aims to start mass production of HBM2 by late 2024, with plans for HBM3 and HBM3E in subsequent years [44] - The ability of Chinese firms to adopt hybrid bonding technology could significantly accelerate their HBM development [48][49]

从冷战时期的出口管制到AI芯片战
傅里叶的猫· 2025-06-03 14:38
Core Viewpoint - The article discusses the historical context of modern computing export restrictions, drawing parallels between the current US-China AI chip competition and the Cold War-era CoCom export control mechanisms, emphasizing the challenges of enforcement and the strategic implications for both nations [1][2][3]. Group 1: Historical Context - The CoCom (Coordinating Committee for Multilateral Export Controls) was established in 1949 as a response to the Soviet Union's nuclear capabilities, creating a comprehensive technology embargo system to control the export of strategic materials and technologies, particularly computing devices [3][4]. - The effectiveness of CoCom was undermined by non-compliance, disagreements among member countries, and the financial interests of technology exporters, leading to significant loopholes in enforcement [5][7]. Group 2: Current Implications - The current US perception of China mirrors the 1950s view of the Soviet Union, but the geopolitical landscape has changed significantly, with China possessing economic leverage and a more integrated role in the semiconductor supply chain [10][15]. - The article highlights that while CoCom faced execution challenges, the current semiconductor control efforts may encounter even greater difficulties due to the interconnected global trade networks and the economic ties of key partners with China [15]. Group 3: Lessons from CoCom - Effective technology restrictions require multilateral enforcement, as unilateral controls may have inherent limitations; historical examples show that coordination among major technology and manufacturing nations is crucial [14]. - A robust tracking and verification system is essential for effective enforcement of export controls, as past failures often stemmed from the inability to monitor the movement of controlled technologies [14]. - The article suggests that even under ideal conditions, CoCom struggled with execution, indicating that expectations for current export control measures may need to be adjusted given the complexities of today's geopolitical environment [14][15].

EDA禁售,国内的芯片设计公司如何应对?
傅里叶的猫· 2025-05-30 15:44
Group 1 - The core viewpoint is that there may still be room for negotiation regarding the EDA ban, as the current policy seems too extreme and unexpected [1] - Domestic EDA companies have made significant progress in covering various chip design, verification, and production scenarios, but there are still many bugs in their tools [2] - The notion that EDA bans will not affect many companies due to the use of pirated licenses is incorrect, as EDA tools are closely tied to foundry process design kits (PDK), which frequently update and validate licenses [3] Group 2 - Common strategies to cope with EDA tool shortages include registering overseas companies to purchase software and chips, establishing offshore R&D centers in regions with looser restrictions, and collaborating with foreign companies for production [7] - The best approach for acquiring IP is to buy it outright; if that is not feasible, companies must still rely on overseas sources [5]
如果EDA断供,国产EDA够用吗?
傅里叶的猫· 2025-05-29 15:16
Core Viewpoint - The article discusses the recent news regarding the supply disruption of EDA tools and emphasizes that a complete supply cut is unlikely, as it would signify a decoupling of the semiconductor industries between China and the U.S. The article also highlights the current dominance of three major EDA companies and the challenges faced by domestic EDA firms in China [1][3]. Industry Overview - The EDA industry is relatively small compared to other segments of the semiconductor industry, with the three leading companies—Synopsys, Cadence, and Siemens EDA—holding approximately 70% of the global market share. Synopsys accounts for about 32%, Cadence for 30%, and Siemens EDA for 13% [3][6]. - The largest EDA companies have market capitalizations around $70 billion, with Synopsys projected to generate revenues of $6 billion and net profits of $2 billion in 2024, indicating that EDA is not a high-margin industry [6][3]. EDA Tools and Market Segmentation - EDA tools are categorized into manufacturing EDA and design EDA, with manufacturing EDA being crucial for matching advancements in semiconductor process nodes [9][11]. - The Chinese manufacturing EDA market is expected to reach 4.22 billion yuan by 2028, with a compound annual growth rate (CAGR) of 21.2%, outpacing global growth due to increasing domestic demand [13]. Key Players in EDA - Synopsys has historically maintained a leading position in the EDA market, although it was recently surpassed in market value by Cadence. This shift is attributed to strategic moves, including the former CEO of Cadence joining Intel [15][18]. - Domestic EDA companies, while still lagging behind their U.S. counterparts, are numerous and competitive across various segments. However, only a few are expected to emerge as strong players due to the industry's limited size [19][28]. Domestic EDA Tools - Major domestic EDA companies like Huada Empyrean and others have developed comprehensive tools for analog IC design and wafer manufacturing, covering a wide range of processes [20][22]. - Despite the presence of domestic alternatives, there are significant gaps in quality and reliability compared to established foreign tools, leading many companies to prefer more expensive foreign solutions to mitigate risks [28][29].
