国产算力破局!资本狂砸 3D 芯片!市场空间多大?
是说芯语· 2026-03-02 12:54
算苗科技的快速融资,本质上是资本市场对 3D 算力芯片技术价值的精准判断。长期以来,"内存墙" 是制约 AI 算力释放的核心瓶颈:过去 20 年,芯片计 算能力随摩尔定律增长 6 万倍,而内存带宽仅增长 100 倍,互连带宽更是仅增 30 倍,英伟达 H100 跑 AI 推理时甚至有 70% 计算单元因等待数据空转。 算力需求与数据传输效率的巨大落差,让突破内存带宽限制成为 AI 芯片产业的核心课题。 与传统 2D IC 的平面布局、2.5D IC 的中介层互连相比,3D IC 通过硅通孔、混合键合等技术实现存储与计算芯片的垂直高密度堆叠,彻底打破了 "Beach Front" 带宽上限,实现了极致的内存带宽与集成密度。算苗科技的 3D TokenPU 架构正是这一技术的典型应用,其 3D DRAM 带宽达 32TB/s,是英伟达 B200 的 4 倍,首款芯片 A4 在主流开源大模型上的推理吞吐量更是达到英伟达 H200 的 1.26-2.19 倍,且采用 12nm 工艺却实现了对台积电 4nm 工艺产品 的性能超越,单价低 30% 同时毛利率超 60%,完美契合了 AI 产业对 "高性能 + 低成本" 算 ...

未知机构· 2026-02-27 02:25
Summary of Conference Call Notes Industry Overview - The conference call discusses the CPU industry, particularly focusing on the impact of Openclaw and domestic leading companies' performance guidance in the context of the computer industry [1][2]. Key Points - **Openclaw's Role in CPU Demand**: Openclaw, with its core modular distributed architecture and independent persistent memory module, enhances CPU demand by transitioning from passive tools to proactive assistants. Its lightweight deployment can adapt to older computers and low-power devices, stimulating basic CPU demand while high-end applications require multi-core capabilities and high-performance terminals, leading to structural demand growth from low-end to high-end CPUs [1][2]. - **High-End Server CPU Growth**: Haiguang Information is projected to achieve a revenue of 14.376 billion yuan in 2025, marking a year-on-year increase of 56.91%. The net profit attributable to shareholders is expected to reach 2.542 billion yuan, up 31.66%. For Q1 2026, revenue is anticipated to be between 3.91 billion and 4.22 billion yuan, reflecting a year-on-year growth of 62.91% to 75.82% [2]. - **R&D Investment Impact**: The company's significant increase in R&D investment has enhanced product competitiveness, leading to a notable expansion in the market share of high-end processors. This strategy has resulted in substantial revenue growth and continuous improvement in overall performance [3]. Additional Important Information - **Related Companies**: The call mentions several related companies, including Haiguang Information, He Sheng New Materials, and various upstream and downstream players in the CPU and server markets, such as Huazheng New Materials, Zhongke Shuguang, Inspur Information, and Micron [3]. - **Risk Factors**: Potential risks highlighted include slower-than-expected policy progress, lower-than-expected downstream demand, and risks associated with artificial intelligence [4].
