    数据中心CPU收入增长35%,Yole报告揭示网络芯片扩张

    Yole Group数据显示,2026年第二季度数据中心CPU收入达132亿美元,环比增长34.9%,增速超过AI ASIC(+23%)和GPU(+13%)。数据中心网络芯片市场2026年将达530亿美元,其中AI工作负载占约88%收入,纵向扩展交换机销量同比增长94%。AMD CEO苏姿丰称2026年为“AI推理元年”,预计到2030年数据中心AI加速器市场规模接近1.5万亿美元,CPU市场复合年均增长率约50%。

    增长最快的交换机细分市场:2026 年的销量比 2025 年增长 94%,随后收入将以每年 59% 的速度增长,到 2031 年达到 420 亿美元,其中共封装光技术占比 23%。 Yole表示,在人工智能集群中,数据传输的支出占比增长速度超过了计算支出占比。互连不再是数据中心预算中的辅助项目,而是成为了主要支出项目之一。 美国公司主导着这个充满活力的市场。NVIDIA在2025年和2026年位居全球第一大网络ASIC供应商,它率先推出了基于交换机的纵向扩展架构,并且是高性能AI千兆集群横向扩展的关键参与者。 从2026年起,博通、思科、Marvell、Astera Labs和华为等公司将占据重要地位,尤其是在AMD MI400 GPU方面。与此同时,AWS、Meta和微软等超大规模数据中心运营商也在开发各自的AI ASIC芯片。谷歌的TPU则独立于传统的纵向扩展和横向扩展框架,采用环形拓扑结构进行点对点连接,而非通过数据包交换机。 Yole表示,长期以来一直是 NVIDIA 优势的纵向扩展交换技术,随着开放标准的出现,为超大规模数据中心提供了一个可靠的替代方案,这一技术正在向 NVI

    Skild AI 用自对弈让机器人学会物理技能

    CoreWeave 投资人解释这家亏损的 AI「新云」厂商如何摆脱债务

    Hugging Face 发布 Beam:501B 开源模型,支持 1M 上下文与自托管

    Hugging Face 发布 Beam,一个 501B 参数的稀疏 MoE 开源模型,面向 1M 上下文的长文本推理与智能体任务,每个 token 仅激活约 23B 参数。模型采用 52 层混合注意力,43 层为 512 token 滑动窗口、9 层为全局注意力,KV cache 每 token 增长 36 KiB,约为全注意力方案的六分之一。官方提供 BF16、FP8 和 NVFP4 三种 checkpoint,NVFP4 可将权重从约 1 TB 压缩到约 280 GB,并已获 transformers、vLLM 和 SGLang 的 day-0 支持。

    家输出用归一化的路由器权重组合,并缩放 2.5 倍。 每个 token 只运行 8 个专家,因此模型用约 23B 参数计算每个 token。所有 256 个专家都保留在内存中,因此部署需要 501B 模型的内存,但以 23B 模型的速度运行。BF16 checkpoint 以 safetensors 格式约为 1 TB。NVFP4 checkpoint 为 NVIDIA Blackwell GPU 以 4 位精度存储大多数参数,部分参数保留为 BF16 以保证准确性。Hub 上还有 FP8 checkpoint,非常适合 Hopper 和 Ampere 系列芯片。 如果你想自己部署 Beam,请查看下面的 vLLM 或 SGLang 配方。 残差流 残差连接是最独特的部分。标准 transformer 以权重 1 将每个子层输出加到流中,因此流随深度增长。 Beam 将输入嵌入计为第 1 步。在第 k 步,它以权重 1/sqrt(k) 加上子层输出,并以权重 sqrt((k-1)/k) 保留现有流。两个权重的平方和为 1,因此流从第一层到最后一层保持恒定尺度。在所有 104 次加法之后
