公众号记得加星标⭐️,第一时间看推送不会错过。 来源 : 内容来自tomshardware 。 英伟达的 DGX Cloud,曾被定位为面向企业的直连式 AI 云服务,如今在公司战略中悄然退居二线。据 The Information 援引内部人士消息称,这 一 GPU 云平台目前大部分算力已用于英伟达自身的研究,而非继续作为面向客户的核心产品。 在英伟达 2026 财年第二季度财报中,公司已不再将数十亿美元的云支出承诺归因于 DGX Cloud,而此前的财报中这一项目曾被重点披露。虽然 DGX Cloud 仍然出现在收入分类里,但其角色显然已经转向"内部基础设施",而不是正面迎战微软 Azure 或 AWS。换句话说,DGX Cloud 依然 存在,但已不再是市场竞争的前锋。 DGX Cloud 的兴衰 DGX Cloud 于 2023 年推出,当时的定价为每月每个 H100 实例 36,999 美元。在 GPU 严重短缺的背景下,这样的高价还算合理,但随着供应逐 步改善,这种"紧缺替代方案"的价值已大幅下降。如今,AWS 已将 H100 与 A100 的租赁价格削减高达 45%,这让 DGX Cloud 的 ...

半导体行业观察· 2025-09-13 02:48
Core Viewpoint - The Intel 1103 chip was the first commercially successful DRAM chip, marking a significant advancement in semiconductor memory over magnetic core memory in terms of price, density, and logical compatibility [1][2]. Group 1: Historical Context - The Intel 1103 was launched in October 1970, aiming to match and surpass the performance and cost of magnetic core memory, which was prevalent at the time [1]. - By 1971, the 1103 became the best-selling semiconductor memory chip globally, adopted by 14 out of 18 major computer manufacturers within two years [2]. Group 2: Technical Specifications - The 1103 chip encapsulated 1024 bits of data in an 18-pin dual in-line package, utilizing p-MOS technology with an 8-micron silicon gate process [4]. - It featured a 32×32 bit internal array, requiring a refresh of all memory every 2 milliseconds, with many designers employing burst refresh strategies [6]. Group 3: Market Impact and Adoption - Despite its technical limitations, the economic advantages of the 1103 led to its widespread adoption, with major systems like HP's 9800 series and DEC's PDP-11 utilizing it as primary memory [10]. - The introduction of the 1103A variant improved timing margins and reduced power consumption, further facilitating its integration into various systems [10]. Group 4: Legacy and Influence - The Intel 1103 established a foundation for future DRAM technologies, paving the way for single-transistor DRAM and influencing the development patterns of DRAM that persist today [13]. - It serves as a reminder that disruptive designs do not always need to be the most elegant, emphasizing the importance of system-level economics over transistor-level perfection [13].
一桩收购,成就甲骨文
半导体行业观察· 2025-09-13 02:48
2009 年 4 月,甲骨文公司(Oracle Corp.)做了一桩在当时看来并不划算的买卖。至少按照当时的普遍看法是如此。公司宣布以 74 亿美元收购 Sun Microsystems(扣除 Sun 的现金和债务后净额 56 亿美元)。 简而言之,当时外界对甲骨文首席执行官拉里·埃里森(Larry Ellison,见图)的判断是:为什么一家数据库和企业软件公司要收购一家正在衰落的 服务器公司,还要承担硬件业务带来的成本负担? 公众号记得加星标⭐️,第一时间看推送不会错过。 来源 : 内容来自siliconangle 。 甲骨文首席执行官拉里·埃里森(Larry Ellison) 那么,这一切和 Sun 有什么关系?如前所述,收购 Sun 带来的是系统能力,而非单纯的服务器。虽然 Exadata 在收购前就已存在,但此前运行在 HP 硬件上。收购后,甲骨文掌握了软硬件两端,很快将 Exadata 的宣传语定为"工程化系统":即为硬件而设计的软件,反之亦然。 这种专长在甲骨文进军云计算时派上了用场。2008 年甲骨文 OpenWorld 的主题演讲中,埃里森还曾把云业务斥为"胡言乱语"。但几年后,甲骨文 不得不 ...
