IT之家 2 月 7 日消息，据彭博社 2 月 6 日报道，在 AI 浪潮和芯片应用全面渗透经济体系的推动下，全 球半导体行业今年的营收将历史性地突破 1 万亿美元（IT之家注：现汇率约合 6.95 万亿元人民币）。 诺伊弗表示，半导体行业仍将保持周期性波动的特征，但长期向上的发展趋势已经确立。"波动会一直 存在，整体市场蛋糕正在持续变大。" 在行业前景方面，英伟达首席执行官黄仁勋周五表示，围绕数据中心和 AI 基础设施的投入具备可持续 性，并不认同市场对过度投资的担忧。 随着新一代数据中心对计算能力的需求激增，英伟达、美光等芯片厂商迎来强劲增长，推动整个行业持 续超出此前的增长预测。诺伊弗指出，外界原本预计行业至少还需要 4 年才能迈过 1 万亿美元门槛。 从细分领域来看，作为设备核心的逻辑芯片在 2025 年营收增长 40%，达到 3019 亿美元；用于数据存 储和管理的存储芯片销售额增长 35%，达到 2231 亿美元。地区层面，中国、亚太、美洲、欧洲市场均 实现增长，只有日本出现下滑。 半导体行业协会数据显示，2025 年行业销售额为 7917 亿美元（现汇率约合 5.5 万亿元人民币），预计 202 ...

三星电子、SK海力士和美光科技等存储芯片巨头开始推行一种前所未有的合约框架：从传统的长期固 定价格协议转向短期甚至月度合同，并引入"价格追溯结算"机制，市场主导权已明显向供应商倾斜。 据韩国科技媒体etnews报道，这些制造商近期与北美大型科技客户签署的新型供应合约中，已允许在合 约期结束后根据市场价格进行付款调整。该变化主要针对迫切希望确保AI基础设施芯片供应的客户群 体，反映出在当前需求驱动下，保障供应已成为许多客户比控制价格更优先的考量。 市场有风险，投资需谨慎。本文不构成个人投资建议，也未考虑到个别用户特殊的投资目标、财务状况或需要。用户应考虑本文中的任何 意见、观点或结论是否符合其特定状况。据此投资，责任自负。 传统内存芯片供应合约通常采用固定价格模式，即使在市场波动下，年度内价格调整幅度一般不超过 10%。例如，若DRAM合约价定为100元，通常在一年内保持稳定，仅在季度协商中进行微调，浮动范 围一般在90元至110元之间。 新型合约模式已转向价格追溯补偿机制。假设以100元价格签订一年期DRAM供应合约，若到期时市场 价格上涨100%，客户需额外支付100元差价。目前三星、SK海力士和美光三大存 ...

公众号记得加星标⭐️，第一时间看推送不会错过。 众所周知，个人电脑（PC）主系统内存——正式名称为随机存取存储器，简称 RAM——的价格已经 失控。在过去的几个月里，DDR5 RAM（最新标准）模组的价格一路飙升，翻了一倍甚至更多。一 套 64GB 的台式机内存套件迅速变得比索尼 PlayStation 5 还要昂贵，而一些更大容量的套件现在的 价格甚至超过了高端台式机 GPU。这种疯狂的价格上涨也开始蔓延到较旧的内存类型，比如 DDR4 和 DDR3。 这些价格上涨将影响每一个依赖内存或存储的产品——但我现在想专注于笔记本电脑。笔记本电脑使 用的物理模组与台式机不同，但底层的内存颗粒是相同的，且容易受到相同的价格压力影响。作为 PCMag 领先的笔记本电脑专家之一，我可以告诉你：对于今年需要新电脑的人来说，情况即将变得 困难。 此外，这种供应短缺正在影响其他将内存作为整体一部分的组件。最直接的连锁反应将冲击显卡，显 卡依赖专用显存来辅助图形渲染和本地 AI 工作流。（撇开内存紧缺不谈，显卡本身的需求也在大幅 增加。）这些显卡所使用的 GDDR6 和 GDDR7 显存价格也因同样的原因上涨：每 Gb 的成本在 ...
