Group 1: Core Insights - Industrial demand for silver is significantly higher than jewelry and silverware, with photovoltaic cells in the solar industry being a major contributor [3] - The introduction of new 800V high-voltage direct current (HVDC) data centers, driven by Nvidia's architecture, is expected to create a substantial increase in long-term silver demand [7][8] - The Silver Institute forecasts a 1% decline in overall silver demand in 2025, but supply is expected to increase by 1.5%, leaving the market undersupplied, which is a bullish indicator for silver prices [5] Group 2: Demand Dynamics - The new data centers are likely to use more silver due to its superior thermal conductivity and oxidation resistance compared to copper, especially at high voltages [7] - Demand for silver in these new data centers is expected to be relatively price-inelastic, meaning significant price increases will be needed to curb demand, indicating strong underlying demand for silver [9] - Net physical investment in silver is crucial, with growth in 2025 despite flat industrial demand, suggesting that investor interest remains strong [11] Group 3: Market Outlook - Current corrections in silver prices are acknowledged, but the fundamentals driven by photovoltaic, electric vehicle, and data center demand remain positive [12] - The anticipated demand from new data centers suggests that investors should consider buying silver during price dips this year [12]

【环球网科技综合报道】2月18日消息，据《金融时报》报道称，英伟达与Meta 宣布达成一项多年期、 价值数十亿美元的芯片采购协议。根据协议，Meta将购买数百万枚英伟达最新一代AI加速芯片，包括 即将推出的"Vera Rubin"系列，并承诺大规模部署英伟达独立中央处理器（CPU）以运行其人工智能模 型。 来源：环球网 尽管谷歌、亚马逊、微软和OpenAI等客户正加速自研芯片以降低对英伟达的依赖，Meta仍选择扩大与 其合作。Meta首席执行官马克·扎克伯格上月表示，公司2026年将在AI基础设施上投入高达1350亿美 元，接近2025年支出的两倍。 值得注意的是，Meta近年来也在积极推进自研AI芯片战略，旨在针对其独特工作负载优化性能并降低 成本。然而，据知情人士透露，相关项目遭遇技术挑战和部署延迟，促使公司继续倚重英伟达的成熟解 决方案。 外媒称，此次交易凸显AI计算重心正从"模型训练"向"推理"阶段转移。英伟达CEO黄仁勋近期调整产品 策略，首次将CPU作为独立产品销售，而非与图形处理器（GPU）集成。这一转变旨在满足科技公司对 高效、低延迟推理能力日益增长的需求。 科技咨询机构Creative St ...
