智通财经APP获悉，据知情人士透露，Meta Platforms(META.US)在内部研发AI芯片过程中遭遇挑战， 已放弃使用其最先进的芯片方案，转而采用设计更简化的版本。上周，由于芯片设计环节出现技术困 难，该公司正式终止了正在研发的最先进AI模型训练芯片项目。报道还指出，Meta已于上周向人工智 能基础设施部门员工同步了这一技术路线调整的最新计划。 Meta放弃自研芯片的决定，揭示了各公司在试图设计能与市场霸主英伟达(NVDA.US)抗衡的AI芯片 时，所面临的普遍困境。 一位参与Meta芯片研发的内部人士透露，公司内部对开发能与英伟达芯片性能匹敌的计划普遍持谨慎 态度，主要担忧在于项目存在延期或需要重新设计的风险。该人士指出，相关报告显示，这类芯片的研 发需要组建大规模工程师团队，负责芯片设计、调试及功耗控制等关键环节。若无法有效解决功耗问 题，这些自研芯片在与英伟达成熟产品的对比中可能不具备投入使用的价值。 Iris训练芯片采用单指令多数据(SIMD)计算架构。该架构对硬件工程师而言设计门槛较低，但软件工程 师在训练AI模型时面临显著编程挑战。据报告披露，Olympus采用与英伟达AI芯片同源的单指 ...

智通财经APP注意到，英伟达(NVDA.US)在周三公布远超预期的业绩后，成为市场上最具增长潜力的股票之一。然而，其交易价格为何看起来像一只价值 股？ 这家芯片巨头的股价周四下跌 5.5%，创下 4 月 16 日以来的最大单日跌幅，并拖累标准普尔 500 指数一同走低。目前该股的价格约为预期收益的 22 倍，远 低于其 37 倍的五年平均水平，且仅略高于标普 500 指数的平均估值倍数。 由于分析师基于英伟达第一季度营收预期达到780亿美元（远超华尔街此前约730亿美元的共识预期）而纷纷上调盈利预测，这个市盈率数字预计将进一步下 降。 "如此强劲的业绩与股价表现乏力之间存在某种脱节，"持有英伟达股票的 Dakota Wealth Management 高级投资组合经理罗伯特·帕夫利克表示。"你当然会认 为在这样的财报之后它会表现良好。公司展现出了非常强劲的增长。" 数据显示，英伟达现在的市盈率比标普 500 指数中约三分之一的股票都要便宜，但其过去 12 个月 65% 的营收增长率在该指数中排名第三。相比之下， Palantir 的营收扩张排名标普 500 第四，而其股价交易倍数约为预期收益的 98 倍。 M ...
