Core Insights - Tesla has confirmed a landmark partnership with Samsung Electronics to produce its next-generation AI chips, with an initial contract value of $16.5 billion, lasting until the end of 2033 [1][3] - Elon Musk emphasized the strategic importance of this collaboration, stating that the $16.5 billion is merely a minimum threshold, with actual output potentially being several times higher [1][3] Company Summary - The core of this deal revolves around Tesla's anticipated AI6 chip, which will power future vehicle models, the Optimus humanoid robot, and the Robotaxi network [3][4] - Samsung will utilize its cutting-edge manufacturing processes at a new $17 billion fabrication plant in Taylor, Texas, specifically for the production of the AI6 chip [3][6] - The AI6 chip is expected to leverage advanced 2nm process technology, representing a significant leap in performance and efficiency compared to the current AI4 chip, which uses a 7nm process [3][6] Industry Summary - Tesla's strategy of switching between top suppliers for chip production reflects a risk diversification approach, while also posing challenges for supply chain management and technology integration [4][6] - For Samsung, securing the exclusive contract for the AI6 chip is a crucial opportunity to enhance its reputation in high-end AI chip manufacturing and to fill capacity at its new Texas facility [6][7] - The deal is expected to boost Samsung's foundry sales by approximately 10% annually and is seen as a pivotal moment in its competition with TSMC [6][7] - The partnership is influenced by geopolitical factors, with Samsung's investment in Texas being a response to the U.S. CHIPS and Science Act, which incentivizes semiconductor manufacturing in the U.S. [7][8] - Samsung is set to receive up to $4.75 billion in direct subsidies from the CHIPS Act, potentially exceeding $9 billion in total benefits, which will help ensure a stable supply chain for Tesla [7][8]

此外，有消息称英特尔还将停止研发下一代芯片14A的研发工作。业内认为，一旦英特尔放弃14A，将 对美国芯片制造业造成沉重打击，并进一步加剧美国对海外芯片生产业的依赖。 受消息面影响，英特尔25日美股开盘跌8%。 在当天提交的一份监管文件中，英特尔表示，该公司正专注于14A研发工作并寻求大型客户。"如果我 们无法赢得重要的外部客户，也无法实现为英特尔14A工艺寻得重要客户的里程碑式目标，我们可能面 临的局面是：继续研发和制造英特尔14A及其后继前沿节点在经济上的不可行。在这种情况下，我们可 能会暂停或终止对英特尔14A及后续节点的研发工作。" 业内认为，一旦英特尔放弃14A，将对美国芯片制造业造成沉重打击。 美国芯片企业英特尔当地时间7月24日发出警告，将不再推进在德国和波兰的项目，并计划将哥斯达黎 加的封装测试业务整合至越南和马来西亚规模更大的生产基地中，同时进一步放缓俄亥俄州工厂的建设 速度，以确保支出与市场需求保持一致。 接近英特尔人士对第一财经记者表示，"这只是预警最坏的一个结果，并不代表会最后执行，对于英特 尔而言，制程工艺肯定还是全力推进，但不会盲目投入，无序扩张。" 对于产能的收缩，陈立武称："过 ...

在开支削减举措中，英特尔成本高昂的代工部门成为重点。该部门为其他公司生产芯片，目前仍在寻找大客户来支撑业务。数据显示，其 代工业务营收为44亿美元，运营亏损却高达31.7亿美元。基于此，英特尔已取消了计划在德国和波兰建设的晶圆厂项目，并将整合其在越 南和马来西亚的测试和组装业务。同时，公司将放缓在俄亥俄州建设尖端芯片工厂的步伐，具体取决于市场需求以及能否为该工厂争取到 大客户。陈立武在备忘录中直言："过去几年，公司投资过多、过快，而需求不足。在此过程中，我们的工厂布局变得不必要地分散，利用 率也不足。"他还强调，公司即将推出的芯片制造工艺（称为14A）将根据已确认的客户承诺进行打造，"不再有空白支票。每项投资都必须 具有经济意义。" 从业务部门表现来看，英特尔客户端计算部门主要负责销售个人电脑的中央处理器，第二季度销售额为79亿美元，同比下降3%。数据中心 业务部门收入增长了4%，达到39亿美元，该部门包括一些人工智能芯片，但主要为服务器中央处理器。陈立武在备忘录中写道，英特尔希 望重新夺回数据中心芯片的市场份额，并正在寻找该业务的永久领导者。目前，长期竞争对手AMD越来越多地从云客户那里赢得服务器业 务，给 ...

智通财经7月25日电，英特尔首席执行官表示，工厂仍是芯片制造商至关重要的环节，需要有重要的外 部客户来承接其14A工艺的产能。 ...
