TSMC(US:TSM) 傅里叶的猫·2026-01-15 15:58Group 1 - The AI hardware sector has seen a resurgence due to two main factors: Goldman Sachs' strategy meeting indicating a demand of 25 million units for 1.6T optical modules and 70 million units for 800G optical modules by 2026, and TSMC's fourth-quarter earnings report showing a 35% year-over-year profit increase, exceeding expectations and marking the eighth consecutive quarter of profit growth [1][2]. - TSMC's projected capital expenditure for 2026 is between $52 billion and $56 billion, following a total capital expenditure of $40.9 billion in 2025 [1]. - Macquarie's report highlights a constraint in the DRAM industry, stating that new capacity in the next two years can only support approximately 15GW of AI data center construction, which may lead to delays and reshuffling in global AI expansion plans [2]. Group 2 - Major companies provide core suppliers with demand and share guidance for the following year in November-December, allowing suppliers to prepare inventory. Optical modules are essential components for AI computing servers, and changes in their demand can reflect the overall demand for data centers [4]. - The anticipated demand for 800G and 1.6T optical modules is expected to remain strong, particularly for overseas computing needs, which serves as a response to Macquarie's report [4]. - Concerns regarding overseas computing demand for 2026-2027 have been alleviated by recent events, potentially leading to upward revisions in order expectations for liquid cooling manufacturers [5]. Group 3 - Updates in the liquid cooling industry include NV utilizing microchannel cold plate technology, with samples sent to a leading company [7]. - Google is expected to place orders exceeding $1 billion with a mainland liquid cooling leader in 2026, significantly higher than the previous expectation of $500-600 million [13]. - A whitelist for NV liquid cooling-cold plates may include names of certain mainland listed companies by March [13].
