未知机构：美银将2026年TPU出货预期从400万颗上修至460万颗看好-20260224

Summary of Conference Call Notes Industry Overview - The focus is on the demand for Tensor Processing Units (TPUs) and the related supply chain, particularly in the semiconductor industry, with a specific emphasis on companies in Taiwan [1][2][3]. Key Points and Arguments - TPU Shipment Forecast: Bank of America has revised its 2026 TPU shipment forecast from 4 million units to 4.6 million units, indicating a strong demand for TPUs, which is expected to double from last year's shipments of 2.3 million units [1][2][3]. - Supply Chain Companies: The report highlights optimism for several companies in the supply chain, including: - TSMC (2330) - King Yuan Electronics (2449) - ASE Technology Holding (3711) - Chroma ATE (2360) - Wistron NeWeb Corporation (6515) - Winbond Electronics (6223) - Siliconware Precision Industries (3661) [3]. - Market Drivers: The strong demand for TPUs is attributed to rapid growth in workload requirements and external sales, particularly influenced by changes in management at Meta's MTIAASIC project [3]. - Google's Strategy: Google is accelerating the adoption of its self-developed ARM server CPUs, currently known as Axion, which are expected to replace x86 CPUs in conjunction with TPUs by the second half of 2027 [3]. Additional Important Insights - Amazon Trainium Demand: Bank of America has also increased its forecast for Amazon's Trainium demand, raising the 2026 estimate from 2 million units to 2.1 million units and the 2027 estimate from 2.6 million units to 3 million units. This is due to Amazon's capital expenditures being heavily focused on AWS investments, which accounted for 74% of total capital expenditures in 2025, up from 25% in 2020 [4]. - COWOS Wafer Consumption: The demand for COWOS-S wafers has been increased by 7% for 2026-2027 due to the strengthened TPU demand. Additionally, COWOS-R wafer consumption is expected to rise by 1% driven by the production ramp-up of AWS Trainium3 [4]. - Positive Outlook for ASIC Growth: Bank of America maintains a positive outlook on ASIC growth, which is expected to benefit manufacturers like TSMC [4]. - Earnings Estimates Adjustments: The bank has raised the estimated earnings per share (EPS) for Siliconware Precision Industries for this year and next, increasing the target price from NT$4,150 to NT$4,700. Similarly, King Yuan Electronics' EPS estimates have been raised, with the target price adjusted from NT$335 to NT$350 [4].
