HBM4,变贵了
半导体行业观察· 2025-06-11 01:39
Core Viewpoint - Samsung Electronics and SK Hynix are set to increase production costs for the next generation of High Bandwidth Memory (HBM) due to larger core die sizes and outsourcing of base die production, which they may struggle to pass on to customers as Micron begins supplying HBM to Nvidia, breaking SK Hynix's previous monopoly [1][2]. Group 1: Production Changes - The number of I/O interfaces has increased in HBM4, leading to a decrease in the number of chips produced per wafer compared to HBM3E, as the core die size expands [2]. - HBM4 will utilize 10nm fifth-generation DRAM, maintaining the same generation as HBM3E, but with I/O numbers increasing from 1024 to 2048, directly impacting production efficiency [2]. Group 2: Cost Implications - Despite an expected slight increase in wafer output for Samsung's HBM4 due to the use of 10nm sixth-generation DRAM, the overall manufacturing costs are anticipated to be higher due to increased process complexity [3]. - The price for HBM4's 12-layer stacked products is projected to exceed $600, while current HBM3 and HBM3E products are priced around $200 and $300, respectively [3]. Group 3: Outsourcing and Collaboration - The shift to using foundries for producing HBM4's base die is a significant factor in rising costs, as previous generations were produced in-house by memory manufacturers [4]. - Major AI chip companies like Nvidia, AMD, and Microsoft are increasingly demanding customized base die, indicating a trend towards collaboration between memory manufacturers and foundries for advanced HBM products [4].

Core Viewpoint - NXP is planning to close its Nijmegen factory in the Netherlands and three factories in the United States, with the transition expected to take up to ten years as production shifts to new facilities in Dresden and Singapore [1][4]. Group 1: Factory Closures - The closure of the Nijmegen factory, which primarily produces automotive chips, is part of a strategic shift to modernize production capabilities [3][4]. - The new factories in Dresden and Singapore will utilize 12-inch wafer technology, which is expected to double the chip output compared to the current 8-inch wafer production at the Nijmegen and U.S. factories [1][4]. Group 2: Strategic Changes - NXP's strategy has evolved to include joint ventures for the new factories, which will help mitigate risks and reduce fixed and production costs, ultimately improving profit margins [2][4]. - The transition to the new facilities is anticipated to be beneficial for the company's long-term operational efficiency and profitability [2]. Group 3: Workforce and Economic Impact - The Nijmegen factory employs around 1,700 people from over 50 countries and is considered one of the largest semiconductor manufacturing bases in Europe [4]. - The factory has faced challenges due to economic headwinds, leading to a reduction in workforce by 12 employees last year [4].

Core Viewpoint - Apple's macOS will stop supporting Intel chips by 2025, marking the end of a 20-year partnership with Intel, as the company shifts its focus entirely to its own Apple Silicon chips [2][4]. Group 1: Transition from Intel to Apple Silicon - The upcoming macOS 26 Tahoe will be the last version to support Intel chips, as Apple aims to concentrate its innovation on Apple Silicon [2][3]. - Apple began using Intel processors in 2006, with the launch of the MacBook Pro featuring Intel's Core Duo processor, driven by the desire to create the best personal computers [2]. - The transition to Apple Silicon was announced in 2020, with Apple recognizing the superior performance-per-watt of ARM-based hardware compared to Intel's x86 architecture [3][4]. Group 2: Performance and Market Dynamics - The performance-per-watt metric has become crucial in the tech industry, especially with the rise of mobile devices and data centers, leading to a shift in processor design considerations [2]. - By 2021, ARM claimed that "performance per watt is the new Moore's Law," highlighting the competitive edge of ARM architecture over Intel in mobile markets [4]. - Intel's strategic missteps over the past two decades have resulted in a failure to effectively compete in the mobile and GPU markets, leading to significant leadership changes within the company [4]. Group 3: Support Timeline - Apple typically provides security updates for macOS for three years post-release, meaning Intel hardware under macOS 26 Tahoe will receive support until at least the end of 2028 [5].
