谷歌的供应链多元化战略
谷歌自2021年推出首款Tensor芯片以来，一直依赖台积电的先进制程进行生产。然而，地缘政治风险和供应链集中度过高的隐忧，促使谷歌寻求替代方案。三星作为全球第二大晶圆代工厂商，拥有成熟的GAA（Gate-All-Around）晶体管技术，其2纳米制程已进入试产阶段。
据半导体行业研究机构TechInsights的数据，三星2纳米制程的晶体管密度达到每平方毫米2.5亿个，较3纳米制程提升35%。在功耗方面，同等性能下可降低25%的能耗。这些技术指标使其成为台积电2纳米制程的有力竞争者。
三星代工业务的翻身仗
对三星而言，获得谷歌订单意义重大。近年来，三星在先进制程竞争中落后于台积电，市场份额从2020年的18%下降至2025年的12%。良率问题是三星面临的主要挑战，其3纳米制程的良率一度仅为50%左右，远低于台积电的80%以上。
为扭转局面，三星投入超过200亿美元升级平泽工厂的生产线，并引入ASML最新的High-NA EUV光刻机。据三星透露，其2纳米制程的良率已提升至70%以上，接近量产标准。若能成功拿下谷歌订单，将为其吸引更多客户提供背书。
Tensor G6芯片的技术规格
根据泄露的技术文档，Tensor G6芯片将采用三星2纳米GAA制程，集成超过200亿个晶体管。CPU部分采用ARM最新的Cortex-X6核心架构，GPU则升级至Mali-G920。最引人注目的是其AI处理单元，算力达到45 TOPS，较上一代提升60%。
这款芯片将首先应用于Pixel 11系列手机，预计2027年第一季度发布。谷歌还计划将Tensor G6应用于其云计算服务器的AI推理任务，进一步拓展芯片的应用场景。
台积电的应对策略
面对谷歌可能转单三星的消息，台积电迅速做出回应。台积电董事长刘德音在投资者会议上表示，公司与谷歌的合作关系稳固，双方在下一代制程技术上保持密切沟通。台积电还强调，其2纳米制程将在2026年第四季度量产，良率和性能均领先业界。
为巩固客户关系，台积电推出了"供应链保障计划"，承诺为重要客户提供优先产能分配和价格优惠。此外，台积电正在美国亚利桑那州建设第三座晶圆厂，以满足客户对地缘多元化的需求。
半导体行业的新变局
谷歌与三星的合作若成行，将对全球半导体代工格局产生深远影响。目前，台积电以60%的市场份额占据绝对主导地位，三星位居第二。谷歌作为全球科技巨头，其芯片订单的流向具有风向标意义，可能引发其他大客户重新评估供应链策略。
摩根士丹利半导体分析师查理·陈指出，半导体行业正在从"一超多强"向"双雄争霸"演变。随着AI芯片需求的爆发式增长，先进制程的产能将更加稀缺，客户多元化供应链将成为行业趋势。
Google's Supply Chain Diversification Strategy
Since launching its first Tensor chip in 2021, Google has relied on TSMC's advanced processes for production. However, geopolitical risks and concerns about supply chain concentration have prompted Google to seek alternatives. Samsung, as the world's second-largest foundry, possesses mature GAA (Gate-All-Around) transistor technology, with its 2nm process already entering the trial production phase.
According to semiconductor industry research firm TechInsights, Samsung's 2nm process achieves a transistor density of 250 million per square millimeter, a 35% improvement over the 3nm process. In terms of power consumption, it can reduce energy use by 25% at equivalent performance levels. These technical specifications make it a strong competitor to TSMC's 2nm process.
Samsung Foundry's Comeback Battle
For Samsung, securing Google's orders is highly significant. In recent years, Samsung has fallen behind TSMC in advanced process competition, with its market share declining from 18% in 2020 to 12% in 2025. Yield issues have been Samsung's main challenge, with its 3nm process yield rate once at only about 50%, far below TSMC's 80% or higher.
To turn the situation around, Samsung has invested over $20 billion to upgrade its Pyeongtaek factory production lines and introduced ASML's latest High-NA EUV lithography machines. Samsung reports that its 2nm process yield rate has improved to over 70%, approaching mass production standards. Successfully securing Google's orders would serve as endorsement for attracting more customers.
Technical Specifications of Tensor G6
According to leaked technical documents, the Tensor G6 chip will use Samsung's 2nm GAA process, integrating over 20 billion transistors. The CPU portion adopts ARM's latest Cortex-X6 core architecture, while the GPU is upgraded to Mali-G920. Most notably, its AI processing unit delivers 45 TOPS of computing power, a 60% improvement over the previous generation.
This chip will first be featured in the Pixel 11 series smartphones, expected to launch in Q1 2027. Google also plans to apply Tensor G6 to AI inference tasks in its cloud computing servers, further expanding the chip's application scenarios.
TSMC's Response Strategy
Faced with the news that Google might switch orders to Samsung, TSMC quickly responded. TSMC Chairman Mark Liu stated at an investor conference that the company's partnership with Google remains solid, with both parties maintaining close communication on next-generation process technologies. TSMC also emphasized that its 2nm process will enter mass production in Q4 2026, leading the industry in both yield and performance.
To consolidate customer relationships, TSMC launched a "Supply Chain Assurance Program," promising priority capacity allocation and pricing advantages for key customers. Additionally, TSMC is building a third wafer fab in Arizona, USA, to meet customer demands for geopolitical diversification.
New Dynamics in the Semiconductor Industry
If Google's partnership with Samsung materializes, it will have profound implications for the global semiconductor foundry landscape. Currently, TSMC dominates with a 60% market share, with Samsung in second place. As a global tech giant, Google's chip order direction serves as a bellwether that could trigger other major customers to reassess their supply chain strategies.
Morgan Stanley semiconductor analyst Charlie Chan notes that the semiconductor industry is evolving from "one dominant player with several competitors" to "two titans competing." With the explosive growth in AI chip demand, advanced process capacity will become even scarcer, and customer supply chain diversification will become an industry trend.
