一文读懂:谷歌TPU芯片采用的OCS技术为何先进?中国光模块厂商持续受益
Mei Ri Jing Ji Xin Wen· 2025-11-27 03:26
谷歌"新王"登场,粉碎AI泡沫论? AI四面楚歌之际,谷歌以"全栈王"的姿态出现,为算力设备投资再续命。谷歌 GEMINI3.0大模型 和 TPU芯片 两 大杀手锏的推出,意义重大。意味着谷歌不仅在推理、多模态和Agent(智能体)平台三条主线上同时实现了代 际式跃迁,而且验证了算力领域的Scaling Law(规模法则)依然有效。 也就是说:AI产业趋势仍然在螺旋式上升,算力投入"随规模提升,模型相应继续上行"的经验规律并未打破,"全 栈式"生态集成也在缩短"资金投入-智能验证-盈利回报"的时间差,而这些正是"AI泡沫论"的核心担忧。 值得一提的是,谷歌第七代TPU芯片采用的OCS技术创新,是成本压缩的关键,价格低至英伟达GPU芯片的1/5, 但在特定场景下拥有更强的推理计算能力,因而也受到Meta等大客户的青睐,又为谷歌带来新的增长极。 OCS先进在哪儿? OCS技术全称(Optical Circuit Switching), 也叫"光学电路交换",不同于传统交换机,这个技术的先进之处在 于:光纤信号进入交换机后,直接光路交换,无需做光电转换。 光网络从传统"连接"功能,向智能"交换"功能演进,有效解决了 ...
