- 据中金在线报道,谷歌发布第七代TPU Ironwood,单芯片峰值算力达4614 TFLOPS,支持9216芯片集群,总算力42.5 ExaFLOPS,计划2025年出货150-200万片[3]。
- 研究显示,NVIDIA在数据中心GPU市场占92%份额,CUDA生态绑定数百万开发者,形成核心壁垒,但面临客户集中度过高(前四大客户贡献超40%收入)风险[4]。
- 谷歌TPU面临软件生态局限(仅支持JAX/TensorFlow)和部署限制(仅通过Google Cloud提供),迁移成本高[3]。
- Reddit用户讨论:看好算力供应链,如光模块Lumentum(LITE)、国内旭创/胜宏,提及NAND闪存和能源基建机会[5]。
- 雪球用户“古董鱼”认为:谷歌TPU虽强,但封闭技术栈(不支持CUDA)和缺乏全球供应链,难以颠覆NVIDIA;Anthropic签百万TPU协议验证需求,但谷歌仍大量采购NVIDIA GPU[1]。
研究与社交媒体一致认为,NVIDIA的CUDA生态是其核心护城河,短期内难以被突破;谷歌TPU在性能和能效上有优势,但生态和部署限制制约其广泛应用。投资方面,供应链(光模块、NAND)和能源基建(如储能、电力)是共同关注的机会点。NVIDIA需应对ASIC芯片竞争和客户集中度风险,而谷歌需扩展TPU生态以提升市场份额。
