A former Google TPU engineer who worked on V7 and V8 revealed how TPU actually competes with Nvidia. The answer isn't about chip specs — it's about system-level design, software co-optimization, and a fundamentally different philosophy. Apple, Anthropic, and Meta are all using TPU now. Here's what that means.

听了一期前谷歌 TPU 工程师的访谈，才明白 TPU 和 GPU 压根不是同一道题，硬放一张表里比参数比不出什么名堂。Apple、Anthropic、Meta 都在用 TPU 了，但这东西想用好，门槛比想象的高。
