Google Confirms Tensor G6 Is Built on TSMC 3nm, Not 2nm

The admission shifts scrutiny from a manufacturing breakthrough to chip design and software as the likelier sources of the Pixel 11’s efficiency and on‑device AI gains.

Overview

  • Google’s vice president of hardware, Peng Yu-chun, confirmed Thursday that the Tensor G6 used across Pixel 11 models is manufactured on TSMC’s 3nm process rather than the rumored 2nm node.
  • Google’s product claims for the G6 include a CPU marketed as delivering 25% faster web browsing and 15% quicker app launches, a 50% boost in TPU compute to run Gemini Nano, an upgraded image signal processor for Night Sight and zoom, and an updated Titan M3 security chip.
  • Independent analysts point out that the G6’s reported power-efficiency gains can be explained by design choices such as removing a CPU core and other architecture tweaks, which can improve battery life at the cost of multicore performance.
  • Pre-launch uncertainty grew because device-info tools like DevCheck and early listings by Android Authority did not show the chip’s lithography, underscoring that vendor statements and supply-chain confirmations are needed to settle node questions.
  • Chipmakers’ production costs and wafer allocation help explain why a lower-volume phone line would stick with an advanced 3nm process instead of 2nm, so consumers should watch independent benchmarks and official tooling updates to judge real-world battery life and speed.
