Google confirms Tensor G2 processor still uses Samsung's 5nm process

The new Tensor G2 processor on the new Google Pixel 7 series is still manufactured by Samsung's 5nm manufacturing process, and currently, the industry's most advanced processor is typically manufactured using Samsung and TSMC's 4nm process.

There are rumors that the Tensor G2 is manufactured using Samsung's 4nm process, but this information is wrong. A Google spokesperson provided a response to Android Authority confirming that the processor is manufactured using Samsung's 5nm process:

We built Google Tensor G2 specifically for real-world use cases. Our final architecture, including 5nm, helped us achieve this goal while improving performance and power efficiency. This approach also enables us to add new capabilities while taking a step forward in machine learning with our next-generation TPU and G2.

Therefore, Google confirmed that the Tensor G2 is a 5-nanometer chip. Although Google did not disclose the foundry, it is no surprise that Samsung is the main partner of Google. In addition, according to Samsung's roadmap, it has two 5nm nodes: the 5LPE process used by the original Tensor chips, and a newer 5LPP. However, it is unclear which process the Tensor G2 uses.

Even without confirmation from Google, there is some information that the Tensor G2 processor uses a 5nm process. First of all, the processor doesn't increase the clock speed by a huge amount. The Arm Cortex-X1 core in the Tensor G2 runs at 2.85GHz, which is only 50MHz higher than the original Tensor's 2.80GHz. Also, Google itself doesn't mention the chip's manufacturing process anywhere in its Pixel 7 or Tensor press releases, suggesting it's the same process as the previous generation.
