The Pixel 6 and Pixel 6 Pro are the first Google phones to come with the company’s in-house Tensor SoC. But according to a recent finding, it appears Google started testing the new SoC on the Pixel 5 first.
XDA Recognized Developer Freak07 has uncovered evidence suggesting that the Mountain View giant was testing a Pixel 5 with a Tensor SoC. While digging through the Pixel 6 source, Freak07 came across kernel device tree files for two variants of the Tensor SoC, internally referred to as gs101. The first one is codenamed gs101-b0, while the second one is gs101-a0. We already know that gs101-b0 is the SoC in the Pixel 6 series, but it’s the first time we’re hearing about the gs101-a0.
Another interesting thing is that there are kernel device tree files for two different silicon variants of the Tensor SoC, which google internally calls gs101.

Further digging by Freak07 shows that the gs101-a0 is related to a Pixel device codenamed Whitefin. I…
