This would be your next Tensor

Last week, almost everything was leaked about the new Tensor G5 chip that will live inside the upcoming Pixel 10 and the Tensor G6 for the Pixel 11. New data has now been leaked from a major leak of the plans of Google’s Tensor chip, which reveal that the tech giant is working on developing a completely custom chip for the Pixel Watch.

If the Tensor G5 is to be the first chip produced entirely by Google without help from Samsung as happened in previous models, it also wants May the next chip in your smartwatches be something special. Especially since, as happened with the SoC of its Pixel devices, the one used by its watches like the Pixel Watch 2 or the Watch 3 comes from Qualcomm with the Snapdragon W5+.

This chip was able to exponentially improve the autonomy of both watches compared to the first Pixel Watch which had a Samsung Exynos in its guts. The change is now accompanied by documents recently leaked by Google’s chip division to Android Authority, in which the first Tensor chip appears for the Pixel Watch.

There are few details about this chip —quite the opposite of the Tensor G5 and G6 whose specifications have been completely disclosed— but yes on its possible launch, which it would be for 2026and thus appear in the bowels of the next Pixel Watch 5. Yes, some data points to a configuration heart composed of one Arm Cortex-A78 core and two Arm-Cortex-A55 cores; although they are not from the last batch.

But At this point there is some good newssince the Snapdragon W5+ used in the current Pixel Watch 3 available in Europe uses an older core, the Cortex-A53 in 4 nm. Better yet, Google’s Tensor chip would be built on the 3nm node, a more advanced technology than Qualcomm’s current offering.

Not all details are known, but this leak points in the right direction so that Google continues to improve the experience of its smart watches which, although they offer a very clean user experience, in terms of autonomy they are still a little far from what we can expect from a smartwatch , at least two or three days.
