Google’s Pixel Watch 5 would possibly get a customized Tensor chip, giving up on Qualcomm as a provider. This is smart since Google can be utilizing Tensor chips for its Pixel smartphones, however apparently the swap will solely occur in 2026, so the Pixel Watch 4 will presumably nonetheless use a Qualcomm SoC.
That stated, the roadmap doc that this leak is predicated on is itself from early 2023, which implies quite a bit may have modified from then and up till now, maintain that in thoughts.

Now, this Tensor chip’s CPU would have one Cortex-A78 core and two Cortex-A55 cores, in line with the identical supply, whereas Google can be exploring RISC-V as a possible different to Arm. These CPU cores are positively historic, with the A55 launching in 2017, however it is a little bit of a development in wearables.
Each Samsung and Qualcomm use older cores of their smartwatch chips – the Snapdragon W5 Gen 1 has Cortex-A53 cores (which launched in 2012), whereas the Exynos W1000 has one Cortex-A78 and 4 Cortex-A55, thus being probably the most just like Google’s supposed design. That makes us assume this wearable Tensor would possibly simply be a tweaked Samsung chip – in the identical approach as all the smartphone Tensor chips to this point have been.
What is not identified is what course of know-how this new Tensor chip will use, however it may very well be 3nm. One other unknown is the modem that shall be used – if it is a Samsung design then an Exynos modem would take advantage of sense (it’s in spite of everything what’s used for Google’s smartphones).
