Google’s Pixel Watch 5 might get a custom Tensor chip, giving up on Qualcomm as a supplier. This makes sense since Google is also using Tensor chips for its Pixel smartphones, but interestingly the switch will only happen in 2026, so the Pixel Watch 4 will presumably still use a Qualcomm SoC.<\/p>\n
That said, the roadmap document that this leak is based on is itself from early 2023, which means a lot could have changed from then and up until now, keep that in mind.<\/p>\n
Now, this Tensor chip’s CPU would have one Cortex-A78 core and two Cortex-A55 cores, according to the same source, while Google is also exploring RISC-V as a potential alternative to Arm. Those CPU cores are positively ancient, with the A55 launching in 2017, but this is a bit of a trend in wearables.<\/p>\n Both Samsung and Qualcomm use older cores in their smartwatch chips – the Snapdragon W5 Gen 1 has Cortex-A53 cores (which launched in 2012), while the Exynos W1000 has one Cortex-A78 and four Cortex-A55, thus being the most similar to Google’s intended design. That makes us think this wearable Tensor might just be a tweaked Samsung chip – in the same way as all of the smartphone Tensor chips so far have been.<\/p>\n What isn’t known is what process technology this new Tensor chip will use, but it could be 3nm. Another unknown is the modem that will be used – if this is a Samsung design then an Exynos modem would make the most sense (it is after all what is used for Google’s smartphones).<\/p>\n![\"Google](\"https:\/\/fdn.gsmarena.com\/imgroot\/news\/24\/10\/pixel-watch-5-tensor-soc-rumor\/inline\/-1200\/gsmarena_001.jpg\"\/)
