Google did not divulge the Pixel Watch specifications during its I/O keynote, meaning that a lot of information was going to arrive through external sources. The latest rumor claims that Google’s wearable will not only feature a co-processor to offset the load on the primary SoC, but it could arrive with the most amount of RAM seen on a Wear OS wearable.

An unnamed source informed 9to5Google that in addition to featuring the Exynos 9110 underneath the hood, the Pixel Watch is said to arrive with a co-processor. The existence of the co-processor would likely be to handle the less intensive tasks so the primary chipset would have more breathing room to tackle the more taxing operations, resulting in a smoother Wear OS experience.
