The upcoming Google Pixel Watch 4 is shaping up to be a serious upgrade, especially in the AI department.
While it’s expected to keep the Snapdragon W5 Gen 1 chipset, the real leap lies in its rumored new co-processor – the Cortex-M55.
This new chip, which replaces the aging Cortex-M33 used in previous models, is designed with next-gen AI tasks in mind. According to a report from Android Headlines, the M55 is capable of handling up to five times more AI workloads while consuming far less power. That’s a game-changer for wearables.
Arm introduced the Cortex-M55 in 2020 as its most AI-ready Cortex-M processor. It brings power-efficient digital signal processing (DSP) and machine learning (ML) to the table – all without blowing up the power budget, which is crucial for smartwatches.
Alongside the AI boost, the Pixel Watch 4 is expected to come with 2GB RAM and 32GB storage, staying consistent with previous versions. However, another highlight is the display. Rumors point to a peak brightness of 3,000 nits, a big jump from the Pixel Watch 3’s 2,000 nits. That would put it in the same league as the Apple Watch Ultra 2 and Samsung’s Galaxy Watch 8.
The battery life is also rumored to get a solid bump. The 41mm model might reach 30 hours with always-on display (AOD) and up to 48 hours on Battery Saver. The 45mm version could stretch even further – 40 hours with AOD and 72 hours with Battery Saver mode.
While the main processor remains the same, Google’s possible focus on smarter AI, improved screen clarity, and longer battery life makes this refresh more exciting than it seems at first glance. Especially when paired with the rumored integration of Gemini AI, the Pixel Watch 4 could be a strong contender in the smartwatch race.
Expect to see the Pixel Watch 4 unveiled during the Made by Google event on August 20, alongside the Pixel 10 lineup. If leaks are accurate, all devices – including the Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL, Pixel 10 Pro Fold, and the new smartwatch – will go on sale starting August 28.
