Samsung is ready to roll out the Galaxy Watch 4, and if the numerous leaks over the last three weeks have been any indication, it will be among the best Android smartwatches. We got a good look at the design of the Galaxy Watch 4, and Samsung has now detailed the hardware (opens in new tab) powering the smartwatch.

The Galaxy Watch 4 and Galaxy Watch 4 Classic will be powered by the Exynos W920, a 5nm wearable chipset designed to deliver much better performance while being more efficient. The W920 has two Cortex A55 cores — the same cores you'll find on your phone — and an Arm Mali-G68 GPU, with Samsung noting an uptick of 20% from the CPU and an insane 10x boost in graphics performance. There's also a 4G LTE Cat. 4 modem for cellular connectivity, and built-in GPS.

The W920 is built on a 5nm extreme ultra-violet (EUV) node at Samsung SLSI — just like the flagship Exynos 2100 powering the global Galaxy S21 series — and Samsung says the chipset will be able to handle displays of up to 960 x 540. The W920 also includes a low-power Cortex M55 co-processor that allows for always-on screen without having to power up the main cores.

But what's particularly interesting is that the Exynos W920 is the "smallest package" currently in the wearable market, and that means the System-in-Package containing the cores, power management ICs, RAM, and storage module doesn't take up as much room. With space at a premium on wearables, the W920 allows Samsung to roll out smartwatches with larger batteries or sleeker designs.

The Watch 4 and Watch 4 Classic will be the first showcase of the new Wear OS 3.0 platform that Google has created with Samsung, and both products will be unveiled on August 11.

  • Well, I guess I will need to find a bezel cover that will give me the same look and feel of the Gear S3. Will the bezel even be a physical dial or touch based?
  • You can choose either a physical or capacitive bezel.
  • I'm looking forward to seeing what Samsung has put together. Honestly, it's probably gonna be awesome because the newest 4100 processor (hardware) has been a beast. Now with all the recent software updates/upgrades + Samsung's software input alone, that's the math for some stellar tech!
  • Just ordered the Watch 4 Classic - an upgrade from my Gear S3. Looking forward to it!!!!!
