Samsung Exynos W920 5nm chipset for wearables announced, to power Galaxy Watch 4 series

Samsung has unveiled its Exynos W920 chip for next generation wearables. It is the first chip in the industry to be built with 5nm process node.


  • Samsung has announced the new Exynos W920 chip for wearables
  • The Exynos W920 will power the Galaxy Watch4 series
  • The new chip is built with a 5nm EUV process node

Samsung, just a day ahead of its Unpacked Event, today announced its new wearable processor, the Exynos W920. The new integrates an modem. It is the first in the industry to be built with an 5-nanometer (nm) extreme ultra-violet (EUV) process node.

The new will provide “powerful yet efficient performance demanded by next-generation” wearable devices. The Exynos W920 packs two ARM Cortex-A55 cores for high-performance and an ARM Mali-G68 GPU. This results in an improved performance of around 20-percent and ten times better graphics performance than its predecessor.

With upgraded cores and improved performance, the Exynos W920 enables faster application launches. Furthermore, it allows for more interactive 3D graphical user interface (GUI) on a device’s QHD (960×540) display. The Exynos W920 comes in the smallest package currently available in the market for wearables. It comes with Fan-Out Panel Level Packaging (FO-PLP).

The technology incorporates the Exynos W920, power management IC (PMIC), LPDDR4 and embedded multimedia card (eMMC) in the same package. This is done using System-in-Package-embedded Package on Package (SiP-ePoP) configuration. The processor’s compact size allows smartwatches to house larger batteries.

Samsung has also done optimizations on the chip for better Always-on display performance of the watch. Rather than powering up the main CPU, the W920 activates a dedicated low-power display processor, the Cortex-M55. This reduces display power consumption under AOD mode compared to its previous Exynos model.

Exynos W920 is embedded with a LTE Cat.4 as well as a Global Navigation Satellite System (GNSS) L1 for tracking speed, distance and elevation during outdoor activities. The Exynos W920 supports a new unified wearable platform Samsung built jointly with Google, and will be first applied to the upcoming Galaxy Watch model. The Galaxy Watch 4 series from Samsung has already leaked extensively in the past.
