Samsung released the world’s first 5nm process wearable chip Exynos W920
Samsung announced the launch of a new wearable chip Exynos W920, which is the industry’s first similar product manufactured using a 5nm extreme ultraviolet lithography (EUV) process. Exynos W920 also integrates an LTE modem, which can provide powerful and efficient performance for next-generation wearable devices. Samsung said that wearable devices like smartwatches are no longer just cool tools, they will gradually become part of people’s daily lives.

Exynos W920 contains two Arm Cortex-A55 cores, which are efficient and energy-saving, and its CPU performance is about 20% higher than the previous generation. GPU is Arm Mali -G68, graphics performance improved by 10 times. Samsung said that the upgraded kernel and improved design can launch applications faster on a display with a resolution of 960×540 and provide a better user exchange interface. Exynos W920 is embedded with a 4G LTE Cat.4 modem and Global Navigation Satellite System (GNSS) L1, which can track parameters such as speed, distance, and altitude during outdoor activities.
Although it has stronger performance and more functions, Exynos W920 uses the smallest fan-out panel-level package (FO-PLP) in wearable devices on the market, which also includes a power management IC (PMIC), LPDDR4 memory, and eMMC storage. The compact size can allow devices such as smart watches to accommodate larger battery capacity, and can also provide a more stylish design.
For wearable devices, AoD (always-on display) is an important function, such as smartwatches, which can check the time, notifications, and missed calls at any time. Exynos W920 is responsible for activating the Cortex-M55 chip dedicated to low-power display instead of the main CPU, which can effectively reduce power consumption.
