Not even a day until the presentation of the new Samsung smartwatch Galaxy Watch 4 a Watch 4 Classic the Korean tech giant revealed to the public the new chipset that will power them. It's the Exynos W920 chip that was mentioned in previous leaks and will replace the three-year-old Exynos 9110. Although the new chipset is more energy efficient than its predecessor, it promises much better performance.
The Exynos W920 is manufactured by Samsung's foundry division Samsung Foundry using its latest 5nm process. It has two ARM Cortex-A55 processor cores and an ARM Mali-G68 graphics chip. According to Samsung, the new chipset is 20% faster than the Exynos 9110 in processor tests and should be up to ten times more powerful in graphics tests. The maximum display resolution supported by the GPU is 960 x 540 px.

The Exynos W920 comes in the smallest "packaging" currently available in the flexible electronics segment - FO-PLP (Fan-Out Panel Level Packaging). It includes the chipset itself, a power management chip, LPDDR4 type memory and eMMC type storage. This "packaging" is advantageous in that it allows the smartwatch to use larger batteries.
In addition, the chip also received a specialized Cortex-M55 display processor, which is in charge of the Always-on mode. The processor reduces the overall power consumption of devices that use the Exynos W920. The chipset also has an integrated GNSS (Global Navigation Satellite System) navigation system, 4G LTE modem, Wi-Fi b/g/na Bluetooth 5.0. Of course, it also supports the new operating system Wear OS 3 from the workshop of Samsung and Google.
