Samsung has unveiled the Exynos W920, its latest crack at a wearable chipset. The Exynos W920 is the first 5 nm SoC for wearables and supposedly offers a significant improvement in CPU and GPU performance compared to the Exynos 9110.

Samsung unveiling the Exynos W920 is not really much of a surprise, considering that it has already leaked several times. Nonetheless, the smartwatch SoC is now official, just a day ahead of the next Galaxy Unpacked event where the Galaxy Watch 4 and Galaxy Watch 4 Classic should make their debuts. Additionally, Samsung is expected to announce the Galaxy Buds 2, Galaxy Z Fold 3 and Galaxy Z Flip 3, as we have reported previously.

According to Samsung, the Exynos W920 offers up to 20% better CPU performance and 10x the graphical capabilities of its predecessor. The company does not name this predecessor, but we assume it means the Exynos 9110 found in the Galaxy Watch Active 2 and Galaxy Watch 3.

The same press release adds that the W920 is a 5 nm SoC, the first for a smartwatch. By contrast, the Exynos 9110 is a 10 nm chip, while Qualcomm manufacturers the Snapdragon Wear 4100 on a 12 nm process. The 5 nm chip has two ARM Cortex-A55 CPU cores and a Mali-G68 GPU that can operate displays at up to 960 x 540 pixels.

Additionally, the Exynos W920 has a Cortex-M55 co-processor to maximise battery life, and LTE modem and GPS support. It is not a given that all Galaxy Watch 4 series devices will have LTE connectivity, though. The Exynos W920 will, eventually, face competition from the Snapdragon Wear 5100, which is said to feature more powerful Cortex-A73 cores. Qualcomm has not announced anything at the time of writing, however.
