Samsung has officially announced the Exynos W920, a new soc for the upcoming Galaxy Watch 4 and other wearables. The soc is equipped with a 4G modem and is the first wearables soc made on a 5nm node.
In a news release, Samsung writes that the Exynos W920 contains two Arm Cortex-A55 cores and an Arm Mali-G68 GPU, which should provide a significant improvement over the previous generation soc for wearables, the Exynos 9110. -performance should be 20 percent better and the GPU performance ten times better, according to Samsung. In addition, the soc is equipped with a 4G LTE-Cat 4 modem and GNSS.
