Samsung Electronics announced its new wearable processor, the Exynos W920. The new processor integrates a LTE modem and is the first in the industry to be built with an advanced 5-nanometer (nm) extreme ultra-violet (EUV) process node, the company said.
The Exynos W920 packs two Arm Cortex-A55 cores for high-performing yet power-efficient processing and an Arm Mali-G68 GPU that boasts improved CPU performance, with 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 and more interactive 3D graphical user interfac on a device’s qHD (960×540) display.
Even with the latest features and enhancements, the Exynos W920 comes in the smallest package currently available in the market for wearables with Fan-Out Panel Level Packaging (FO-PLP), the company said. The technology incorporates the Exynos W920, power management IC (PMIC), LPDDR4 and embedded multimedia card (eMMC) in the same package using System-in-Package-embedded Package on Package (SiP-ePoP) configuration. The processor’s compact size allows smartwatches to house larger batteries or don sleeker designs.
Rather than powering up the main CPU, the W920 activates a dedicated low-power display processor, the Cortex-M55, reducing display power consumption under AOD mode compared to its previous Exynos model, the company said.
For seamless connected experiences on the go, the Exynos W920 is embedded with a 4G Cat.4 modem 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.
