Samsung Electronics is offering a new processor for wearables, the Exynos W920. The new processor integrates an LTE modem and is built with an advanced 5-nanometer (nm) extreme ultraviolet process node, offering powerful yet efficient performance demanded by next-generation wearable devices.

The Exynos W920 is embedded with a GNSS L1 receiver (GPS, GLONASS, Beidou, Galileo) for tracking speed, distance and elevation during outdoor activities. It also has a 4G LTE Cat. 4 modem.

“Wearables like smartwatches are no longer just a cool gadget to have. They’re now a growing part of our lifestyles to keep you fit, safe and alert,” said Harry Cho, vice president of System LSI marketing at Samsung Electronics. “With the Exynos W920, future wearables will be able to run applications with visually appealing user interfaces and more responsive user experiences while keeping you connected on the go with fast LTE.”

The Exynos W920 has two Arm Cortex-A55 cores for high-performing, power-efficient processing and an Arm Mali-G68 GPU with CPU performance improved by 20 percent and 10 times better graphics performance than its predecessor. With upgraded cores and improved performance, the Exynos W920 enables faster application launches and more interactive, eye-catching 3D graphical user interface (GUI) on a device’s qHD (960×540) display.

The Exynos W920 comes in a tiny package with Fan-Out Panel Level Packaging (FO-PLP). The technology incorporates the Exynos W920, power management IC and embedded multimedia card. The processor’s compact size allows smartwatches to house larger batteries or have sleeker designs.

Always-on-display (AOD) for wearables, especially for smartwatches, is a widely adopted feature as it makes it effortless to take a quick look at the time, notifications, missed calls and more without the need to wake the watch up from sleep mode. 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 Exynos W920 supports a new unified wearable platform Samsung built jointly with Google, and will be first applied to the upcoming Galaxy Watch model.
