Snapdragon Wear 4100 Platform

Qualcomm has unveiled the new Snapdragon Wear 4100 platforms, Snapdragon Wear 4100+ and Snapdragon Wear 4100, designed for next-generation connected smartwatches. These are based on our ultra-low-power hybrid architecture.

The Snapdragon Wear 4100+ architecture includes:

  • A high-performance SoC with improved CPU, GPU, Memory, Cellular Modem, and camera sub-systems in 12nm low power process with dual dedicated DSPs for modem/location and sensors/audio
  • An AON ultra-low power co-processor for offloading a series of use cases including display, sensors, maps, and time
  • A stronger AON software interface to manage the interactions between the SOC and the co-processor.

Basically, Snapdragon Wear 4100+ is a big processor with the small co processor and the Wear 4100 is just a big processor.

Qualcomm says that the Snapdragon Wear 4100+ architecture is engineered to deliver significant improvements in performance, connectivity, smartness, and power. Key highlights of the platforms include:

Snapdragon Wear 4100 Platform

Super-Fast Performance and Connectivity: The SoC comprises of quad-core A53 processors, Qualcomm Adreno 504 class graphics processing, faster LPDDR3 memory (750MHz), and dual ISPs with support for up to16 megapixel cameras. Snapdragon Wear 4100+ is designed to deliver more than 85% faster performance, compared to Snapdragon Wear 3100 platform, and enhances the overall user experience with faster app launches, concurrent use cases, smoother and responsive UX, and richer photo and video experiences.

The 4G LTE mode, based on 12nm process technology, has been significantly improved from our previous platform with a dedicated DSP, low power features such as eDRX ,platform-level power management, support for Cat 4/3/1 and single/dual antennas.

Smarter Always-On (AON) Co-Processor: Enhanced AON co-processor supports richer offloaded experiences. We have partitioned memory and performance to enable up to 64K colors (from 16 colors) and extend offload experiences to include continuous heart rate monitoring and sleep for health and wellness, faster tilt-to-make responsiveness, step counting, alarms, timers, and haptics for a more capable traditional watch mode.

Ultra-Low Power Platform: Low power optimizations include 12nm low power process technology, dual DSPs for optimal workload partitioning, support for dynamic clock andvoltage scaling, Qualcomm Sensor Assisted Positioning PDR Wearables 2.0, low power location tracking support, and an enhanced Bluetooth 5.0 architecture. These improvements are designed to deliver more than 25% power reductions across key use cases and bring extended battery life to the platform (compared to the previous platforms).

Richer, Enhanced Experiences: The hybrid platform approach brings rich, enhanced experiences across interactive, ambient, sports, and watch modes. In interactive mode, the platform supports additional immersive experiences with camera, voice assistant, and voice/video messaging. Further, in ambient mode, the increase in the number of colors from 16 to 64K and number kerning is designed to make readability crisper and offers more exciting design options. In sports mode, offloaded maps enhance the on-the-run experience. The traditional watch mode includes features such as heart rate, steps, alarms, reminders, and battery indicator, with minimal impact on performance or battery life.

Snapdragon Wear 4100 Platform

Graphics and animations are now more dynamic. It comes with enhanced camera, video calls, and more. The company says the transition between the Ambient Mode to the normal mode will be more seamless.

Snapdragon Wear 4100 Platform SKUs and Availability

The Snapdragon Wear 4100 platforms come in two variants:

  • Snapdragon Wear 4100+ platform which includes the main SOC (SDM429w or SDA429w) and the AON Co-Processor (QCC1110), along with the companion chips including PMIC, RF for Modem/GPS and WiFi/BT, and RFFE
  • Snapdragon Wear 4100 platform which comprises of the main SOC along with the companion chips

The Snapdragon Wear 4100 platforms support both the Android Open Source Platform (AOSP) and the Wear OS by Google OS platform. Snapdragon Wear 4100+ and Snapdragon Wear 4100are available and shipping now.
