Qualcomm Launches Snapdragon Wear 3100 Platform for Smartwatches
 

Qualcomm this week introduced its new platform designed for smartwatches based on Google’s Wear OS. The long anticipated Snapdragon Wear 3100 packs four general-purpose processing cores as well a special co-processor for low-power operations designed to prolong battery life of upcoming wearables. Communication capabilities of the platform include GPS, Wi-Fi+Bluetooth, as well as 4G/LTE, which is in line with features supported by direct predecessor.

Qualcomm’s Snapdragon Wear 3100 (MSM8909w) is the company’s most powerful SoC for wearables that the company has released to date. Just like the Snapdragon Wear 2100 introduced in 2016, the new chip packs four ARM Cortex-A7 cores clocked at 1.2 GHz. Meanwhile, the latest SoC also integrates the company’s QCC1110 co-processor designed specifically for tasks that do not require serious compute horsepower, such as sensor processing in new modes to be supported by the upcoming version of Wear OS. The co-processor also has a deep learning engine for custom workloads like detection of keywords.

Besides general-purpose cores and the co-processor, the SoC integrates Qualcomm’s Adreno 304 GPU that supports resolutions up to 640x×480 at 60 Hz as well as a high-performance DSP. As for communication capabilities, the Snapdragon Wear 3100 platform can support Qualcomm’s WCN3620 Wi-Fi/Bluetooth controller, Qualcomm’s Snapdragon X5 4G/LTE modem, and GPS capabilities. Meanwhile, the company will offer three versions of the SW3100 targeting smartwatches with different comm features.
