Snapdragon Wear 4100 and 4100+: the new 12nm watch processors promise much more performance and autonomy

It was in September 2018 when Qualcomm announced the Snapdragon Wear 3100, its new processor for smart watches He came to refresh the Snapdragon 2100 with a DSP chip, a coprocessor, a big-little-little architecture and an ultra power saving mode. Now, and despite the fact that there were rumors about a possible Snadpragon 3300, we already have here its successors: the Snadpragon 4100 and 4100+.

The two brains focus not only on power and autonomy, but they jump to 12 nanometers. The big difference between them is that the 4100+ model, in addition to the main processor and all the additional chips, such as PMIC, GPS, WiFi, Bluetooth and RFEE, includes the coprocessor and only supports Wear OS (the Wear 4100 supports Wear OS and AOSP).

Up to 85% more performance and 25% less energy consumption

After clarifying the differences between the two models in the Snapdragon 4100 series, we will focus on the most advanced of them, the 4100+. This new processor is built in a 12 nanometer process and Composed of four 1.7 GHz ARM Cortex A53 cores “optimized for wearables”. The main processor can be an SMD529W or SDA429W, while the coprocessor will be a QCC1110.

This secondary processor will deliver Always On experiences, such as ambient mode, sport modes, and traditional watch mode. It is capable of running alone when tasks do not require the power of the main processor and, unlike its predecessor, can represent up to 64.00 colors in ambient mode.

RAM is LPDDR3 at 750 MHz instead of 400 Mhz and the GPU becomes the Adreno 504A instead of the Adreno 304, while the ISP is dual and now offers support for cameras up to 16 megapixels. All of this translates, according to Qualcomm, into the fact that the Snapdragon 4100+ provides, compared to the 3100, 85% faster memory and processor speed, a GPU 2.5 times faster and a camera with twice the resolution.

On the other hand, Qualcomm ensures that energy efficiency has improved offering dynamic clock speeds, voltage scaling, low-power geolocation support and “improved Bluetooth 5.0 architecture”, which will result in power consumption of up to 25% lower than the previous generation.

And in terms of connectivity, the Snapragon Wear 4100+ integrates up to Bluetooth 5.0, WiFi in the 2.4 GHz band, NFC, GPS (GPS, Glonass, Beidou, Galileo) and the X5 LTE modem. With this, manufacturers who choose it will be able to offer global connection Cat 4/3/1 LTE in two or one antenna configurations.

When and in which models will we see these new processors? Qualcomm confirmed that imoo and Mobvoi will be the first manufacturers to bet on this platform: imoo will launch the Z6 Ultra within 30 days, while Mobvoi will deploy the latest version of Qualcomm in the new Tic Watch Pro.
