Qualcomm introduced two new smartwatch chipsets at once: Snapdragon Wear 4100 and 4100+. This is the first major update since 2018 when the Snapdragon Wear 3100 chip was presented. Although, by and large, the 3100 model did not differ much from the Snapdragon Wear 2100, but it was shown at all in 2016.
New chipsets are significantly faster than their predecessors. The processor is made according to the 12 nm manufacturing process (versus 28 nm), four Cortex-A53 cores operate at a frequency of up to 1.7 GHz (versus 1.1 GHz). This gives a 85% increase in productivity. In addition, Adreno A504, which is about two times faster than the Adreno A304, used in the Snapdragon Wear 3100, is used for graphics processing.
The differences between the Snapdragon Wear 4100+ and the Snapdragon Wear 4100 are in the presence of an updated version of the QCC1110 coprocessor, which is responsible for the always-on functions. If the manufacturer does not plan to endow their devices with such capabilities, he can use the regular version of Snapdragon Wear 4100.
The QCC1110 in Snapdragon 4100+ offers advanced features for operating the Ambient Display mode. The watch will be able to display up to 64 thousand colors (previously only 16 were available), as well as show additional information – the number of steps, heart rate, charge indicator, reminders, etc.
Snapdragon Wear 4100+ and Snapdragon Wear 4100 support Bluetooth 5.0, NFC, have an integrated LTE modem. Qualcomm notes that the use of a more modern technological process has allowed to achieve better energy efficiency of chipsets. The battery life of smart watches should increase by about 25%.
Qualcomm has already started shipping new chipsets to smartwatch manufacturers. The first devices with Snapdragon 4100+ and Snapdragon 4100 should appear on the market in the coming months. Mobvoi has already announced that the new TicWatch will be equipped with the Snapdragon 4100 series.
Do you think Wear OS smart watches still have a chance to somehow influence the smart watch market?
