Qualcomm released two new Wear OS processors today, namely Snapdragon Wear 4100 Plus and Snapdragon Wear 4100, which is the first major update of the smart watch platform since 2018. The Snapdragon Wear 4100 SoC finally abandoned the Cortex-A7 core and 28-nanometer process, and switched to the Cortex-A53 core and 12-nanometer process. Although this does not have epoch-making significance, it has great performance and energy efficiency.
Qualcomm claims that the speed of the new chip will be greatly improved, and the GPU, memory, camera and battery life will also be greatly improved.
The last major revision of the Snapdragon Wear series was the Snapdragon Wear 3100, which was a minor update of the Snapdragon 2100 in 2016. In fact, given that the main processors of the 2100 and 3100 are identical, the debut of the 4100 marks the first qualitative improvement in Wear OS in four years or so.
Qualcomm continues to use the main SoC + coprocessor architecture on the smart watch platform. Wear 4100 is used as the main processor chip for active and interactive use of the device, while an auxiliary coprocessor is used as an always-on chip to enable non-interactive device usage in the environment, such as through static and low update information Turn on the screen.
The biggest change this time is in the process of the processor. The Wear 4100 series chips jumped from the 28-nanometer process to the 12-nanometer process. Four A53 CPU cores with a clock frequency of 1.7GHz replaced the A7 core of 3100 (only 1.1GHz). Qualcomm says its performance has improved by more than 85%. The GPU is now Adreno A504 (twice and a half faster than 3100) and faster memory.
Wear 4100 Plus' QCC1110 co-processor can display 64,000 colors, and supports continuous heart rate tracking, alarms, haptic feedback and more. Wear 4100 series uses a new 12-nanometer CPU architecture, battery life will be increased by 25%.
Qualcomm is already shipping Wear 4100 and 4100 Plus chips to hardware manufacturers, and the first batch of devices will be available in the coming months.
