After years of repackaging the same basic smartwatch chip over and over again, Qualcomm has graced Wear OS with a modern smartwatch SoC. Meet the Snapdragon Wear 4100, a Qualcomm smartwatch chip that, for the first time ever, is faster than the previous chip.
The Wear 4100 uses four 1.7GHz Cortex A53 CPUs built on a 12nm manufacturing process, a major upgrade from the 28nm Cortex A7s that every other Qualcomm smartwatch chip has been up until now. It’s not the state-of-the-art 7nm process that Qualcomm’s high-end chip uses, and the Cortex A53 is an old CPU design, but for Qualcomm, it’s a major upgrade. Between the new CPU, the Adreno 504 GPU, and faster memory, Qualcomm is promising “85% faster performance” compared to the Wear 3100.
There are actually two versions of the 4100, the vanilla “4100” and the “4100+.” The plus version is specifically for smartwatches with an always-on watch face, and like previous Wear SoCs, comes with an extra low-power SoC (based around a Cortex-M0) to keep the time updated and log sensor data (like step counts). Qualcomm is promising a better display image quality in this low-power mode, with more colors and a smoother display.
