The San Diego giant has presented the Snapdragon Wear 4100 and Snapdragon Wear 4100+, two new SoCs whose main objective is to achieve the best possible balance between power and performance to offer an important qualitative and quantitative leap in the smartwatch sector.
Both chips are based on the Snapdragon 429, although they have important novelties to adapt to the peculiarities of clothing gadgets. In the attached image we can see all the elements that the Snapdragon Wear 4100+ includes. Although it maintains the same base as the Snapdragon Wear 3100, in fact part, like that, of a big.LITTLE configuration, at the silicon level it presents a much more complex structure.
The Snapdragon Wear 4100+ not only incorporates the processor, but also integrates a coprocessor in charge of the “always on” function, key to the low power states that keep the screen connected, as well as the other complementary elements that include the PMIC, RF for modem, GPS and Wi-Fi, Bluetooth, and RFFE. It is important to note that the Snapdragon Wear 4100 comes without the coprocessor dedicated to the “always on” function, and that this is the only important difference that it presents compared to the “+” model at the hardware level.
Regarding software level compatibility, the Model 4100 works with Wear OS and AOSP, while the 4100+ model only works with Wear OS.
Snapdragon Wear 4100: 64-bit and up to 85% more performance
Qualcomm’s new SoC is built in the 12nm process and its CPU uses the 64-bit Cortex-A53 architecture. Dispose of quad-core at a frequency of 1.7 GHz and it has a Adreno 504 320 MHz GPU, a major leap from the four 1.1-bit 32-bit Cortex-A7 cores and the 200-MHz Adreno 304 GPU mounted by the Snapdragon Wear 3100.
This simple comparison allows us to understand why there is up to 85% difference in terms of performance between both generations, but they are not the only changes that we must take into account. According to Qualcomm the GPU is 2.5 times more powerful, and the new platform allows sensors of up to 16 MP to be mounted, double that of the previous generation.
We also found improvements in the coprocessor dedicated to maintaining the “always on” function. If you look at the image that we accompany just below these lines you will see that said solution offers a broader set of functions and is capable of working with 64,000 colors, Another important leap in front of the 16 colors of the previous generation.
Qualcomm has also confirmed support for 750MHz LDPDDR3 memory and eMMC 4.5 storage, as well as the integration of a dedicated DSP and compatibility with the 4G LTE standard.
Higher performance and better features, but also lower consumption. As we can see in the image that we accompany just below these lines, the Snapdragon Wear 4100/4100 + platform from Qualcomm is capable of reducing consumption significantly. According to Qualcomm we can expect, on average, a 33% improvement in terms of efficiency in front of the Snapdragon Wear 3100.
At the moment, none of the best-known giants in the sector has confirmed that it will launch a smartwatch based on this platform in the short term, but we know that less popular brand models are on the way, Among which we can highlight the Mobvoi TicWatch Pro 3, a new device from Suunto and the Z6 Ultra for children from the imoo firm.
