The Snapdragon Wear 5100 Will Continue to use Cortex-A53 Processors

In terms of efficiency, Qualcomm’s Snapdragon Wear 4100 series chipsets feel horribly obsolete, especially because they target the form factor with the largest battery constraints. Although the firm claims to have a new design in the works to remedy this issue, it appears to be a half-measure.

According to WinFuture, the Snapdragon Wear 5100 would have four Cortex-A53 processors. Samsung’s Exynos W920, for example, contains two Cortex-A55 processors. Overall, this results in lower performance, but it is a boon for power efficiency, which is crucial. When compared to its predecessor, the Cortex-A53, the A55 “delivers up to 18% more performance at 15% better power efficiency,” according to ARM.

Qualcomm is said to be putting the processor through its paces in a variety of combinations. Some models offer 2GB LPDDR4X RAM and 8GB or 16GB eMMC storage.

The new design will also have an upgraded AON co-processor, which can handle simple background tasks such as counting steps and refreshing the Always On display as needed while using significantly less power than the main CPU cores.

Of course, the fact that the Exynos processor is made on a current 5nm node accounts for the majority of its efficiency. The Wear 4100 series was created using a 12-nm technique that has been around for a long time. According to the information available thus far, Qualcomm has tasked Samsung’s foundries with producing the 5100 chip; however, it is unclear which node would be used.

SMIC, a Chinese business, is also mentioned, and it has a 14nm foundry up and operating, as well as a sub-10nm line ready to go. Instead of importing wristwatch chips from Samsung or TSMC, Chinese manufacturers would be able to source them locally.

The chipset will enable two cameras, one with a resolution of 16 megapixels and the other with a resolution of 5 megapixels. Some children’s watches include two cameras: one for taking images and the other for video calls with their parents. This could be useful in a variety of low-power applications.

It appears that the Snapdragon Wear 5100 will take some time to become available. Qualcomm would most likely strive to obtain orders from Chinese manufacturers, which, aside from Samsung and Apple, are the largest smartphone vendors (but those two prefer to use their own chipsets).
