Samsung latest 5nm node process-based Exynos W920 turned out to be a great smartwatch chipset with the same level of performance at better battery life than the previous gen.
WinFuture claims that Qualcomm is fighting back internally testing two chipsets with the model number 'SW5100'. These will likely be called Snapdragon Wear 5100 and Wear 5100 Plus.
Both the variants have four ARM Cortex-A53 cores at 1.7GHz and Adreno 702 GPU clocked at 700 MHz. It will also feature LPDDR4X RAM, eMMC 5.1 memory, LTE connectivity, Bluetooth 5.2, and connectivity to 5GHz Wi-Fi networks (802.11c). There’s no support for 5G, though.
While the clock speeds are slower than the previous-gen Snapdragon 4100 platform the rest of the specs are rather good. The Snapdragon Wear 5100 and Wear 5100 Plus will be manufactured on the 4nm node process. For context, the previous-gen Wear 4100 was based on the 12nm node process (the lesser, the better). Shift to a smaller node process should (theoretically) deliver better performance and better battery life.
The Wear 5100 uses a "Molded Lesser Package" or MLP with the SoC and the power management controller as separate components. The Wear 5100 Plus is said to use "Molded Embedded Package" which will have SoC and power controller in the same package. The Plus variant will also have a separate QCC510 co-processor for low-power mode, much like the current Wear 4100 Plus platform.
QCC510 co-processor should take away tasks like Bluetooth and Wi-Fi communication, turning on the always-on-display, delivering notifications, and even fall and heart rate variance detection. This should help in taking away some tasks from the main processor.
There's no word on the availability or even an announcement of the Snapdragon Wear 5100 platform.
