The DSP doesn't just stretch audio play time, it also works for sensor processing for things like the Global Positioning System. Instead, the processor appears created to boost the feature list of affordable smartphones while keeping the costs significantly down.
The new 215 processor has four ARM Cortex-A53 cores and is the first chipset in the 2-series with a 64-bit CPU for up to 50% increased CPU performance. It's also set to be more power efficient, as it apparently uses a 12nm process, compared to the Snapdragon Wear 3100's 28nm.
The WinFuture report suggests that Qualcomm is working on a Snapdragon Wear 429 chipset (or might be Snapdragon Wear 2700), which is said to be built on 64-bit architecture - a significant shift from the current chipsets. Google requires 64-bit apps, as it prepares for future Android devices that only support 64-bit code.
As for its graphics processing unit, the new Adreno 308 offers just a mere 28 percent boost in performance. It is the first within the 200-sequence to have dual image sign processors (ISPs), so it may well help paired cameras for portrait results. This brings important features like optical zoom and depth sensing. The processor also enables 1080p video recording at 30 frames per second. The chipset also will support HD+ display with 1560 X 720 resolution which would let more budget phones to enter the market soon with the chipset inside.
The Qualcomm 215 shines in the connectivity department as well.
For superior cellular connectivity at home or on the go, the Qualcomm 215 featuring the integrated Qualcomm® Snapdragon™ X5 modem supports LTE Cat 4 with Carrier Aggregation for faster data rates and download speeds up to 150Mbps. The processor supports EVS Voice calls which simply means devices will offer "Ultra HD Voice Calls". Many of these features were earlier a selling point for more premium smartphones. And those who haven't used a Wear OS device would probably be unlikely to switch as they are already locked into another platform. For example, the chip is the first to support dual SIM cards with dual VoLTE, and also the first to support NFC payments on Android, which theoretically means that you can use a 200-series chip for POS transactions.
