Qualcomm has revealed a bunch of new chips, one of which is specially made for wearables.
The Snapdragon Wear 2100 has a 800MHz or 1.2GHz quad core CPU and an Adreno 304 GPU. The CPU cores use the oldish ARM Cortex A7 architecture which however is the most relevant one because of its efficiency. The Wear 2100 supports 400MHz LPDDR3 RAM and has integrated X5 cellular modem.
The Wear 2100 is supposed to be the 2016 SoC of choice for smartwatches and other small wearables. Especially the new chip is supposed to make the wearables thinner.
Qualcomm also released three lower-end mobile chips, 425, 435 and 625. The 625 has 2.0 GHz quad core Cortex A53 CPU made with 14nm process. The graphics are handled by the Adreno 506 GPU. The 400 series chips are made with 28nm process and also have quad core Cortex A53 CPUs but clocked lower at 1.4GHz. The GPUs are Adreno 308 on the Snapdragon 425 and Adreno 505 on the 435.
The 625 is going to bring much more power to the new premium mid-range category of smartphones. The 400 series chips are for the low-end devices.
