Qualcomm has today announced Pro versions of several mid-range and budget chipsets. Just as the Snapdragon 821 was the Pro variant of Snapdragon 820, the Snapdragon 653 will take after the Snapdragon 652, the Snapdragon 627 will follow Snapdragon 625, and the Snapdragon 427 improves upon the Snapdragon 425.

The prominent changes include higher clock speed for performance cluster and GPU.


The Snapdragon 653 increases the clock frequency of 4 performance Cortex A72 cores from 1.80 GHz to 1.95 GHz. It can also support double the amount of RAM compared to Snapdragon 652 (8GB vs 4GB) and also updates the Modem to X9 LTE. The new Modem supports Enhanced Voice Services (EVS) codec for more clarity in VoLTE calls.

The Snapdragon 627 boosts the clock frequency of all 8 Cortex A53 cores to 2.20 GHz (up from 2.0GHz). It also adds Bluetooth 4.2 support and Qualcomm’s TruSignal antenna boost technology to improve cellular reception.

The Snapdragon 427, on the other hand, is very similar to Snapdragon 425, and the only difference is that the X6 LTE modem has been replaced by X9 LTE modem.
