Qualcomm Snapdragon 653, 626, and 427: Qualcomm Announces Successors to Popular Mid-Range SoCs

Qualcomm is one of the world’s most renowned mobile chipset manufacturers and 2016 has been a good year for Qualcomm so far — the Snapdragon 65x series has garnered rave reviews for providing stellar performance in the mid-range market segment, and the Snapdragon 820 and Snapdragon 821 received an improved critical reception over the Snapdragon 810. To build on the successful year, at its 4G/5G summit in Hong Kong, Qualcomm announced two new SoCs in the mid-range Snapdragon 600 series, the Snapdragon 653 and Snapdragon 626. For the entry-level tier, the company is rolling out the Snapdragon 427.


The 653, 626, and 427 all receive a new X9 LTE modem and support for Quick Charge 3.0 and dual cameras. This X9 LTE supports Cat 7 downlink speeds of up to 300MBps, and Cat 13 uplink speeds of up to 150Mbps (up to 50% better than the X8 LTE’s uplink speeds).It also supports LTE Advanced Carrier Aggregation with up to 2x20MHz in both downlink and uplink, 64-QAM in uplink, and better call clarity and reliability on VoLTE calls with the company’s Enhanced Voice Services technology.


The new Qualcomm Snapdragon 653 SoC, which as you may have guessed from the number, is the most powerful chipset of these three and is an incremental upgrade over the Snapdragon 652. When compared to its predecessor, the Snapdragon 653 provides an improvement of up to 10% higher performance and twice the addressable memory, with support for 8GB of RAM now. It also adds Enhanced Voice Services, which apparently makes VoLTE calls sound even better, better GPU performance, and other improvements in its architecture.


The Snapdragon 626 also sees a 10% increase in performance from the 625 thanks to a bump in CPU clocks on its two Cortex A53 clusters to 2.2GHz from 2.0GHz. The 626 comes with Qualcomm’s TruSignal antenna boost technology, which is designed to improve signal reception in congested areas.


Towards the low end of the market, the Qualcomm Snapdragon 425 is seeing an upgrade in the form of the Snapdragon 427. The biggest improvement is the modem on this SoC, which is now an X9 LTE modem with support for Category 7 LTE downlink and Category 13 LTE uplink. This is a substantial improvement over the X6 LTE modem that was used in the Snapdragon 425 and 430, which was only capable of Category 4 and 5 downlink and uplink. Qualcomm is pushing for adoption of their Clear Sight technology relatively heavily, with even the Snapdragon 427 gaining support.

The Snapdragon 653 and 626 will be available before the end of the year, while the Snapdragon 427 will be making its way to consumer devices early next year.
