Snapdragon 821 Mobile Platform

As one of the most cutting-edge mobile processors ever created, the Qualcomm® Snapdragon™ 821 mobile platform with X12 LTE builds on the momentum of our Snapdragon 820 mobile platform. It is designed to support superior connectivity, graphics, photography, power and battery efficiency and helps set a new bar for smartphones, tablets, mobile virtual reality (VR) head-mounted displays and more.

Lightning-Fast LTE

The Qualcomm® Snapdragon™ X12 LTE modem offers 3x faster peak upload speeds and 33% faster peak download speeds compared to those of X10 LTE.

Immersive visual graphics

The Qualcomm® Adreno™ 530 GPU offers 40% improvement to graphics performance, compute capabilities, and power usage when compared to Adreno 430—giving the Snapdragon 821 processor a 5% performance bump over the 820 processor.

Spectra Camera ISP

14-bit Qualcomm Spectra™ Image Signal Processor (ISP) supports the capture of up to 28 megapixels with zero shutter lag.

Less time charging

With Qualcomm® Quick Charge™ 3.0, users can spend less time charging and more time doing. As our fastest and most efficient charging technology yet, Quick Charge 3.0 is up to 4x faster than conventional charging and 38% more efficient than Quick Charge 2.0.

Powerful Kryo CPU

The new Qualcomm® Kryo™ CPU has 2x performance and efficiency when compared to the CPU of the Snapdragon 810 mobile platform. The Snapdragon 821 goes even further with up to 10% performance increase over the 820 mobile platform.

Efficient Hexagon 680 DSP

The new Qualcomm® Hexagon™ 680 DSP is also designed to bring significant improvement to performance and battery life.
