The Snapdragon 821 clocks in at 2.4GHz. That’s up from 2.2GHz on the previous model. AnandTech notes that it should also offer an improved Adreno graphics processor and a higher clocked power cluster, but Qualcomm hasn’t revealed those details yet.
The Snapdragon 821 is a relatively minor upgrade, but you may still notice the difference in your next smartphone. The new chip will likely power most of the flagship Android phones (along with tablets and even some virtual reality headsets) set to launch in the second half of 2016 and onward, at least until Qualcomm rolls out an even better model further down the line.
