Qualcomm, one of the leading brands when it comes to modern-day mobile SoC’s, and here we’re going to talk about two more of its top of the line chipsets from its 800-series — Snapdragon 835 vs Snapdragon 821.
The Snapdragon 835 mobile processor (MSM8998) was the first one to get the advanced 10nm design, decreasing the size of the chip and increasing the performance.
The advanced design makes the chipset 35% smaller, consumes 25% less power and thus enables a longer battery life than Snapdragon 821 (MSM8996Pro).
The Snapdragon 821 had support for fingerprint sensors, but the Snapdragon 835 took one step further with its new Haven Security Suite. In addition to fingerprint, the more recent processor includes voice, iris and facial recognition.
