What is the new Snapdragon 835 mobile chipset, what phones will it feature in and how does it compare with the existing Snapdragon 821 and 820 processors found in most of the biggest handsets of 2016? Here’s our full Snapdragon 835 vs 821 vs 820 processor comparison.

Qualcomm has just revealed some juicy details of the Snapdragon 835 mobile chipset, the processor that you’ll likely find stuffed inside a lot of flagship phones in 2017 – including the massive Galaxy S8 from Samsung.

Here’s how the Snapdragon 835 compares with the Snapdragon 821 (found in Google’s Pixel phones and the fresh new OnePlus 3T) and the Snapdragon 820 (packed into most of the big 2016 phones like Sony’s Xperia XZ and the Samsung Galaxy S7).

What is the Snapdragon 835?

Qualcomm’s latest premium mobile chipset has been revealed as the Snapdragon 835, succeeding the existing Snapdragon 821 and 820 as the processor of choice for super-powered Android smartphones.

The Snapdragon 835 was crafted in collaboration with Samsung, and its major talking point is the 10-nanometer process node, which in layman’s terms means increased efficiency, or improved performance compared with previous Snapdragon chipsets.

How does the Snapdragon 835 compare with the 821 and 820?

The Snapdragon 821 was a minor upgrade compared with the Snapdragon 820, offering a 10 percent boost in performance and more efficient power usage. But the Snapdragon 835 is a bigger leap forwards, as the naming might suggest.

For a start, you get a 30 percent increase in area efficiency, meaning the 835 can take up less room inside a phone than previous Qualcomm chips. That could mean slimmer phones, or more space for a bigger battery and so on.

You also get up to a 27 percent increase in performance, or up to 40 percent lower power consumption, depending on a user’s priorities. That’ll make for blistering games performance, or a longer lasting battery life.

The Snapdragon 835 also supports Qualcomm’s new Quick Charge 4 tech, which delivers up to 20 percent faster charging than Quick Charge 3.0 (found in the Snapdragon 821 and 820). Here’s hoping it doesn’t heat up phones either.

What phones will feature the Snapdragon 835?

The Snapdragon 835 is already in production, which means you will see Android phones packing the processor arriving in the UK in the first half of 2017. We’re expecting the Samsung Galaxy S8 to be one of the first big mobiles of 2017 to sport the 835, followed by flagships from the likes of Sony and HTC.
