Qualcomm Snapdragon 835 vs Snapdragon 821 and SD820: here's what the known differences are

Qualcomm just announced one of its top-tier chipsets for 2017 and its name is... Snapdragon 835. It will succeed the Snapdragon 821 as the manufacturer's top-tier chipset, once again proving that we still have no grasp on Qualcomm's naming philosophy.

While not enough specs and features got revealed, Qualcomm poured lots and lots of oil in the fire of our anticipation by letting us know that the silicon will be manufactured by Samsung on a 10nm FinFET process and employ Quick Charge 4.0 for a snappier recharging experience. This means that apart from a 30% smaller physical footprint, the upcoming Snapdragon 835 will be 27% faster and 40% more power-efficient in comparison with the Snapdragon 820, which definitely gets our hearts racing!

Quick Charge 4.0, on the other hand, will provide 20% faster charging in comparison with Quick Charge 3.0 and provide up to 5 hours of usage after merely 5 minutes of charging. Here's some more information about the hot new fast-charging technology on the block.

We thought it will be rather nice if we compared the Snapdragon 835, SD821, and SD820 in a neat table to showcase all these differences.

Personally I'm still wondering if quick charge 3 had something to do with the note 7 problems, given that as far as I saw only Snapdragon phones were affected?

Why PA mentioned a tabular comparison? When they don't have any info on the specs of 835.. 'N/A'

Quick charge 3.0 has nothing to do with it.
No other phone using it had explosion issues.

Also in Canada we had the exynos version and its was also recall because of risk of explosion.

Its more a mix of the design of the phone itself and the battery used.

The S7 Edge had it too...right?

Quick Charge is simply a circuit that allows for more current to past to a battery design to handle higher voltage and quicker charging.

The connector itself is irrelevant to quick-charging.

I am sure Samsung tests the QC on the S7's, so why would it all of a sudden be an issue on the Note 7?

I think it was a bad component that handles the voltage coming to the phone.

Exactly what I was thinking. Poor journalism at best

They did global recall of all types, regardless of chipset, they weren't chancing anything, which is understandable to me.

However I'd only heard of snapdragon one's having actually anything happen, so I do wonder.

Not 'entirely' as in snapdragon one, yes, eynox version, no, same with note having 2 versions last I checked, hence I wonder, since I haven't heard of any eynox versions having issues?
Eyxnos version has its own kind of quickcharge made by samsung or was it someone else, but the point is, it is different, and if only snapdragon powered had issues, then there might be something to it?

Remember, its a SOC, that one chip, could easily be the problem, depending on what where how, but the quickcharge does interact with the battery so it could be it?

Why would you post a table comparing the new Snapdragon 835 when almost all of the information you want to compare is "N/A"?

27% faster isn't enough to beat the A10 big.Little

You do realise that performance increase was from the node shrink alone, right? The final performance will be higher.

It's just the gain from the shrink, the final performance numbers will be unveiled when the dev kit will be available later this year.

We can be sure that it will be more than 27% gain, but not sure how much.

What will be better single perfomance gain or multicore a10 was very balanced this year
But weak in sustained performance
10nn will help in this side
In theory flagship devices will fly running nougat which is not a OS that prioritize perfomance like I see with every new IOS beta launched

Single core is always better but really hard to do. Multi core is easier to do but beyond a certain number of threads we reach diminishing returns.

Nougat does prioritize performance. It just takes a few days to settle in.

Until you leave your phone one night for charging, apps will run on JIT compiler which will slow down loading times.

Once it sits overnight, it will compile apps and then will use AOT compiler, and hence will be faster.

Just because it works differently than marshmallow doesn't mean it's slower.

27% faster if they use the exact same core.

They will also improve the core so its will stack up.

usually its at least 25% improvement from the core architecture then another 27% on top with the new process..

thats if they stay at 4 core..

if they make it 8 core...

27% increase from 820? Weak! These numbers can't beat the A9 in GB4. LOL!!! Try again Qualcomm. You are behind the times...

It's just Quick Charge 4, not 4.0

basically... we know nothing about SD835 except that 10nm and QC4.0
