Snapdragon 835 chipset carries an octa-core CPU, Adreno 540 GPU and Quick Charge 4.0

As expected, some more information about the Snapdragon 835 chipset was released today in Las Vegas. The new high-end SoC features an octa-core CPU using eight Kryo 280 CPU cores. Four will be running at a clock speed of 2.45GHz. Those are the performance cores you use when you need the A-Team. The remaining four cores are running at a clock speed of 1.9GHz for efficiency...

If it charged to 50% in 15mins. Will it be full in 30mins? Or is the other 50% slower

Most likely slower after fifteen minutes. My S7 Edge charges blazing fast up to about 70%, and then the charging slows down after that.

Same with my Moto Z Force. It goes from 25% to 85% in a span of roughly 35min and then not too long after it's at 100%. Of course the fear that it will wear the battery down quicker is always on the back of my mind and QC4 is no different to me in that regard but I get to be charged and out of the house in a rather short time so...

This why OnePlus' solution seems better

This is inherent to batteries and heat dissipation while charging, etc. It has more to do with battery tech and nothing to do with the charging mechanism itself. OnePlus solution won't necessarily lead to faster times, though by shifting the heat load outside the device it may help, there's a point of diminishing returns. That all being said this article is full of useless buzz, I quote: "And the Adreno 540 GPU will crunch 60 times more colors and is 25 times faster rendering 3D than the Adreno 530." Seriously... it will really crunch 60 times more colors? What does that even mean? It's not like color spaces changed or we're using higher color pit depth and that is somehow dependent upon this piece of hardware. Someone must not have proof read the "25 times faster" claim, I doubt it's 25% faster, if it is I'll call it a major win.

The other 50% is slower. I'm not a battery expert, but from what I've read it's that last 20% of charge that takes just as long as the rest of the battery to charge. It has something to do with the voltage going from an increasing variable to a constant and then the battery needing less and less charge to fill it to capacity. I'm sure someone with a better understanding can explain it. Otherwise, I think it would also take longer to charge just because when you are charging a battery that quickly it produces heat and so I'm sure they've put safety measures in place to decrease the amount of voltage after a certain point so that the battery doesn't get hot too quickly.

Great comment.

And knowing Qualcomm, it will probably grill steaks and fry eggs.

Learn to value good things. It's not that you have to praise only Apple.

Who said anything about praising only Apple?

Yes you are correct, because people never learn from their mistakes and repeat them intentionally so that they could fall. /s

What are you btching about now?

There was one processor that they released that had a legitimate issue with overheating, and they've released a few since that haven't had any problems. I suspect they learned their lesson. The fact that they're making them more energy efficient means that there's less overheating as well.

41. Mxyzptlk unregistered

I hope so. I don't want my phone to fry. I haven't had any overheating issues with my 6P.

Neither have I, and yet the 810 is the SOC that gave QC that reputation... So why did you bring it up in the first place?

"27% performance boost over the last generation model. It is 40% more energy efficient" Reason why ARM is a great competitor for Intel. Especially if Microsoft bring Windows desktop OS to ARM.

The Exynos version of this Samsung's SoC, is also interesting.

Meanwhile Intel is like, "9% performance boost over the last generation models"

And the Intel New Core i7 Laptop class processors just show 6-7% increase in performance. 6700HQ is just 6% slower than 7700HQ. Disappointing.. But I am happy as purchased a notebook 3 months backs with 6700HQ it gives me same performance as the new 7th generation processors

I don't think it's a fair comparison, since laptop CPUs have been iterating for two decades, compared to one for mobile SOCs. And laptop owners only replace every what? 5 years? Compared to 2 for phones.

Ahhh the core battle again. Look at apple just 4 cores and they smash everyone. Time and time again 8 cores is not needed for smartphones. At least not this time.

Well, it's 8 cores but not really 8 cores. At least not in the traditional sense. It doesn't appear to me that this is using the ARM HMA where you can use all 8 cores at the same time. It seems more like this is the old-school Big.little where you use 4 cores normally and then it switches to another 4 cores for larger tasks. I could be wrong, but I did not see in any of the articles I've read that they are allowing all 8 cores to be used at the same time.

It'll probably be like the 810 where the app has to specifically call for all eight cores but that's only done for efficiency.

My motorcycle is faster than my car. Should I now blame Toyota saying their four wheels are slower than my 2 wheels of Yamaha? If you don't know s**t about CPU then please don't troll.
