Well, to be technical, 14nm and 16nm do actually correlate to the physical structure of the chips, very directly. 14nm is a smaller manufacturing process, leading to smaller physical structures on the chip itself.

Usually decreases in CPU manufacturing processes results in higher performance and lower power consumption, but that's not always the case.

no..

20nm, 16nm, 14nm relates to the minimum feature width, which relates to the fin width. but again the M1 pitch is 64nm for all.. Meaning they are all effectively the same nodes.

As it has been mentioned, All major foundries producing 16/14nm finfets are using 20nm planar backends with intel using 22nm.

Here are my geekbench battery test results. I have the iPhone 6S 16GB, Samsung chip.

Makes me wonder if there's some kind of incompatibility between the Samsung chip and that test,

Or if that test just isn't reliable.

I think we'd be flooded with complaints if that represented real world for millions of iPhones.
 
something I'm wondering if anyone is willing to share, I've noticed the graph from that unsigned app people were using has swung towards TSMC quite a lot compared to release, I have also seen a lot of people who recently got their phones have the TSMC, I was just wondering if maybe since the early batches Apple has been using less Samsung chips and more TSMC ones in phones manufactured after release, after all it sounds like TSMC were Apple's preferred supplier as they manufactured the A8 and will manufacture the A10 (or so people have been saying?), and it sounds like Samsung were contracted as well to help meet demand. if anyone could follow up on this it could give an idea if this is true or not.

personally I think it's far to early to be returning your phone over one focused benchmark, I've seen people say they are returning their phones because the TSMC chip was the bad one, now it's the samsung which is the bad one, who knows, the Samsung chip might be superior when it is idling and then everyones going to want that one again. :p

I honestly think people just don't compare their phones with others and just believe that their battery life is how it should be.
 
Should we measure performance also in real life, not by Geekbench scores? I see your point, but it's mucher harder to compare then.

What if the samsung one is more efficient when idling? If you are a really heavy user I could see the benefit of a TMSC but there is no indication yet that the samsung chip is doing worse in real life use.
 
That's fantastic news for all the Samsung folks! Great news guys!

He was sarcastic, probably.
Anyway, if there is any difference in the chips I'm going to ask if I can use the phone in store to see what chip I have, and exchange it immediately.

Well it can be measured and it's possible that Samsung idles better, but it can be hard to find volunteers to idle their new iPhone 6s for 16 days... Looong boring test...

I doubt that Samsung idles significantly better, but that's just my personal guess and could be wrong.

I agree. I think the Geekbench test is not accurate; it hasn't been updated for the iPhone 6S release anyways, so its very likely that there are some incompatibilities/bugs with the two chips. It must using more CPU cycles, as performance seems to be identical between the two chips. I find it hard to believe that Apple would release two chips with a consistent 20% power consumption difference.
 
This really stresses me out. I had a 128GB iphone 6 and now I have a 128GB 6S. Honestly, before any of this came about I complained about the battery life of the new phone. I chalked it up to playing with it a lot more, getting a new Apple Watch and the fact the new phone had a smaller battery.

Well, now I know I have the Samsung chip and I have to wonder if I could exchange it and try to get another?? Who doesn't want 20% battery life? I am having to charge up at least once, or twice a day during the day.


What if I get another Samsung though? My gf has a 64GB 6S Plus and hers is a Samsung also.

Anyone know how Apple is treating it? I bought my phone from the ATT store do I return it there or take it to Apple?

I have AppleCare+.

Lots of people in this thread say they have a TSMC chip and complain their battery life sucks tho??

As if Apple never released any of their products that varied in performance before! Macbook Air with different SSD suppliers and significant performance difference, anyone?

I hardly doubt it could be the so-called incompatibility of the Geekbench and the Samsung chip. Sounds like pure nonsense to me! It stresses the devices in a common way. There is nothing to tweak in the test, so it could stress the Samsung chip less than it stresses the TSMC one.
I had both and I could definitely tell that the Samsung one ran hotter! All the tests show the temperature difference as well (37 vs 40 celsius).
Most likely the Samsung chip is less power efficient while performing more complex and long tasks. I'm waiting for Anandtech to shed more light on it! Mark my words! Real life difference might not be as drastic as 20% but it's there for sure, maybe closer to 10%. Average users are not gonna feel it anyways.
 
Stressed out about what? If this thread was never made NO ONE would have any clue in real life. People really need to stop being so OCD about a phone; it's actually humorous now that people are getting physically stressed about the brand of processor their phone has out of all things in life that they would never know a difference but not for reading this thread.

ABSOLUTELY NOTHING has been proven definitively one way or the other yet; right now it is like phantom pains. You hear something bad so you tend to scrutinize yours that much more until you convince yourself there is a problem.

Stressed that my battery life is not all that it could be. Probably the most important part of a phone. I complained the iphone 6 was too skinny and wished they made it's battery life better.

I just got an apple watch, that drains the battery more during the day... and as I said before I even read this thread I was pretty unhappy with my battery life. I really would like the opportunity to see if I could really improve my battery by 20%.

Tested my 128GB 6s Plus with the Lirum Device Info Lite app on the App Store, and I've got the TSMC chip (N66mAP). I'm actually quite pleased with battery life on my device, as it seems better than how my 6 Plus performed, not to mention I have a ton more apps, now that I've got 128GB of space to play with.

Considering that Samsung has been found to cheat or have questionable results on their performance tests, I really wouldn't be surprised if they fudged their results in order for Apple to sign off on the mass production of their chips. Sure, they've been in previous iPhones, but I just can't ever trust them fully. Apple really is "sleeping with the enemy."

To all those returning / exchanging your phones due to: armchair engineer comments, internet rumors, (unoptimized) benchmark apps that don't prove anything considering the variables involved among phones, and a total disregard of actual battery capacity in the phones (I have yet to see anyone post actual battery capacity / health of their phones, which could be the culprit)-- thanks for ensuring that we all pay even more for AppleCare going forward and/or Apple tightening up its return policy. This whole thing is so ridiculous.
