Tests confirm marginal difference between Samsung, TSMC-made A9 chips in Apple's iPhone 6s

    I think the fact that not only does the Samsung's smaller chip NOT perform better, but actually performed 28% worse is the big story. Test 1000 phones, you'll see that the Samsung chip still performs contrary to what we would expect. Even if the chips did equally, the smaller chip would be a disappointment.

    Being a frequent mobile gamer, I would pick TSMC version any time of the day. 

    For non-gamers (with what Apple identifies as a "normal use") indeed it would not make a difference.




    Basically the Samsung processor uses about 30% more power when it is under heavy load. Generally speaking, the processors in the phones spend most of their time at very low loads, so unless you're actively taxing the CPU for hours on end (e.g. by running benchmarking software), I'm not sure if you're likely to see a difference. Games might be a case where you do actually see a difference, especially in games that tax the CPU in addition to the GPU.

    Who cares? Based on all available data, Apple's not going to replace one iPhone for another.
    Get over it.

    I smell a class action from the megahertz obsessed.

    I bet if they tested 2 TSMC phones they would test differently


    Don't be silly, if they tested 2 TSMC chips and they performed differently, TSMC would be out of business. Six sigma originated in the electronics business.

    We're doomed I tell you.  Dooooomed.

    Then they will lose because both chips perform within spec.

    So, the Lyrium app designer is forced to disable chip ID for these new phones IMMEDIATELY.

    And we have a 28% difference showing. Has Apple ever looked more shifty? They are looking to be outdoing themselves on this one, which takes some doing!

    I think Geekbench 3.4 (App Store) can ID the chip.

    Still wouldn't be good as Apple would have to reveal a whole lot of their testing methodology and results. Apple would want to avoid it getting to that point.

    WRONG.

    The way I look at it the Samsung chip is at Spec.  It meets Apple's requirement for efficency for the A9.
    The TSMC chip over performs Apple's requirement.  What do you want Apple to do?  Make the TSMC chip less efficent? Ridiculous.
    What part of the post is wrong? :rolleyes: (Answer: None of it)

    Doesn't matter one whit how you (or I or anyone else here) look at it. If a class action would happen to be certified it would only matter how the court looked at it, while considering the evidence that Apple would be ordered to begrudgingly submit during discovery. I can assure you they won't task you with sorting it, nor would Apple be happy with revealing it IMHO.

    Strange that you raise the issue of whether or not the chips perform to specs and/or efficiency then use that to claim I was emphatically "WRONG" about something I wasn't discussing.

    Has anyone here taken their iPhone to Apple and see if it will be replaced?

    "As Anandtech explains, any chip manufacturing process—even within the same fab—will result in a range of performance, just as not every cookie baked from the same recipe will be exactly the same. By defining minimum tolerances, though, a customer like Apple can establish an acceptable range of performance. The chips that don’t live up to those minimums don’t make it into the devices. Those that do can still perform differently."

     

     

    “This can only be reliably tested on a device, but if all else were equal, I could see single percentage points difference between Samsung and TSMC,” says Moorhead. Even testing on a single device, though, wouldn’t be enough, since a single system on chip doesn’t speak for all of them. You would need to test many, many devices to be sure of any significant differences.

    Fortunately, someone has done just that: Apple.

    This is true, we used to test each chip from a complete wafer, the die location on the wafer would be noted and then we would test them all. It was not unusually to have performance differences across the wafer, most time certain location on the wafer would yeild vastly better parts, knowing this you could cherry pick the fastest and slowest parts. Intel does this, they map the wafers to know which parts perform the best then mark them as higher speed or grade part and sell them for a lot more. Since Apple is not selling their chips and they do not make phones which run at different clock rates like the typical PC it would not surprise me to see some phones run better than others. Apple most likely is not cherry picking their processsor or only shipping processor would closely look the same as each other.  I bet you could find a group of phones which behave completely different than another group.

    They promise performance X, delivered X,. With TSMC you get X and a bit more, that's it, not conspiracy or drama.

    You're fracking ignored because of your utter lack of logic from now on.

    So what if in games or anything making good use of the CPU, you lose 33% extra battery with a Samsung build.

    You still have an iPhone, get over it, Apple is always in the right, no matter what.Its a non issue yet again!

They are the same apps I have been using all the time.  I closed a few apps.  The battery seems still going down fast.  I fixed this by rebooting.  It seems the problem is not the app.  The problem is some process owned by iOS 9.  Apple quality is getting worse.  After I upgraded to iOS 9, the phone works worse here and there.  




    Try opening up the settings and check the battery usage stats. There's now a little clock icon that will show you how much everything has used by percentage and time both foreground and background over 24 hours or 7 days. Odds are somebody like FaceBook is being a bad little app while it's tucked away in the background. When I'm tight on power access, say when wandering around visiting a new city, I throw apps overboard rather than leave them lurk: a double click of the home button or that left side 3d Touch swipe (for S series phones) and I start flipping apps off to the top to shut them down.

     

    OR you got a lemon and should replace it as is your right unless it's an old iPhone 3 or something since you didn't specify.

    Neither uses TSMC 16nm nor uses Samsung 14nm. That are just names for the process node.

    Think of them as Charles and George and then ask yourself:

    Is the Charles process faster than the George process because the name starts with a C? 

    Or is the George process more efficient than the Charles process because the name includes two 'e's instead of only one?

    If you tested 1000 TSMC chips against 1000 Samsung chips, you will still see that the TSMC chips consistently score faster because of the extremely tight tolerances allotted to chip production. 

     

    This has been a great advertisement for TSMC.

    I looked.  I did not spend too much time looking for the app.  I rebooted.  After reboot, the phone seemed returned to normal. 

     

    The phone is not a lemon,  It is a free replacement I got from Apple store of a three year old iPhone 5.  That phone got a problem.  When I press the home button it does not return to the home.  Since the phone has a wake button replacement program.  I thought it may be due to the wake button.  Why not give it a try.  I made an appointment with Apple store.  The genius took a look.  He showed me that the problem is not what I thought at all.  The screen actually bulged a little near the center.  He said this is due to the batter underneath.  He replaced it free.

    I don't know why Apple Keep giving Samsung a chance to screw up apple's.
    Seriously, if i am samsung, i would totally love to see how apple get into troubles for selling the new iPhones .
    If i am samsung, I would announce this to the press: "YES, it's true, apple buy cheap chips from us, because they wanted to make more money". "We leave the best for the S7.babba"

    Don't buy a thing from your most against enemy, unless you are dumb.
    Cheaper is not always better.
