    While iFixit was busy tearing down the iPhone 7 Plus, the experts at Chipworks opened up an iPhone 7 to take a close look at the chips included on the device's logic board.

    The new A10 Fusion chip at the heart of the iPhone 7 is the most significant feature to be examined, with Chipworks noting the chip is indeed manufactured by TSMC with a die size of roughly 125 square millimeters. The iPhone 7 is also confirmed to include 2 GB of memory, compared to the 3 GB found on the iPhone 7 Plus.


    The A10 is also extremely thin, due in large part to the InFO packaging technique used by TSMC which was seen as a major factor in TSMC winning exclusivity for A10 production.
    On the cellular modem side, Chipworks found an Intel part that is likely the XMM7360, paired with two SMARTi 5 RF transceiver chips and a power management chip also from Intel.

    As we previously noted, Apple is producing two different models of both the iPhone 7 and 7 Plus, with models for AT&T and T-Mobile users not including support for CDMA networks. This is apparently a result of a modem supplier split between Intel and Qualcomm, with Intel's current chips unable to support CDMA networks due to licensing issues. iPhone 7 and 7 Plus models with Qualcomm modems can support both GSM and CDMA networks.

    Finally, Chipworks notes that flash storage for the iPhone 7 is also being at least dual-sourced, with Hynix and Toshiba chips being found in its two teardown phones.

    For the rest of the details on the chips found in the iPhone 7, check out Chipworks' full rundown.

    Update: Chipworks has confirmed the A10 Fusion chip is still made on TSMC's 16 nm FinFET+ process and has shared an annotated die shot of the chip.

    2 gb.. Looks like the iPhone 7 Plus is the way to go if you'd ever plan to get one...

    Amazing how far and ahead Apple is in the chip architecture in the mobile world and yet all you have is people complaining about the headphone jack...

    Not everyone wants a 5.5 iPhone just because it has 3 GB of Ram. 2GB is still adequate for some iPhone users.

    2GB of ram? Blah. That's nothing. My Android has 6GB of ram. That automatically means its better! /s

    Main reason I'm getting one. I was originally going to pre order the 7 as I much prefer the size, but saw an article the day before saying the Plus has 3GB so quickly changed my mind. The double camera is just an added bonus to me.

    The A10 is an absolutely fantastic SoC. But we're starting to hit the law of dminishing returns for mobile phone CPU performance. An A9 to A10 is not likely going to yield significantly large performance gains in everyday life because the A9 itself was already blazingly fast. when your App load times for most normal apps is in the miliseconds, a 10% increase isn't going to be really noticed.

    Take away the most commonly used port in the world for audio, and people are going to notice.

    So no, it's not amazing that the focus is on a functionality removal, and not an incremental update thats not going to be noticed by most.

    I'd say 'most' users. I have a 6s+ and RAM has never been an issue.

    iPhone 7. The only thing that's thin... is everything.

    How so? For the typical user, would that extra 1GB make a significant difference to them?

    Now for the test of which modem is more energy efficient...intel or qualcomm....if that's even possible.

    What does all the performance and finesse matter when the phone introduces burdens and extra costs to real-life everyday scenarios?

    ...a faster processor is for more than just app load times.

    I'm well aware what a faster processor is used for. And I'm willing to bet, outside of our MR circle of geeks, and maybe a few other geek spots aroudn the web, most users are not going to notice a significant difference in most of their everyday usage.

    maybe if you keep it a long time and want to futureproof.
    at the moment: i doubt any one will notice a difference.

    Probably won't make much of a difference today, but 3GB is a decent bit of future-proofing.
    Speaking of future, October 5th can get here ANY day now. I wants my shiny.

    Too big for one handed use. Like holding a coffee while checking e-mail and texting while walking

    I'm not sure why people are so worry about RAM on iOS. 1GB on the 6 was definitely too little, but 2GB is more than enough on my 6S Plus.

    What are people doing on iOS with 4.7" screen that requires 3GB of RAM?

    2GB or ram vs 3GB
    Single vs dual camera
    1334x750 vs 1920x1080
    1960mAh battery vs 2900mAH

    If the regular sized iPhone had the spec's of the larger model it would have been my dream phone. As it stands no way I'm buying the small model, again.

    It's also a very relative thing based on what you're used to. I've had my 6 since its launch...so I'm still in the 1GB Memory section of Apple world. I have no desire to carry around a 5.5" screen anyway, so that rules me out...but I'm sure that 2gb when I get my 7 will keep me happy for the next year if not 2 years. It will be amazing to me, but maybe not to those who are used to 2gb in their phone.
