Whilst the cost to apple of the parts may be less than the cost of the phone, and it is, otherwise they wouldn't make profit, now, would they(?), the cost of all the parts individually of a device will always cost more than the completed device. This is how the entire repair industry works, from phones to dishwashers to cars. If you want ALL the parts of a device, the cheapest way of getting them all is simply buying the device.
NFC chips tend to pop up on devices without NFC from time to time, the Droid Razr had one, I’ve seen them from time to time on other phones, and now this.
I’m half guessing they’re added on in production, and nearing the end NFC gets cut from the hardware for whatever reason and it gets left there.
I’m sure some schematics, or in time, Louis rossmann will work it out (when it dying ends up killing boards)
I’d say secure enclave, but that’s the T2’s job. Maybe the T2 (coughA10cough) depended on the NFC chip it expected on iPhones, so they through it on just to keep the thing happy? I wonder if the iMac Pro has one…
Still, I’d expect NFC to be a more Macbook thing, maybe a reader under the trackpad for pairing that got scrapped?
You’ll notice that they’ve sealed the mid-area under the display bezel, with only an opening on the side furthest from the fan, nothing above the CPU, and an outlet the fan blows air out of.
I’m guessing they did this to cool both the low power, yet still warm T2, as well as draw air over the CPU.
It’s not blowing directly on a heatsink connected via heatpipe to the CPU, no, but I’m guessing they weighed up the pro’s and con’s of heatpipes, and decided that sucking air through a tightly controlled path is preferable to the bulk added by heatpipes.
It’s no different than the trashcan mac pro, is it? That just sucks air up over the heatsinks if I remember correctly.
What matters is that airflow is limited to a strict path, that’s in the left side of the laptop, over the T2 and SSD’s heatspreader, over the CPU’s radiator, through the fan, and out the right side.
