USB3 / USB 4 was enabled with an external chip in select iPads. This has a power, space, and material cost. It may not even fit in the phone space or power budget at all.
For the A17, they added USB3 to the SoC. I bet the iPhone 16 non pro will have USB3, when it gets the a17 chip.
It also could be heat related in the iPad Air, it has a thinner and lighter chassis with less metal. Thunderbolt uses a fair bit of power at 40Gb/s! Let alone say, providing 15w of power to whatever device like an external SSD.

Scroll to the "chip" section, and straight from the horse's mouth they both use a 4+4 / 8 M1, I rather doubt Apple has a variant of that chip which removes ip blocks (AFAIK the only variant is the 4+4 / 7 chip still available on the super low end MBA).

That... does not in any way affect the point?

Okay…you’re right, the only reason I don’t have a 138 core epyc cpu in my iPad is market segmentation! Darn markets.
Yes. Per Apple:
> More Innovative Technologies Packed into M1
> An Apple-designed Thunderbolt controller with support for USB 4, transfer speeds up to 40Gbps, and compatibility with more peripherals than ever.
> you’d need a teardown.
You mean like the dozens of teardowns of M1 macs when it was released, which only found retimers on the motherboard but no external controller?

I see you are wilfully obtuse and entirely unserious. I'm sorry I bothered.
Thanks for the info!
> I see you are wilfully obtuse and entirely unserious. I'm sorry I bothered.
No, you are being an asshole and a bit of idiot. I said it might be heat related - so there is a reason beyond market segmentation that apple does not include thunderbolt in the iPad air. I don't know why I am bothering either, but here we are.
Will the non-Pro version also be 3nm? Will it support USB3?
Edit to add. Their Mac didn’t have usb-c ports and that’s the only charger I had with me and no adapter. They were an Android user.
Is it though? Really? 480 Mb/s is quite fast for most applications, especially those involving a smartphone.
Any user with files large enough that this transfer is ostensibly slow is a videographer of some sort and has likely bought the pro model or at least planned for this event.
What sort of file is a "random 1-off thing" that a casual user might need to transfer, unexpectedly, over the wire, which is so large that a speed of 0.48 gigabits/sec is extremely slow?
The non-pro model can transfer a 5GB file over the wire in around a minute. Again, what is the real-world use case or scenario where a non-pro, casual user would find some random 1-off file, that is so large that the 0.48 Gbps speed is lacking?
Personally I am very excited for this transfer to happen over USB3 in the future.
Out of curiosity, what client app do you use to actually view the snapshot on the iPhone?
The latest full snapshot (including low res images) is here and clocks in around 102gb: https://dumps.wikimedia.org/kiwix/zim/wikipedia/wikipedia_en...
I live on an RV and end up working off of solar power far from cell service, so when I run out of power for Starlink there's no internet and Kiwix is super handy for relevant reading material.
In my single anecdata case, out of 15ish years of owning phones, it was a 4kx60fps video of a recital and about 30gb if I recall correctly.
Also, you are doing a classic mix-up of mega-bits vs. mega-bytes. A 30 gb file transferring at 480 megabits per second takes around 5 minutes with no protocol overhead (about 20% speed reduction) and assuming the flash on the phone can keep up and isn't doing anything else on the wire (probably another 20-40% reduction in transfer speed).
How did I mix up megabits and megabytes? I mentioned a 5 gb file transferring at the same speeds takes a minute or so. That tracks with your 30 gb:5 minute calculation.
It would have been different if I wrote MB/s (all caps)
MB/s = megabytes per second
Mb/s = Mbps = megabits per second.

> Megabits per second (Mbps) are units of measurement for network bandwidth and throughput. They are used to show how fast a network or internet connection is. Each Mbps represents the capacity to transfer 1 million bits each second, or roughly one small photo per second. It may also be expressed as Mbit/s or Mb/s.
I pay the Apple tax now, and curse Apple each time they tell me my iCloud storage is almost full. I have TERABYTES of available local storage but Apple keeps my photos hostage in their shitty iCloud world.
I would gleefully go back to managing my own photos if Apple wasn't actively trying to prevent it. /rant
Next iPhone should have no port!
I do feel that the differences and selling points of these devices vs the previous devices have gotten so trivial though.
USB C is nice, but the suggestion in their presentation that I carry around a usb charger for my Apple Watch and would charge my Apple Watch from their device “directly” or that a millimeter this way or that way in width or thickness matters at all. These things are just the most trivial differences. I can’t believe I spent over an hour watching their stupid presentation.
75MB per picture in pro raw 48MP mode. 6GB per minute with ProRes 4k video. 5 minutes of video and my data plan caps if uploaded to iCloud.
One nice addition is they allow hard drive data offloading for ProRes video and can record at 4k60.
I don't think it's that costly to continue to use the same SoC they just used in the outgoing models.
I care. I have a legitimate use for USB 3 on my phone.
My home ISP is unreliable. It doesn't care if I'm in a time sensitive meeting. When it does go away, I need to quickly get back into my meeting.
Sometimes it goes away for hours. It has also gone away for days sometimes. I need an alternate internet connection, and preferably one that doesn't require my neighbourhood to have electricity, because that also is unreliable where I live.
So I use my phone. For short durations of use, I use the Wi-Fi Hotspot feature, but for longer durations I switch to USB Tethering.
At USB 2 speeds, I'd guess, the Ethernet connection can only negotiate a 100 Mbps link speed. That is much slower than my home ISP.
The phone I use currently has USB 3 and cost me half the price of an iPhone 15.
USB-C is a major selling point for me, primarily for data transfer speeds.
The few random people who do are probably videographers looking to transfer their large video files and buying the pro models anyways.
Even android users probably aren't paying attention to what speed their USB was.
I'm shocked that is even a selling point. I've been using an iPhone and iPad for about 8 years and never transferred data this way. I've only used usb for midi or keyboard inputs where data speed was not a factor.
