The MacBook Airs use a “computer on stick” logic board (similar but not identical to the approach used in the current iMac). Is that the board approach used in the M4 iPad Pro?
Well, now that you mention it, the logic board on the iPad Pro is also a narrow rectangle. But I really doubt they use the exact same logic board design for both devices…

The moment to up the RAM was with the new M4 iPad Pro. I wonder if they will unlock the remaining 4GB in the future, via software update.

I suspect he's talking about performance once all the AI toys are up and running, rather than now.
I’m sure they will run perfect fine on all of the Macs they support, as Apple usually ensures, and the Mac won’t be “barely performing”. We have no reason to believe it won’t run well. We just have clickbait videos trying to sell such claims with no evidence…

As to these “M4 has 12GB RAM” claims, they’re entirely assuming. There’s no reason to assume the M4 has more RAM than Apple says the configuration is. People are assuming that the model numbers or whatever are correct, and that they’re a certain chip from Micron. But that’s not necessarily true. For all we know, they could be custom ordered, they could be from another source, the numbers may have been misread. There’s lots of more reasonable explanations than jumping to assuming that Apple added more RAM in the base M4, but didn’t take the opportunity to market it, and are somehow hiding it…
 
How did this rumour about the M4 chip possibly coming with 12gb of ram come about?
In a teardown video, some people thought the number on a RAM chip means it’s a certain Micron chip that has 6GB x2 would be 12GB. But there are a bunch of assumptions involved, such as assuming they didn’t mistake the number, they’re assuming it’s that particular chip from Micron and not from another supplier possibly, or a custom chip from Micron. Again, lots of assumptions at work, and no evidence that actually definitively proves the 12GB claims.

I wonder, is it possible that the iPad 12 GB RAM chips have defective regions, and 1/3 of the chips are simply deactivated and used at 8GB, instead of being discarded? In the same way that better processors are binned and those that fail the process go into lower end devices with fewer cores activated?

How do you get 8gb out of two 6gb modules. That's a weird one
The problem is these people are assuming their 6GB modules. There’s no hard evidence for this, just some people’s interpretation of a number that could or could not have anything to do with ordinary Micron RAM chips. We don’t have any reason to assume that Apple used 12GB of RAM, but then, for whatever reason, didn’t decide to shout it from the rooftops to shut up the base spec hater crowd. This conspiracy theory breaks all believability. Far more likely that these chips are 4GB chips, and there’s no secret cabal going on.

An interesting sort of relevant observation:


Maybe they fixed a few leaks. :)

If the M4 Air comes with a cellular option (that seems like a very big if), then maybe. Another thing iPad logic boards have that Mac logic boards do not is NFC.

Apple could take the M4 iPad Pro logic board, leave out the cellular and NFC chips, and put that in the M4 Air, but I suspect they won't do that until cellular Macs become a thing.

Because some iPads shipped with 2x6. It's a bit unclear why; perhaps some kind of parts shortage.
